Nitrile Rubber Sheet
Viton Rubber Sheet is a Premium rubber elastomer resistant to chemicals and useful for sealing against acids and lyes of any concentration,
solvents, aliphatics and aromatic hydrocarbons, Freon 12, oils and fats and gasoline
It has excellent resistance to weathering and ozone. Premium Viton rubber sheet has extraordinary resistance to heat with resistance also to
low temperature and is self extinguishing, Viton rubber sheet has excellent compression set in compression at high temperatures. It's extremely
resistant to alkalis, including oxidants.
Industrial Gaskets Viton rubber sheet has been designed primarily for use as a gasket, flexible strip, pad or lining and is mainly used for Sealing,
Insulation, Isolating and protecting steel or other surfaces of equipment
It is mainly used for corrosion and high temperature applications such as chemical storage transfer and processing, but it can be used for a wide
range of applications including Flange Gaskets on pipes and tanks, Lining of pipes and tanks and variety of sealing applications
Advantages
