About rubber and plastic products
There are many kinds of rubber and plastic products, which can be divided into static sealing products and dynamic sealing products according to the working state. O-rings are widely used to seal static and reciprocating parts. Oil seals are widely used to seal rotating shafts. O-rings and oil seals account for more than half of the total number of sealing products. The work of the rubber seal is realized by the contact between the rubber and the sealed part. For example, the oil seal is in contact with the rotating shaft surface with a small area of its lip under a certain pressure and is not leaked under the action of fluid lubrication. The O-ring is The rubber ring is given a section compressive force to achieve sealing, etc., so the rubber material is required to have high elasticity, good oil resistance and aging resistance.
