The specific description of the product under investigation is as follows:
ㅇ Scope of investigation: imported EPDM rubber originating in the United States, South Korea and the European Union.
ㅇ Product name under investigation: EPDM rubber.
ㅇ English name: Ethylene-Propylene-non-conjugated Diene Rubber or Ethylene Propylene Diene Monomer (EPDM)
Physical and chemical properties: EPDM rubber is a terpolymer of ethylene, propylene and non-conjugated diene. It has a white or slightly yellow solid appearance at room temperature and is easy to mix. The physical properties, chemical characteristics and processing properties of EPDM rubber are mainly different due to the molecular structure of the polymer, and the factors related to the molecular structure include the third monomer type, Mooney viscosity and oil-extended content. . EPDM rubber has good aging resistance, chemical resistance, low temperature resistance and dielectric properties.
Main use: EPDM rubber has a wide range of uses, and can be used in construction, wire and cable, automobile industry, transportation and other fields. In terms of construction, it is mainly used for roof single-layer waterproofing membranes, etc.; in terms of wire and cable, it is mainly used for power input lines of civil and commercial buildings, cables for construction machinery, cables for mining, cables for nuclear power plants, automotive ignition wires, control and signals Cables, etc.; in the automotive industry, they are mainly used for non-tire parts of automobiles, trucks and buses, including automobile water tanks and heat-resistant hoses, sealing strips, rubber bands, body and chassis parts, rain strips, bottom plates and ring tubes, etc. ; In traffic, it is mainly used in vehicle door and window sealing strips, shock absorption, waterstop, etc.
This product is listed in the "Import and Export Tariff of the People's Republic of China": 40027010 and 40027090.
