Rubber seal ring is formed by one or several parts of the cover, fixed in a ring or a washer bearing and another ring or gasket contact or the formation of the labyrinth of narrow gap, to prevent leakage of lubricating oil and foreign matter.

The rubber sealing ring is used to install on all kinds of mechanical equipment, in the specified temperature and pressure, as well as different liquid and gas, in a static or moving state seal.

Material analysis of rubber sealing ring:

1, fluorine rubber: high temperature resistance, can be used in the -+250 C -30 C environment, the strong oxidizing agent, oil, acid and alkali resistance. Usually used for high temperature, high vacuum and high pressure environment, suitable for oil environment. Because of its excellent properties, it is widely used in petroleum, chemical, aviation, aerospace and other departments.

2, silicone rubber has outstanding resistance to high temperature performance, keep good elasticity in the temperature range of -70 DEG -+260 DEG within, and have the advantages of ozone resistance, weather resistant, suitable for the thermal mechanical seal gasket. Because there is no toxicity to make insulation, insulation products and medical rubber products.

3, nitrile rubber has excellent oil resistance and aromatic solvent properties, but not resistant to ketones, esters and chloride by medium, so the oil resistant sealing products with nitrile rubber.

4, chloride butyl rubber: with good oil resistance, solvent resistance, chemical medium and other properties, but not resistant to aromatic oil, which is characterized by good weather and aging and ozone aging properties. Production of commonly used in the production of rubber and the diaphragm and the diaphragm and the general vacuum sealing products;

Three, 5 yuan per day: with good temperature resistance, weather resistance, aging and ozone aging performance, usually doors and windows sealing strip, the most widely used in the automotive industry.

6, PTFE gasket is PTFE and high quality rubber material, the special production process of new sealing material compound and into, it has good comprehensive characteristics of PTFE and rubber, the products possess excellent corrosion resistance, and high temperature resistant, non-toxic, anti adhesive, and has good elasticity and sealing.
