4.Specifications of the gasket:
1.A good compression ratio and elasticity.
2.With plastic appropriate, after pressing can adapt to the sealing surface and sealing surface uneven fill the gap, to ensure good sealing performance with the temperature and pressure in the system of alternating case.
3.With excellent corrosion resistance, not to be damaged in some extreme medium, does not have the expansion and contraction.
4.Under the condition of high temperature softening, does not creep; under the condition of low temperature hardening, does not shrink.
5.FAQ
Ask 1: Why some supplier give me the price much cheaper than you?
Answer:1.They wanna attract your attention,while you contact with them,they would raise the price by any reason.
               2.They willn't provide the high qualities to you cause it had the cheap price.

Q:Which kind of rubber has the best wear resistance?
Three yuan ethylene propylene rubber introducedThree yuan ethylene propylene rubber is ethylene, propylene and non conjugated diene three yuan copolymer, began commercial production in 1963. The consumption of the whole world is 800 thousand tons every year. The most important feature of EPDM is its superior oxidation resistance, ozone resistance and corrosion resistance. Because three yuan ethylene propylene rubber belongs to polyolefin family, it has excellent curing property. Of all rubbers, EPDM has the lowest specific gravity. It absorbs large amounts of fillers and oils and has little effect on properties. Therefore, rubber compounds with low cost can be made.Viton (fluorocarbon rubber) is a synthetic rubber containing fluorine, fluorocarbon rubber high temperature resistance, oil resistance and various chemical erosion characteristics, is the science and technology of modern aviation, missiles, rockets, space navigation and so on the tip of indispensable material. In recent years, along with the automobile industry on the reliability and safety requirements continue to improve, the amount of fluorocarbon rubber in cars is also growing rapidly.
Q:Why do rubber products Blister?
Foaming reasons of rubber products:1 vulcanization is not sufficient, the temperature is too low or time is too short, so that the volatile compounds produced during curing have not been cleaned out;2, the vulcanizing pressure is insufficient, the detained gas and sulfur volatile matter can not be discharged in time.3, there is air or moisture in the glue;4, curing temperature is too high, the surface of the gum material premature vulcanization, hindered the rubber material in the steam, air free precipitation.
Q:What are the uses of ethylene propylene rubber?
Ethylene propylene rubber (EPR) is the most widely used automotive industry. It is mainly used in automobile seals, radiator hoses, spark plug sheaths, air conditioning hoses, rubber pads, hoses and so on. In the automotive sealing industry, mainly the use of EPDM, elastic characteristics of ozone resistance, weather resistance, EPDM rubber type ENB has become a main material of automobile rubber seal, domestic consumption has exceeded 10 thousand tons, but due to its variety, half rely on imports.
Q:How to distinguish between silicone hose and rubber tube by appearance?
Silicone hose is relatively soft, flexible, and looks better than other rubber tube gloss, color is mostly red, blue, translucent and other colors. Others, such as three yuan ethylene propylene and nitrile rubber hose, are basically black.
Q:What is the difference between natural and synthetic rubber?
Synthetic rubber is made by synthetic methods, and different kinds of rubber can be synthesized with different raw materials (monomers).
Q:Does the fuel pipe for automobiles belong to rubber product?
If it is a diesel car, then the high pressure part of the metal pipe only, in the low pressure part of the rubber tube.
Q:Can PVC blend with rubber?
PVC is a high polar polymer, so it has good compatibility with polar rubber,
Q:Several aspects of rubber aging performance and how to identify them
Oxygen, oxygen free radical chain reaction in rubber with rubber molecules, the molecular chain rupture or excessive crosslinking caused by rubber performance. Oxidation is one of the important reasons for aging of rubber
Q:What about rubber molding, foaming and layering?
Foaming1 vulcanization is not sufficient, the temperature is too low or time is too short, so that the volatile compounds produced during curing have not been cleaned out;2, under the pressure of vulcanization, the trapped gas and sulfur volatile matter can not be discharged in time3, there is air or moisture in the glue;4, curing temperature is too high, the surface of the gum material premature vulcanization, hindered the glue material in the steam, air free precipitation5 vulcanization speed of material is too fast
Q:How are rubber wires processed?
In the production of rubber products, vulcanization is the last process.Vulcanization is a crosslinking process in which rubber molecules change from linear structure to network structure under certain conditions. Curing methods are cold vulcanization, room temperature vulcanization and heat vulcanizing three kinds. Most rubber products are vulcanized by heat. Hot vulcanizing equipment, vulcanizing pot, flat vulcanizing machine, etc.. Rubber wires and cables are vulcanized by continuous hot air.
