C-8200 — Chemical-resistant glass-fiber gasket material
C-8200 is a glass-fiber reinforced gasket sheet with an acid-resistant binder, designed for long-term sealing in aggressive chemical services. Excellent resistance to strong acids/alkalis, low creep and robust mechanical performance — datasheet available on request.
Description
C-8200 is a premium gasket material engineered for aggressive chemical environments. Manufactured from glass fibers consolidated with a specially formulated acid-resistant binder, C-8200 combines excellent chemical compatibility (notably with mineral acids and alkalis) with mechanical robustness and dependable sealing behavior under flange load. It is well suited where both chemical resistance and dimensional stability are required.
Key benefits
- High chemical resistance — effective against most mineral acids, alkalis, ketones and aldehydes.
- Low creep / good relaxation performance — designed to retain gasket stress under load.
- Strong mechanical properties and good sealability for demanding flange connections.
- Off-white appearance and standardized manufacturing for consistent performance and traceability.
Typical applications
-
Chemical process plants handling alkaline media (pH-high environments).
-
Glass-lined reactors, plastic/FRP flanges and other delicate flange faces where low-stress sealing is required.
-
Heat exchangers, pumps and valves in corrosive environments
-
Petrochemical and specialty chemical installations
Why choose C-8200?
Choose C-8200 when your process demands superior chemical resistance combined with stable, dependable sealing performance. Its glass-fiber reinforced construction with an acid-resistant binder provides durable resistance to mineral acids, alkalis and aggressive organic solvents while delivering low creep and good sealability under sustained flange stress. For applications such as glass-lined reactors, corrosive piping and high-maintenance environments, C-8200 helps reduce retightening frequency and maintenance downtime — making it a reliable choice for long-term, aggressive chemical service.
