Description

Thermoplastic elastomer sheet

Technical Field

The invention relates to the technical field of thermoplastic elastomers, in particular to a thermoplastic elastomer sheet.

Background

The thermoplastic elastomer is a high polymer material which can display rubber elasticity at normal temperature and can be plasticized and molded at high temperature, mainly comprises polystyrene thermoplastic elastomer, polyolefin thermoplastic elastomer, polyurethane thermoplastic elastomer, polyester thermoplastic elastomer, polyamide thermoplastic elastomer and the like, and particularly the polyurethane thermoplastic elastomer is widely applied to sheets such as sealing gaskets, oil fields, oceans and exploration cables, hot melt adhesive films, air mattresses, protective films and the like.

The hot melt adhesive film is used as one kind of thermoplastic elastomer sheet, is widely used for decorating the surface of printed matter, and is used for sticking various patterns, embroidered badges, armband, other seals and various woven marks on various clothes, textile fabrics, sponges and non-woven fabrics, and is simple and convenient to operate when in use.

However, the hot melt adhesive film in the current market has poor wear resistance and weather resistance, is easy to fall off and damage, and is not suitable for special working people to use in special environments, such as people who often work in high-temperature environments, but certain garments and products are required to be accompanied by certain logo badges and the like.

Therefore, how to provide a thermoplastic elastomer sheet excellent in various properties is a problem that needs to be solved by those skilled in the art.
