Product Description

This high-performance thermal insulation material utilizes butyronitrile rubber and polyvinyl chloride (NBR/PVC) as the main raw materials. Manufactured through advanced foaming and specialized procedures, it forms a soft, closed-pore foaming heat-insulating structure. Formulated entirely without Chlorofluorocarbons (CFC) and Formaldehyde, it delivers lasting and stable thermal conductivity performance alongside superior fire protection (oxygen index ≥ 40%). Recognized for its anti-cracking properties, high elasticity, and broad temperature endurance, its outstanding corrosion resistance prevents premature aging, ensuring a simplified installation process and an extended service lifespan.

Eco-Friendly Formulation

Zero Chlorofluorocarbon (CFC) and Formaldehyde content ensures safe application and environment protection.

High Fire Resistance

High-level flame retardant capabilities featuring an oxygen index of 40% or higher.

Exceptional Durability

High elasticity combined with cracking resistance and stable thermal parameters over time.
