INBOND CORK GASKET SHEET
Inbond Cork Sheet
Type 800
Description:
TYPE 800 is produced from superior quality cork granules bonded with synthetic rubber (natural/nitrile/neoprene). Cork materials have exceptional compressibility and resilience. They also offer a high mechanical strength. Cork has wide applications in automotive/industrial/electrical (transformers), petrochemical, oil & gas, etc. and also confirmed many general sealing applications.
