Use:
Asbestos-free compression gasket 7900 is a general purpose economical compression gasket material plate for use in weak corrosion conditions of pipelines, equipment and licensed equipment where the medium is steam, hydrocarbons and refrigerants.
Advantages:
1. Good sealing performance greatly reduces the user's production cost
2. Multifunctional gasket properties are better than traditional economy film
3. Anti-viscosity reduces the cleaning time of sealing surface
4. Good compressibility and resilience to ensure its good sealing.
Ingredients:
Asbestos-free compression gasket 7900 contains high strength aramid fibre and its adhesive is high quality nitrile butadiene rubber (NBR)
Viscosity resistance:
All compression gasket materials have done a lot of work in developing adhesive interpreters with superior anti-viscosity properties. All compression gasket materials successfully passed the MIL-G-24696B300℉/48hrs naval facility adhesion test.
Note:
ASTM standard performance is measured on 1/16 inch thickness, but ASTM F38 is measured on 1/32 inch thickness. These properties are for general reference only and cannot be used as a basis for acceptance or rejection. The data listed in this table are within the normal range of product performance and should not be used to prepare technical specifications or solely as a basis for design.
• When the public heat pressure is above Class300, please consult the representative office.
