Compressed Asbestos Fiber (CAF) gaskets are high-performance sealing elements made from asbestos fibers blended with rubber binders (like SBR, NBR, or Neoprene) and fillers, then compressed into sheets. They offer excellent thermal stability, high pressure resistance, and durability in harsh industrial environments, commonly sealing steam, oil, gas, and chemicals.
Key Characteristics & Features
Composition: Asbestos fiber (often chrysotile) mixed with rubber and vulcanized.
Temperature Range: Good resistance, often operating up to (in some grades).
Pressure Resistance: High, suitable for high-pressure industrial, oil, and steam pipelines.
Physical Properties: Durable, low creep characteristics, and good compressibility/recovery.
Versatility: Resistant to water, steam, gases, oils, and mild acids/alkalis.
Applications
Used extensively for pipe joints, flange connections, boiler manholes, and engine systems.
Ideal for industries involving high-temperature/high-pressure systems, such as refineries, chemical plants, and power generation.
