Use:
Asbestos-free compression gasket 4000 with a maximum temperature of 500° F(260 ° C) for short term use and 350° F(175 ° C) for long term use, and a working pressure of 1000psi(68 bar). Applicable working medium for steam, oil, water, weak base, weak acid, hydrocarbon inflammation and solvent. Advantages:
1. Economic gasket greatly reduces the production cost of users
2. Point resistance reduces the cleaning time of the seal
3. Good compressibility and resilience ensure good sealing. Ingredients:
Asbestos-free compression gasket 4000 contains high strength mineral fibers and is glued with nitrile synthetic rubber (NBR). Its positive and negative sides have film release agent, so it has good anti - viscosity. Note:
ASTM the experimental results of performance except F38 are based on 1/32 (0.8mm) plate thickness materials. This is general guidance and should not be the only way to select or exclude such materials.
