Product Description

Our company uses ternary ethylene rubber as the main raw material and various additives through reasonable formulas, strict production processes, and advanced microwave vulcanization equipment to produce chemically cross-linked products. It is a pure rubber material. It has various excellent properties of rubber, such as low compression deformation, good low tenderness and softness, high tear resistance, good wear resistance, excellent oil or solvent swelling resistance, excellent UV resistance and aging resistance. It is a very good sealing material. It is suitable for use with various doors and windows. A dense composite sealing strip made of EPDM rubber sponge suitable for the vast geographical characteristics of China, suitable for temperatures ranging from -60 ºC to 150 ºC. This type of product is mainly used for dynamic and static sealing of doors and windows in automobiles, trains, airplanes, ships, and high-rise buildings.

The main chain in the molecular structure of EPDM rubber does not contain double bonds, so its ozone resistance and antioxidant properties are superior. It can be used for a long time in natural environments with light, humidity, and cold, and has superior weather resistance. Due to the saturated structure of the main chain, it has excellent high-temperature resistance and can be used for a long time at 120 ºC. Its high operating temperature is 150 ºC, and its glass transition temperature is between -35 ºC and -65 ºC. Most vulcanized products are still soft at -50 ºC, so they still have flexibility and low compression deformation at low temperatures. Therefore, they still have good sealing performance at low temperatures and are easy to apply in winter. It is resistant to various polar solutes, including brake oil, acids, alkali alcohols, etc. It has poor resistance to non-polar solutes, such as hydrocarbon solutes like gasoline. Suitable for use in high temperature, cold, coastal, and areas with strong ultraviolet radiation.
Excellent insulation function, low thermal conductivity, and good low-temperature rebound.

Elongation at break
The fracture elongation range of TPE is wide, generally between 200 and 1500%. The elongation at break refers to the percentage of elongation produced by a material when stretched to fracture compared to its original length, and is an important parameter for measuring the flexibility of TPE materials. High elongation at break means that materials can undergo significant deformation under external forces without easily breaking, which is particularly important for applications that require high flexibility and elasticity.
