Performance and Improvement of EPDM fubber seal strips

(Summary description)The density of EPDM fubber seal strips is a lower rubber, its density is 0.87, and it can be filled with oil and filler. Therefore, the cost of rubber products can be reduced, making up for the disadvantage of high price of ethylene-propylene rubber raw rubber.

Information

  1. Low density and high filling

  The density of EPDM fubber seal strips is a lower rubber, its density is 0.87, and it can be filled with oil and filler. Therefore, the cost of rubber products can be reduced, making up for the disadvantage of high price of ethylene-propylene rubber raw rubber.

  2. Aging resistance

  The EPDM fubber seal strips 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. use. It can be used for a short time or intermittently at 150-200℃, and the use temperature can be increased by adding suitable antioxidant.

  3. Water vapor resistance

  The EPDM fubber seal strips has excellent water vapor resistance and is estimated to be better than its heat resistance. In superheated steam at 230 ° C, the appearance does not change after nearly 100 hours.

  4. Resistance to overheated water

  EPDM rubber seals also have better resistance to superheated water, but are closely related to all vulcanization systems. Ethylene-propylene rubber with dimorpholine disulfide and TMTD as the vulcanization system was soaked in superheated water at 125°C for 15 months.

  5. Electrical properties

  EPDM rubber seals have excellent electrical insulation properties and corona resistance. The electrical properties are better than or close to styrene-butadiene rubber, chlorosulfonated polyethylene, polyethylene and cross-linked polyethylene.

  6. Adhesion

  Due to the lack of active groups in the molecular structure, the EPDM fubber seal strips has low cohesive energy. In addition, the rubber is easy to be frosted, and the self-adhesion and mutual adhesion are very poor.
