Description

Technical Field

[0001] The present application relates to the technical field of rubber processing, and in particular to a cutting device for processing EPDM sound insulation rubber. Background Art

[0002] EPDM rubber is a high-tech environmentally friendly material. It is a terpolymer of ethylene, propylene and non-conjugated dienes. It is a type of ethylene-propylene rubber, also called terpolymer EPDM. It is mostly used in plastic tracks, kindergarten playgrounds, sports venues and other leisure places. Because its main chain is composed of chemically stable saturated hydrocarbons and only contains unsaturated double bonds in the side chains, it has excellent ozone resistance, heat resistance, weather resistance and aging resistance. It can be widely used in automotive parts, waterproof materials for construction, wire and cable sheaths, heat-resistant hoses, tapes, automotive seals and other fields. However, in the processing of EPDM rubber, cutting is often required.
