Taiwan imported food grade O-rings, imported food grade O-rings, high temperature silicone seals Taiwan Taiwan Wall -OTP top professional production of imported food grade O-rings, imports of high temperature O-rings, imported low temperature O-ring, imports of corrosion-resistant O-ring, O-ring imported oil, imported wear resistant O-ring. Imported food grade O-ring material can be divided into: silicone rubber, nitrile rubber, Viton. If the requirements are not very strict and not direct food contact, then the choice of NBR, fluorine rubber material on it. If direct contact with the people's diet, sure to use silicone rubber material, while silicone rubber material in all material temperature is the highest performance and most stable, silicone rubber is resistant to high temperature up to 250 degrees. Wal-top food grade seals, high temperature O-ring is imported products in the most cost effective seal. Our seal species: O-ring, star-ring, ED seals, rubber balls, seals, washers, rubber flat washer, USH seals, shaft seals, seal holes, Y type Wal-top seal ring ...... advantages of the product: 1) performance, long life, work life dynamic pressure seal 5-10 times higher than conventional rubber seal products, up to a few times, in some can seal matrix with life under the conditions. 2) friction is small, dynamic and static friction equal to "0" shaped rubber ring. 3) strong wear resistance, sealing surface wear and tear with automatic elastic compensation. 4) rubber has good self-lubricating properties. Can be used for oil-free seal.
