EPDM 3722: Technology and Applications
Technology:
EPDM (Ethylene Propylene Diene Monomer) 3722 is a type of synthetic rubber known for its excellent resistance to heat, oxidation, ozone, and weathering. It is produced through the copolymerization of ethylene, propylene, and a diene component which creates a saturated backbone structure with unsaturated side chains. This unique composition gives EPDM 3722 its superior durability and flexibility.
The production process typically involves:
1. Polymerization: Using catalysts, the monomers (ethylene, propylene, and diene) are polymerized to form the EPDM copolymer.
2. Compounding: The raw polymer is mixed with fillers, plasticizers, and other additives to enhance specific properties.
3. Vulcanization: The compounded EPDM is then cross-linked using sulfur or peroxide curing agents, which improve its elasticity and thermal stability.
Applications:
1. Automotive Industry: EPDM 3722 is widely used in the automotive sector for manufacturing weather seals, hoses, belts, and gaskets due to its resistance to heat and oxidation. Its flexibility and durability under various weather conditions make it ideal for use in vehicle door seals, trunk seals, and window seals.
