Characteristics and functions of EPDM sealing strips How to distinguish EPDM sealing strips?
EPDM rubber sealing strip is an organic synthetic material with good product performance and quality, which is very common in life and production. What are the characteristics and functions of EPDM sealing strip? Let's have a look!

Characteristics of EPDM rubber sealing strip

First, its main raw material is olefinic organic matter, so its chemical stability is better. It has low density and good filling effect. Its density is less than that of water, and it is suitable for filling material, so it can be used as sealing strip. It can be concluded that it should have a good sealing effect when used as a sealing strip.

Second, good aging resistance, which is very important for sealing strips, because sealing strips are rarely replaced frequently, good oxidation resistance helps to improve service life, and can ensure good sealing effect after long-term use.

Third, the anti-corrosion effect is good, which is not very useful in life, but it is quite practical if it is used in chemical plants or hospitals.

Fourth, the waterproof effect is obvious and the hydrophobicity is strong.

Fifth, the forms are diversified, and different product shapes are applicable to many aspects, which can meet the needs of customers with different purposes.

Sixth, good shock absorption and anti-skid performance.

Seven, corrosion resistance, not easy to aging deformation, even in high temperature environment aging phenomenon will not endanger human health.

Function of EPDM sealing strip

EPDM has a wide range of uses, mainly used in housing construction, wire and cable, automobile industry and other fields. In building construction, it is mainly used for single-layer waterproofing membrane on the roof; In terms of wires and cables, they are mainly used for input wires of civil and commercial buildings, construction wires, mining cables, nuclear power plant wires, vehicle front points, control and signal cables, etc.

In the car industry, EPDM rubber strips are mainly used for tire and non-tire parts of cars, trucks and buses, including water tanks, heating hoses, sealing strips, rubber belts, body and chassis parts, rain strips, bottom plates and annular pipes.

How to distinguish EPDM sealing strip

1, color observation, that is, carefully observe the color of the rubber body,

Many counterfeiters use low-end inferior rubber, so the produced spheres are often particularly dark in color. 2, taste is actually the best way to judge, because the composition of rubber contains olefins, so rubber will have a pungent smell that normal people feel. But EPDM is ethylene, not aromatic. So as long as users pay attention, it is not difficult to judge the real good goods.

3. Touch, that is, if you rub the inner layer of rubber body carefully, it will feel very smooth. Because the authentic EPDM rubber is excellent in texture and expensive, the produced rubber soft joint feels particularly smooth.

This paper introduces the characteristics and functions of EPDM sealing strip, hoping to help everyone.
