Factory Rubber Extrusion EPDM Silicone Sealing Strip Rubber Strip

1. Low density and high filling capacity. Ethylene propylene rubber is a lower density type of rubber.
2. Aging resistance: Ethylene propylene rubber has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical properties, oil filling and normal temperature fluidity. Ethylene-propylene rubber products can be used at 120°C for long periods of time and at 150-200°C for short-term or intermittent use. Adding appropriate antioxidants can increase the temperature at which it can be used. Peroxide cross-linked EPDM rubber can be used in harsh conditions. EPDM rubber can last for more than 150 hours without cracking under the conditions of ozone concentration of 50pphm and stretching of 30%.
3. Corrosion resistance: Because ethylene propylene rubber lacks polarity and has low unsaturation, it has good resistance to various polar chemicals such as alcohols, acids, alkalis, oxidants, refrigerants, detergents, animal and vegetable oils, ketones, and greases. Corrosion resistance;
4. Water vapor resistance: Ethylene propylene rubber has excellent water vapor resistance, which is estimated to be better than its heat resistance. In superheated steam at 230°C, there is no change in appearance after nearly 100 hours. However, under the same conditions, the appearance of fluororubber, silicone rubber, fluorosilicone rubber, butyl rubber, rubber and natural rubber will deteriorate significantly in a short period of time.
5. Elasticity: Since there are no polar substituents in the molecular structure of ethylene-propylene rubber, the cohesive energy of the molecule is low, and the molecular chain can remain flexible in a wide range, second only to natural rubber and butadiene rubber, and can still maintain flexibility. at low temperatures.
