Wholesale High Tensile Strength Black NBR Rubber Round Hole Flat
Gasket
Product Description
Rubber products are made of rubber raw materials for the mixing
machine after the mixing of rubber as raw materials, according to
the characteristics of rubber products required in the mixing of
the design formula, and set the required product hardness. The
product is molded by rubber plate vulcanizing machine. After the
product molding, the final edge treatment, the product surface
treatment is smooth without burr.

NBR is mainly used to manufacture oil resistant rubber products.
Acrylonitrile content in nitrile butadiene rubber (%) has 42 ~ 46,
36 ~ 41, 31 ~ 35, 25 ~ 30, 18 ~ 24 and other five kinds. The more
acrylonitrile content, the better oil resistance, but cold
resistance is decreased. It can be used in 120℃ air or 150℃ oil for
a long time. In addition, it also has good water resistance, air
tightness and excellent bonding properties. It is widely used to
produce all kinds of oil-resistant rubber products, a variety of
oil-resistant gaskets, gaskets, bushing, flexible packaging,
flexible hose, printing and dyeing roller, cable adhesive
materials, etc. It has become an indispensable elastic material in
automobile, aviation, petroleum, photocopying and other industries.
