EPDM unvulcanized rubber and waste EPDM rubber products are recycled and reprocessed. EPDM reclaimed rubber has excellent high and low temperature resistance, aging resistance, and electrical insulation. It can be directly substituted or combined with EPDM. Raw rubber is used together to produce various rubber products to achieve the purpose of ensuring quality and reducing costs. In actual production, rubber products in different use occasions have different performance requirements for EPDM reclaimed rubber. Rubber product manufacturers need to further adjust the comprehensive performance of EPDM rubber products according to actual needs.

1. Auto parts

It is understood that rubber parts in automobiles account for 3.5%-8% of the weight of the entire vehicle. In addition to rubber tires, there are a large number of sealing strips, pipelines, shock absorbers, etc., including rubber airbags, radiator hoses, shock absorbers, Heater hoses, car door and window sealing strips, sealing plugs, car light seals, wire joints, etc. will use EPDM reclaimed rubber; the above-mentioned car rubber parts usually use the heat resistance, low temperature resistance, and Weather resistance, ozone resistance, and chemical medium resistance; choose the appropriate EPDM reclaimed rubber, adjust the types and amounts of vulcanizing agents, accelerators, and reinforcing agents in the formula, and further optimize the comprehensive indicators of auto parts.

2. Wire and cable

Rubber wires and cables are cables made of rubber as the insulating layer and sheath. They are generally made of natural rubber, styrene butadiene rubber and ethylene propylene rubber. They not only need to meet the basic insulation performance 2LLYY817 and mechanical strength requirements, but also the rubber material used. The aging resistance and abrasion resistance also have strict requirements. EPDM reclaimed rubber retains the excellent electrical insulation, weather resistance, ozone resistance and heat resistance of EPDM rubber. It can be used to produce various low, medium and high voltage wires and cables, ship cables, etc., or Used in the production of transformer parts, mat insulation parts, electrical seal cabinets, capacitor fillers, etc.

3. Building materials

There are many types of building materials that use rubber as the main raw material. Rubber waterproof materials such as waterstops, waterproof films, watertight concrete, etc., rubber sealing materials such as building seals, gaskets, etc., rubber support shock absorption materials such as bridge supports, damping Earthquake-resistant bearings, etc., as well as rubber paving materials such as gymnasium rubber floors, rubber walkways, rubber asphalt pavements, etc.

Among the many rubber building materials, roof waterproofing membranes, basement and tunnel waterproofing materials, building door and window sealing strips, water-proof materials, rail damping pads, etc. have strict requirements on the water resistance, weather resistance, and chemical resistance of the rubber material. ; EPDM reclaimed rubber has excellent aging resistance (such as weather resistance, ozone resistance), high and low temperature resistance and chemical stability, and can be used to completely or partially replace EPDM in the preparation of building materials. While ensuring quality, the cost of raw materials is significantly reduced.
