EPDM rubber Materials

·EPDM rubber material is a chemical copolymer and belongs to synthetic rubber material.

·The main characteristics of this material are excellent heat resistance, cold resistance, oxidation resistance and electrical insulation performance, as well as excellent physical strength and elastic modulus.

·EPDM is widely used in the manufacture of wires and cables in the fields of industry, automobiles, construction, electrical, and medical.

EPDM, or ethylene propylene diene monomer, is a terpolymer of ethylene, propylene and a non-conjugated diene that has been commercially produced since 1963. It is known for its excellent resistance to oxidation, ozone and corrosion, and belongs to the polyolefin family with excellent vulcanization characteristics. EPDM has the lowest specific gravity of all rubbers and can absorb large amounts of fillers and oils without much impact on its properties, so it can be made into low-cost rubber compounds.

The main performance characteristics of EPDM include

Low density and high filling: EPDM is a low-density rubber that can be filled with oil and fillers in large quantities to reduce costs.

Aging resistance: Excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical properties, oil filling and room temperature fluidity.

Corrosion resistance: Due to the lack of polarity, it has good resistance to various polar chemicals such as alcohols, acids, alkalis, oxidants, refrigerants, detergents, animal and vegetable oils, ketones and fats.

Water vapor resistance: Excellent performance in high-temperature steam without change in appearance.

Resistance to superheated water: closely related to the vulcanization system. The performance of EPDM under certain vulcanization systems changes little after being soaked in superheated water.

Electrical properties: excellent electrical insulation and corona resistance.

Elasticity: no polar substituents in the molecular structure, low molecular cohesive energy, and flexibility.

Adhesion: due to the lack of active groups in the molecular structure, self-adhesion and mutual adhesion are poor.

EPDM is widely used, including seals in the automotive industry, waterproof materials in the construction industry, insulating sleeves and sheath materials for wires and cables, and other rubber products such as rubber tubes, rubber seals, rubber sheets, etc.
