High-Temperature Ceramic Fiber Gasket Solutions for Industrial Sealing Systems

Our premium 500℃ rated ceramic-reinforced sealing sheets offer superior performance for thermal energy applications. Available in thicknesses from 0.5mm to 5.0mm, we recommend selecting the minimal required thickness for optimal compression sealing in your specific operational conditions.

Technical Specifications:
This advanced composite material combines aramid polymer fibers with nitrile-based elastomers, engineered through thermocompression molding for exceptional durability. The formulation demonstrates excellent chemical resistance against hydrocarbons, lubricants, and aqueous solutions, maintaining integrity across multiple fluid exposure scenarios.

Performance Grades:
Three thermal classifications available (continuous operation ratings):
CSNXB150: -50℃ to +150℃ service range
CSNXB250: -40℃ to +250℃ thermal capacity
CSNXB350: -30℃ to +350℃ peak tolerance

Key Advantages:
• Certified asbestos-free composition (UKAS ISO 9001 verified)
• Multi-layer structural integrity prevents delamination
• Cost-effective production efficiency with high material yield
• Superior dimensional stability across thermal cycles
• Optimized for high-pressure flange applications

Industrial Implementations:
Ideal for sealing solutions in:

• Thermal power generation systems

• Combustion engine assemblies

• Pneumatic transmission units

• Marine propulsion infrastructure

• Petrochemical distribution networks
