1. Rubber O-ring Introduction
It is rubber ring with O-shaped cross section, it has high elasticity, insulation and long service life.
It is easy to manufacture, inexpensive and reliable, so it is commonly used in machinery manufacturing,
automotive,electrical, medical and other industries,and plays the role of sealing, insulation, cushioning,
fixing, etc. Therefore, rubber O-ring is one of the most commonly used seals in global machinery.
2. Raw Material Selection
Rubber O-ring has a variety of raw materials. Different materials have different properties and prices.
The order of material prices is: NBR<SIL<EPDM<CR<ACM<FKM<HNBR<FVMQ
We should choose the appropriate material according to its use environment.
The following table is the main characteristics of the material. If you want to know more about a
