What is a High Temperature Non Asbestos Gasket Sheet?

A High Temperature Non Asbestos Gasket Sheet is a compressed fiber material designed to withstand extreme heat while maintaining a strong seal. Unlike asbestos gaskets, which pose health risks, these sheets are made from synthetic fibers (such as aramid, glass fiber, or mineral blends) and elastomeric binders, making them safer for workers and compliant with modern regulations.

Key Benefits of Non Asbestos High-Temp Gasket Sheets

Heat Resistance
Can withstand temperatures up to 1000°F (538°C), depending on the material composition.
Asbestos-free alternatives perform comparably to traditional asbestos gaskets in high-heat applications.

Chemical and Oil Resistance
Resists degradation from oils, fuels, and many industrial chemicals.
Ideal for use in petrochemical plants, refineries, and automotive engines.

Compression and Recovery
Maintains a tight seal under high pressure, reducing the risk of leaks.
Better recovery properties than some rubber-based gaskets.

Safety and Compliance
Asbestos-free, eliminating health risks like lung disease.
Meets international standards such as ISO 9001, ASTM F104, and DIN 3535.

Comparison: Non Asbestos vs. Asbestos Gasket Sheets

Property Non Asbestos Gasket Sheet Traditional Asbestos Gasket
Max Temperature Up to 1000°F (538°C) Up to 1200°F (650°C)
Chemical Resistance Excellent Good
Health Risks None Hazardous (carcinogenic)
Compression Strength High Moderate
Compliance Meets modern regulations Banned in many countries

While asbestos gaskets may have slightly higher heat resistance, non asbestos sheets are safer, more durable, and legally compliant, making them the preferred choice for most industries.

Common Applications

Automotive: Exhaust systems, engine gaskets.
Oil & Gas: Flange seals in pipelines and refineries.
Power Plants: High-pressure steam systems.
Manufacturing: Boilers, compressors, and heat exchangers.

Choosing the Right Non Asbestos Gasket Sheet

When selecting a high-temperature gasket sheet, consider:
Temperature range (check manufacturer specifications).
Chemical exposure (ensure compatibility with fluids in your system).
Thickness and density (affects sealing performance).
