What is EPDM Reclaimed Rubber? EPDM reclaimed rubber is rubber obtained by desulfurizing EPDM scrap, including EPDM head rubber, uncured EPDM rubber, or waste EPDM rubber products. It retains the basic performance characteristics of EPDM rubber, being resistant to high and low temperatures, ozone, and weathering. It can be used alone or together with EPDM rubber or butyl rubber to produce rubber products, reducing raw material costs.
Which rubber products can use EPDM reclaimed rubber in production? In actual production, the main role of EPDM reclaimed rubber is to replace high-priced EPDM raw rubber and reduce the production cost of EPDM rubber products. Therefore, within allowable performance limits, most EPDM rubber products can use EPDM reclaimed rubber in appropriate amounts.
1. Applications of EPDM Reclaimed Rubber in the Automotive Industry
EPDM rubber has excellent aging resistance. Automotive door and window seals, radiator hoses, chassis components, rubber mats, dust covers, and other parts are primarily processed using EPDM rubber. Using EPDM reclaimed rubber in appropriate amounts can effectively reduce raw material costs while ensuring product performance and improve rubber processing performance. EPDM reclaimed rubber can also be mixed in small amounts with butyl inner tubes to improve cracking and heat generation issues in pure butyl inner tubes.
2. Applications of EPDM Reclaimed Rubber in Building Construction
EPDM reclaimed rubber is widely used in construction, mainly including building door and window seals, pipe seals, dust covers for doors and windows, rubber waterproof membranes, water stops, heat-resistant rubber sheets, and rubber joints. It can be used alone or combined with EPDM rubber, reducing raw material costs by 20%-30% while maintaining the basic properties of EPDM rubber, such as resistance to high and low temperatures, ozone, weathering, chemical corrosion, aging, and high insulation.
3. Applications of EPDM Reclaimed Rubber in Electronics and Electricals
EPDM reclaimed rubber retains EPDM rubber's ozone resistance, weatherability, and insulation properties. It can partially replace raw rubber in non-high-voltage critical insulation parts. By selecting EPDM reclaimed rubber with high rubber content, low impurities, and stable composition, raw material costs can be reduced. Common applications in electronics and electricals include wire and cable jackets, cable sheaths, insulating rubber sheets, and electrical seals.
4. Applications of EPDM Reclaimed Rubber in Heat-Resistant Rubber
EPDM reclaimed rubber has excellent high-temperature resistance and can completely or partially replace EPDM rubber in producing heat-resistant rubber products, such as heat-resistant rubber sheets, heat-resistant conveyor belts, heat-resistant hoses, and heat-resistant sealing rings. When producing rubber products with strict heat resistance requirements using EPDM reclaimed rubber, it is best not to use reclaimed EPDM entirely; it can be mixed with some EPDM rubber and should avoid extensive mixing with polar rubbers.
EPDM reclaimed rubber can also be used in sports facilities and household products.
Premium eco-friendly EPDM reclaimed rubber primarily uses imported EPDM head rubber as the main raw material. It has physical properties such as high- and low-temperature resistance, aging resistance, high insulation, ozone resistance, and corrosion resistance (E5LYY114). Compared with EPDM reclaimed sealing strips, it also features high rubber content, odorless, good elasticity, smooth and shiny product surfaces, making it an ideal material to reduce costs in the production of extruded EPDM products. It can be used in the production of insulation materials, EPDM sealing strip hoses, wire and cable jackets, water stops, air-conditioning pipes, conveyor belts, sports facilities, and anti-corrosion linings.
