Low Chloride A1 Non-Combustible Elastomeric Insulation Board for Stainless Steel Anti-Corrosion Systems

In modern industrial environments such as automotive manufacturing, semiconductor factories, pharmaceutical plants, and clean HVAC systems, insulation materials must ensure not only thermal efficiency, but also corrosion protection and fire safety compliance.

The Low Chloride A1 Non-Combustible Faced Elastomeric Insulation Board is developed to solve these critical engineering challenges in stainless steel piping and equipment systems.

Proven Project Applications

This product has been successfully applied in major industrial facilities, including:

• Volkswagen Group automotive manufacturing plant (Hefei, China)
• Lexus production and HVAC systems

Project Highlights:

✔ Stainless steel piping corrosion protection
✔ A1 fire-rated insulation for high-risk industrial zones
✔ Improved installation efficiency in large-scale factory HVAC systems
✔ Long-term stable performance in continuous production environments

These projects demonstrate the material’s reliability in real industrial operating conditions, not just laboratory testing.

1. Anti-Corrosion Protection for Stainless Steel Systems

Stainless steel is widely used in industrial piping due to its corrosion resistance. However, chloride ions in conventional insulation materials can cause stress corrosion cracking (SCC) in humid environments.

To prevent this issue, our insulation board controls:

• Total chloride content ≤ 900 ppm
• Compliant with GB/T 17393-2008 stainless steel insulation standard

Key Benefit:

✔ Prevents SCC corrosion
✔ Protects long-term integrity of stainless steel pipelines
✔ Reduces maintenance and replacement costs

2. A1 Non-Combustible Fiber Facing for Fire Safety

The product is laminated with a grey fiber textile A1 non-combustible facing, eliminating the need for additional protective layers.

Fire Performance:

• A1 non-combustible (GB 8624 / EN 13501-1)
• No melting or dripping under fire
• No toxic smoke emission

Application Areas:

• Automotive paint shops
• Mechanical and HVAC rooms
• Industrial ceiling and pipe systems
• High fire-risk zones

3. Integrated Protection System

The fiber facing provides multiple functions in one layer:

Mechanical Protection

• Resistant to tearing and impact
• Protects insulation during installation and maintenance

Moisture & Vapor Control

• High vapor resistance
• Prevents condensation
• Maintains long-term thermal stability

Industrial Appearance

• Clean grey finish
• No aluminum foil wrapping required
• Suitable for exposed piping systems

4. Industrial Applications

This insulation system is widely used in:

• Automotive manufacturing plants
• Semiconductor cleanrooms
• Pharmaceutical facilities
• Food processing factories
• Data centers
• Industrial HVAC and piping systems

5. Key Technical Advantages

Compared with conventional elastomeric insulation materials:

✔ Ultra-low chloride formulation (≤900 ppm)
✔ A1 non-combustible fire-rated surface
✔ Integrated vapor barrier system
✔ Improved mechanical durability
✔ Faster installation and lower labor cost
✔ Long service life in harsh environments

Conclusion

The Low Chloride A1 Non-Combustible Faced Elastomeric Insulation Board is designed for modern industrial systems that require high safety, corrosion resistance, and installation efficiency.

With proven applications in Volkswagen and Lexus manufacturing facilities, it is a reliable solution for stainless steel HVAC and piping systems in demanding environments worldwide.
