NBR Molded Rubber Parts High Temperature Resistance , Auto Rubber Parts 70


Mold rubber parts are flexible rubber seals that stretch-fit onto the shaft and rotate with the shaft against a counter face. They are specifically designed to protect the primary seal from contaminants. These seals are not designed to seal pressure differentials or to seal against fluid levels; they are primarily for contamination exclusion. The seal design utilizes centrifugal force to prevent intrusion of contaminants into the bearing chamber.


Advantage: excellent resistant to gasoline and Fat hydrocarbon oil, second only to TR, ACM and FKM, better than other general rubber. Good heat resistance, good air tightness, abrasion resistance and water resistance, strong cohesive force.
Disadvantage: poor cold resistance and ozone resistance, low strength and bad flexibility, poor acid resistance, bad electrical insulation and polar solvents resistance.
Operating Temperature: about -40°C~+100°C.
Application: mainly used in manufacturing all kinds of oil-resistant products, such as rubber hoses and seals, etc.
