Description

technical field

[0001] The invention relates to the technical field of TPV materials, in particular to a TPV material for a blow molding grade dust cover and a preparation method thereof. Background technique

[0002] TPV is the abbreviation of Thermoplastic Vulcanizate. The Chinese name is thermoplastic EPDM dynamic vulcanized elastomer or thermoplastic EPDM dynamic vulcanized rubber. It is a polymer composed of highly vulcanized EPDM particles dispersed in continuous polypropylene PP phase. Elastomer material. The physical properties and functions of TPV at room temperature are similar to those of thermosetting rubber. At high temperatures, they behave like thermoplastics, and can be processed quickly, economically and conveniently. TPV thermoplastic EPDM dynamically vulcanized elastomer The vulcanized rubber material is dynamically vulcanized so that EPDM is dispersed in the polypropylene PP plastic matrix with particles less than 2 microns in size, and the characteristi...
