Why Is Lightweight Thermal Insulation Becoming More Important?

Industrial equipment operating at elevated temperatures commonly faces several challenges:

• Continuous heat loss
• High enclosure surface temperatures
• Increased heater energy consumption
• Thermal exposure of nearby electronic components
• 設置スペースが限られている
• 装置重量
• Difficult installation in complex geometries

Traditional industrial insulation materials include:

• ガラス繊維
• ロックウール
• セラミックファイバー
• 微多孔断熱材
• Aerogel materials
• Rigid insulation boards

Each material has its own suitable temperature range and application environment.

However, modern industrial equipment is increasingly moving toward:

lower weight, smaller footprints, higher automation and better energy efficiency.

This creates demand for insulation materials that are:

lightweight, easy to process, adaptable to complex structures and capable of providing multiple functions.

メラミンフォーム is one material worth evaluating within this category.

1. Industrial Equipment Has Less Available Space

Modern automated equipment, battery production lines and precision manufacturing systems often contain:

• モーター
• センサー
• パイピング
• 電気部品
• 発熱体
• アセンブリの移動

If the insulation layer becomes too thick, it can directly affect:

• 機器の寸法
• パイプルーティング
• 電気配線図
• メンテナンスアクセス
• エンクロージャーの設計

For this reason, industrial insulation increasingly focuses on:

how to achieve sufficient thermal resistance within limited installation space.

2. Equipment Lightweighting Is Becoming More Important

In large enclosures, tanks and machine housings, insulation may cover a significant surface area.

Reducing insulation density can help lower:

• 構造荷重
• Support-frame weight
• Moving-module weight
• Overall equipment weight

This can be particularly valuable in:

• 自動化機械
• 自動車製造装置
• 電池製造装置
• Rail equipment
• 空調システム
• Mobile industrial systems

3. Complex Equipment Requires Easy-to-Process Materials

Industrial equipment rarely consists only of flat surfaces.

Typical geometries may include:

• 円筒形タンク
• 湾曲したハウジング
• パイピング
• 狭い空洞
• Irregular spaces

メラミンフォームは以下の方法で加工できます。

• 切断
• ダイカット
• 溝入れ
• 穿孔
• 整形
• ラミネート加工
• 接着剤バッキング
• アルミ箔ラミネート加工

This allows the material to adapt more easily to complex industrial structures.

For equipment manufacturers, this can translate into:

faster assembly, less on-site processing and greater design flexibility.

Hot Melt Adhesive Equipment: A Strong Application Direction

Hot melt adhesive systems represent one of the most relevant application areas for lightweight high-temperature insulation.

代表的な装備は次のとおりです:

• Hot melt adhesive tanks
• Adhesive melting units
• Glue reservoirs
• Hot melt transfer systems
• ディスペンシング装置
• Hot melt hose systems
• Adhesive modules in packaging machinery

These systems must continuously maintain the adhesive at a controlled working temperature.

If insulation is insufficient, the equipment may experience:

• Continuous heat loss from the tank
• More frequent heater cycling
• より高いエネルギー消費
• Higher enclosure temperatures
• Additional thermal stress on nearby electronic components
• Reduced temperature stability

The insulation layer therefore functions as an important part of the overall thermal management system.

A Typical Operating Condition: Approximately 177–204°C

In a recent industrial hot melt adhesive equipment evaluation, the typical operating condition was approximately:

177°C during normal operation

with a maximum continuous condition of approximately:

204°C

The insulation material was positioned between:

an aluminum hot melt adhesive tank and the external equipment enclosure.

A simplified structure can be represented as:

ホットメルト接着剤
↓
アルミタンク
↓
断熱層
↓
機器筐体

The key engineering question was not simply:

“Can the material withstand 204°C?”

More relevant questions included:

• Does the material become brittle after long-term heat exposure?
• Does it retain sufficient structural integrity?
• Is the material flexible enough during initial assembly?
• What insulation thickness is required?
• Would an air gap improve performance?
• Should an aluminum foil reflective layer be added?
• What final enclosure temperature can be achieved?
• Can nearby electronic components be better protected from heat?

これは重要な原則を示している。

Industrial insulation should be evaluated as a complete heat-transfer structure, not only by the maximum temperature rating of one material.

Why Consider Melamine Foam for Lightweight Industrial Insulation?

メラミンフォーム is a low-density, open-cell thermoset foam material.

Several characteristics make it worth evaluating for industrial thermal management.

低密度

One of the most important properties of melamine foam is its low weight.

For large equipment surfaces and tank insulation, low-density materials can help reduce:

• Insulation layer weight
• 構造荷重
• サポート要件
• Overall equipment mass

This makes melamine foam particularly relevant for:

lightweight industrial equipment insulation.

Easy Cutting and Shaping

メラミンフォームは以下のように加工できます。

• シート
• ダイカットパーツ
• カスタムシェイプ
• Grooved components
• 穴あき部品
• 積層構造
• Adhesive-backed parts
• Foil-laminated components

これにより、次の場合に適しています。

• 戦車
• 機器ハウジング
• Piping areas
• 曲面
• 狭いスペース
• Irregular cavities

For equipment manufacturers, this can reduce complicated field fabrication.

Thermal Insulation and Sound Absorption Can Be Combined

Industrial equipment often has both thermal and acoustic challenges.

一般的な騒音源には以下のようなものがあります。

• 扇
• コンプレッサー
• モーター
• エアフロー
• Enclosure reflections

Because melamine foam has an open-cell structure, it can also provide sound absorption.

This means that in selected equipment, it may support:

thermal insulation + sound absorption

within the same material layer.

潜在的な用途には次のようなものがあります。

• HVAC機器
• ヒートポンプ
• コンプレッサー
• ファンハウジング
• Automated equipment enclosures
• Industrial acoustic enclosures

For space-constrained equipment, combining functions can help reduce the number of separate material layers.

Why Aluminum Foil Composite Structures Matter

Heat transfer in industrial equipment typically involves:

• 伝導
• 対流
• 放射線指数

For high-surface-temperature tanks or heating equipment, simply increasing foam thickness is not always the most efficient design approach.

A composite structure may be considered:

熱源
↓
Metal wall
↓
エアギャップ
↓
Aluminum reflective layer
↓
メラミンフォーム
↓
機器筐体

この構造では：

the aluminum foil primarily helps reduce radiative heat transfer

while melamine foam can provide:

• 熱抵抗
• 軽量化
• Space filling
• 吸音

For equipment with limited installation space, this type of multilayer design can be worth evaluating through actual thermal testing.

Where Can High-Temperature Melamine Foam Be Used?

1. Hot Melt Adhesive and Glue Equipment

Potential equipment includes:

• Hot melt tanks
• Adhesive melting units

This is one of the most relevant industrial application areas for further development.

2. Industrial Heating and Drying Equipment

潜在的な用途には次のようなものがあります。

• 工業用オーブン
• 加熱室
• 乾燥装置
• 熱処理装置
• 工業用ヒーター
• Temperature-control modules

メラミンフォーム is especially worth evaluating for:

internal enclosure insulation and complex-space filling.

For very high-temperature furnaces or direct high-heat-flux environments, other high-temperature materials may remain more appropriate.

3. Battery Manufacturing Equipment

Battery production uses a wide range of thermal process equipment, including:

• Electrode drying equipment
• 加熱室
• 熱処理システム
• Battery production thermal modules
• Formation-related equipment

These systems may require attention to:

• 軽量化
• 限られたスペース
• エネルギー効率
• 火災の挙動
• クリーンな生産環境
• Automated installation

Additional validation may also be required for:

• 粒子放出
• VOC
• 長期熱安定性
• ファイアーパフォーマンス
• Compatibility with equipment design

For this reason, final material selection should be based on actual equipment requirements.

4. Automotive Manufacturing Equipment

Modern automotive manufacturing uses large quantities of:

• ホットメルト接着剤
• 構造用接着剤
• シーラント
• Battery bonding materials
• Heat-curing materials

これにより、以下の需要が生まれます。

• Adhesive heating equipment
• オーブン
• 熱処理装置
• Battery manufacturing systems

As electric vehicle production becomes increasingly automated, equipment manufacturers are paying greater attention to:

weight, space, energy consumption and maintenance efficiency.

Lightweight insulation materials can therefore provide an additional engineering option.

5. Precision Electronics and Semiconductor-Related Equipment

Some precision electronic systems contain localized heat sources that must be thermally isolated.

可能性のある分野は以下のとおりです。

• Local heating modules
• 精密熱処理装置
• Heated chambers
• Internal insulation structures

These applications generally require stricter evaluation of:

• 清浄表面
• 粒子生成
• VOC
• ファイアーパフォーマンス
• 長期安定性

A more appropriate positioning is therefore:

a lightweight insulation candidate for engineering validation.

6. Food and Pharmaceutical Processing Equipment

Potential equipment includes:

• 加熱タンク
• 混合容器
• Syrup tanks
• Chocolate processing equipment
• Hot liquid tanks
• Heated process equipment

典型的な目標は次のとおりです:

• Reducing heat loss
• プロセス温度の維持
• Lowering enclosure temperature
• エネルギー消費の削減

しかし、以下の点を区別することが重要です。

direct product-contact areas

(NAIST) と

non-contact equipment insulation areas.

Melamine foam should first be evaluated for:

non-direct-contact insulation locations.

7. HVAC, Heat Pump and Compressor Equipment

This is another important development area because these systems often experience both:

thermal challenges and noise challenges.

代表的な装備は次のとおりです:

• ヒートポンプ
• HVAC ユニット
• Industrial heating units

8. Rail and Other Lightweight Equipment

In some rail and specialized industrial equipment, material weight is itself an important design factor.

可能性のある分野は以下のとおりです。

• 装備収納部
• 熱管理モジュール
• 暖房システム
• Lightweight insulation components

These applications may also require validation of:

• ファイアーパフォーマンス
• 喫煙行動
• 毒性
• 長期熱老化
• 耐振動性

Material selection should therefore follow the applicable industry standards and project requirements.

How Does Melamine Foam Compare with Traditional Insulation Materials?

The correct selection logic is not:

“Which material is the best?”

The better engineering question is:

“Which material best matches the equipment temperature, thickness, weight and installation structure?”

Can Melamine Foam Replace Ceramic Fiber?

It should not be viewed as a direct replacement in every application.

Ceramic fiber is generally more suitable for:

• 高温
• 高い熱流束
• 炉
• Extreme high-temperature industrial systems

Melamine foam is more relevant for:

lightweight insulation in approximately 150–250°C industrial equipment environments.

The two materials solve different engineering problems.

For many medium-to-high-temperature systems, the objective is not to select the material with the highest possible temperature capability.

目標は達成することです。

sufficient thermal performance with lower weight, less thickness and easier installation.

How Should Industrial Insulation Thickness Be Determined?

It is not accurate to assume that:

200°C automatically requires 20 mm or 25 mm insulation.

Appropriate thickness depends on:

• Heat-source temperature
• 周囲温度
• 連続運転時間
• 金属壁の厚さ
• 設置可能スペース
• Maximum allowable enclosure temperature
• Air-gap thickness
• 熱放射
• 反射箔
• 強制送風

For example, with the same approximately 200°C heat source:

10 mm、20 mm、25 mm

insulation structures may produce significantly different surface temperatures.

If the design also includes:

• An air gap
• アルミ箔
• A larger enclosure spacing

the overall heat-transfer result can change further.

A more reliable development process is:

material selection → preliminary thermal assessment → sample testing → equipment validation

This combination may be suitable for the development of higher-performance thin industrial insulation components.

What Information Is Needed Before Selecting Industrial Insulation?

For an initial engineering evaluation, it is helpful to provide the following information.

温度データ

• 通常の動作温度
• 最大連続温度
• 短期ピーク気温

構造データ

• Heat-source material
• 断熱材の位置
• 設置可能スペース

This information is more useful than asking only:

“What is the maximum temperature of your foam?”

よくある質問

Can Melamine Foam Be Used Continuously Around 200°C?

Suitability for continuous use depends on the material grade, exposure duration, installation structure and long-term aging requirements.

For continuous conditions near 200°C, the following should be evaluated:

• 長期熱老化
• 寸法安定性
• もろさ
• 構造的完全性
• Actual equipment performance

Short-term temperature resistance alone should not be used to determine long-term suitability.

Is Melamine Foam Suitable for Hot Melt Adhesive Equipment?

Hot melt tanks and adhesive melting systems are among the most relevant areas for further evaluation.

Melamine foam can be especially attractive when the equipment requires:

• 軽量化
• 設置スペースが限られている
• 簡単に切れる
• 簡単な組み立て
• 熱損失の低減

Can Aluminum Foil Improve Thermal Insulation?

In equipment where thermal radiation is significant, a properly designed aluminum reflective layer can help reduce part of the radiative heat transfer.

パフォーマンスは以下に依存します:

• Foil position
• 表面の向き
• エアギャップ
• Heat-source temperature
• Overall system design

Aluminum foil should therefore be considered as part of the complete insulation structure rather than as an isolated material layer.

What Is the Difference Between Melamine Foam and Aerogel?

Melamine foam is more associated with:

• 軽量化
• 簡単な処理
• 吸音
• Structural adaptability

Aerogel materials are more associated with:

• 低い熱伝導率
• 薄い断熱材
• Higher-performance thermal control

For some high-value equipment, the two materials can also be combined.

How Do I Choose Between 10 mm, 20 mm and 25 mm Thickness?

Thickness should be determined based on:

• Heat-source temperature
• 周囲温度
• Target enclosure temperature
• エアギャップ
• 金属構造
• 動作時間
• 気流条件

The insulation thickness should not be selected only according to the material temperature rating.

What Temperature Range Is Suitable for Melamine Foam?

For industrial applications, it is more accurate to evaluate the actual service conditions rather than assigning one absolute operating-temperature limit.

適合性は以下に依存します：

• Continuous exposure time
• 熱老化
• 構造要件
• 機械的要件
• 設置場所

For equipment operating in approximately 150–250°C environments, melamine foam can be considered as a lightweight insulation candidate for engineering evaluation.

Applications approaching the upper end of this range should include more extensive long-term thermal aging and equipment-level testing.

From Material Supply to Lightweight Industrial Thermal Management

Industrial insulation selection has traditionally started with a material name:

“We need a foam.”

“We need glass fiber.”

“We need an insulation blanket.”

But modern industrial equipment design increasingly focuses on a different question:

How can heat be controlled within limited thickness, limited weight and practical installation constraints?

SINOYQX is therefore exploring integrated industrial insulation structures using:

• メラミンフォーム
• Aluminum reflective layers
• High-temperature composite materials
• エアロゲル断熱材
• Custom die-cut processing

The objective is to develop:

lightweight high-temperature insulation solutions for industrial equipment.

The focus is not only on the material itself, but on balancing:

temperature, thickness, weight, installation method and final thermal performance.

結論

High-temperature melamine foam is not intended to replace every conventional industrial insulation material.

Its strongest development direction is:

medium-to-high-temperature equipment + lightweighting + limited space + complex geometry + easy processing + combined thermal and acoustic performance.

次のようなアプリケーションの場合:

• ホットメルト接着剤装置
• 産業用暖房設備
• Industrial drying equipment
• 電池製造装置
• Automotive production equipment
• 空調システム
• ヒートポンプ

melamine foam can be evaluated as a lightweight insulation option.

SINOYQX can also explore customized structures using:

• メラミンフォーム
• アルミ箔複合材
• High-temperature adhesive-backed structures
• Aerogel composites
• Custom die-cut insulation parts

to better match the actual operating conditions of industrial equipment.
