Non-asbestos Compressed Gaskets for High-pressure Pipe Seals with Non-asbestos Flanges

General Characteristics of Non - asbestos Jointing Gasket Sheets

Product Details

1. Composition: The gaskets are crafted from a combination of aramid fiber, non - asbestos mineral fiber, synthetic fiber, and synthetic oil - resistant rubber. They are manufactured through a process of hot - roller compression and vulcanization.
2. Product Types: Based on different temperature tolerances (the numbers indicate the peak temperature), there are the following types available:
   • CSNXB150
   • CSNXB250
   • CSNXB350
3. Product Features:
   • Excellent Adaptability and Durability: These gaskets offer good adaptability to different working conditions and have high durability. They provide reliable sealing performance, do not delaminate easily, and have a high yield rate.
   • Economical Solution: They serve as an economical choice for sealing gaskets and exhaust, as well as manifold gasket materials.
   • Certified and Asbestos - Free: They are certified by ISO9001 UKAS, ensuring that they are 100% asbestos - free.
   • Outstanding Oil Resistance: They exhibit excellent resistance to oil, which is crucial for many applications.
4. Product Applications:
   • Engines
   • Air compressors
   • Gearboxes
   • Pipeline and flange sealing
5. Product Sizes:
   • The thickness of the gaskets can range from 0.5 mm to 5.0 mm.
   • Standard sizes include 15001500 mm, 15002000 mm, 15004500 mm, 12701270 mm, and 1270*3810 mm.
   • Additionally, we can customize the size according to the clients' specific requirements.
