Non-asbestos Jointing Sheet, Compressed Non-asbestos Sheet Gasket
Description:
The products made of asbestos are rejected step-by-step when demanding more and more on the health and environment-protection. Expandable Teflon and flexible graphite are used much more widely than ever in modern industry.althrough they are gradually replace the asbestos gasket,they cann’t do it completely because they have some defect. So the non-asbestos joint sheet becomes the best replacement of asbestos planking.
Compressed non-asbestos sheet gasket is a general purpose sheet material reinforced with high-grade asbestos-free fibers and bound with heat-resistant nitrile rubber. It is a good alternative to compressed asbestos gasket and suitable for sealing off water,seawater,alkaline,hot oil organic solvent,and all applications where higher demands on temperature and pressure resistance have to be met and where non-critical gaseours and liquid media have to be sealed off.
SL-3314 This gasket has balanced material composion of high-grade aramid fibres,special fillers and NBR rubber (nitrile butadiene rubber) with A310 anti-stick coating. It demonstrates good stress relaxation,favorable cost-performance in wide range of applications such as utility or sanitary applications(gas and water supply),chemical plant,steel works,ship building,oil refinery,power plant,pipeline construction,plant and machine bulding industry.
Applications:
It has wide range of applications such as utility or sanitary applications (gas and water supply), chemical plant,steel works, ship building,oil refinery,power plant,pipeline construction,plant and machine bulding industry.
Specifications:
A premium compressed sheet gasket material comprised of an engineered blend of aramid fiber, high quality fillers and SBR binder.
