EPDM manufacturersTo tell you, EPDM is synthesized with ethylene and propylene as the main raw materials, and has anti-aging, electrical insulation, and ozone resistance.EPDM manufacturersTell you, it can be filled with a lot of oil and carbon black, the product price is low, the chemical stability is good, the abrasion resistance, elasticity, oil resistance and styrene butadiene rubber are close. As a tire side, and inner tube and auto parts are widely used, can be used as wire, cable sheath and high voltage and ultra high voltage insulation materials. Can also make shoes, health supplies and other light-colored products.EPDM manufacturersTell you what, function and improvement?

1. Low density and high filling

The density of ethylene propylene is the density of 0.87. Coupled with a large number of filling oil and filler, can reduce the cost of the product, to make up for the high price of ethylene propylene rubber shortcomings, for high GOMENIY value of ethylene propylene, high filling after the reduction of physical mechanical energy is not large.

2. Aging resistance

EPDM rubber has good resistance to days, ozone, heat resistance, acid and alkali resistance, water and steam resistance, color stability, electrical properties, filling oil and normal temperature fluidity. Ethyl propylene products can be used in the 120 for a long time, in the 150~200 can be used for a short time or intermittent. The use temperature can be increased by adding appropriate anti-aging agents. Triple B crossed with peroxide can be used under harsh conditions. Ternary ethylene will not crack for more than 150h under the conditions of ozone concentration of 50pphm and tensile strength of 30%.

3. Corrosion resistance

Lack of polarity and low saturation, so it has good tolerance to alcohol, acid, alkali, oxidant, refrigerant, detergent, animal and vegetable oil, ketone, fat and other polar chemicals. However, in aliphatic and aromatic solvents (such as gasoline, benzene, etc.) and mineral oil, the stability is poor. Skills will also decline due to the long-term effects of agricultural products. ISO/TO 7620 is a collection of about 400 kinds of corrosive gases and liquid chemicals on the impact of various characteristics of the data, the provisions of 1~4 show the degree of its role, the impact of corrosive chemicals on performance.

4. Water resistance to steam

Presumably, the inner water vapor is better than the heat resistance. In 230 superheated steam, close to 100h, the appearance remains unchanged. Under the same conditions, the appearance was significantly deteriorated in a short period of time.

5. Hot water resistance

Hot water tolerance is also very good, but it is closely related to all vulcanization systems. After soaking in 125 superheated water for 15 months with disulfide and TMTD as vulcanization system, the mechanical properties changed little and the volume expansion rate was only 0.3%.

6. Electrical characteristics

It has good electrical insulation properties and new crown resistance, and its electrical function is better than or close to styrene-butadiene rubber, chlorosulfonated polyethylene, polyethylene and cross-linked polyethylene.

7. Elasticity

In the molecular structure, due to the non-polar substituents, the molecular cohesion is low, and the molecular chain can maintain elasticity in a large range, and it can be maintained at low temperatures second only to natural discussion and butadiene rubber.

8. Adhesion

Lack of active groups in the molecular structure, low cohesion, easy to add adhesive, self-viscosity and mutual viscosity difference.
