Description

technical field

[0001] The invention relates to superfine fibers and a preparation method and application thereof, in particular to a EPDM superfine fiber and a preparation method and application thereof. Background technique

[0002] EPDM has become the third largest synthetic rubber material. Compared with other general-purpose rubbers, it has excellent weather resistance, ozone resistance, heat resistance, good electrical insulation and chemical medium corrosion resistance, and relative density Low, hygienic, most of them present good colorless and transparent characteristics. At present, in the domestic market, it is mainly used in auto parts, building materials, wires and cables, polyolefin plastic modification and oil additives, etc. Other fields include railway transportation, subway engineering, pipeline transportation, drinking water seals, hot water pipes, baby products, etc. The importance of EPDM rubber in the development of new products is increasingly apparen...
