Thermoplastic elastomer, sometimes called thermoplastic rubber, is a class of copolymer or blend with properties of both thermoplastic and elastomer. The molecular structure can be vividly divided into a hard segment (crystallized at room temperature) and a soft segment. Thermoplastic elastomer has the following characteristics: wide hardness range (Shore 0A-80D), good touch; The diversity of molecular structure facilitates functional design; Diversified processing methods; Waste material can be recycled; Small specific gravity, no obvious creep; Good environmental protection. This paper introduces the structure, properties and applications of common thermoplastic elastomers TPS, TPV, TPU and TPEE, and compares their appearance, hand feel, chemical resist

TPV preparation methods are usually three, namely dynamic vulcanization method, physical blending method, latex blending method. The ultimate purpose of the three methods is to obtain the classic "sea-island" structure of TPV. Dynamic vulcanization technology has undergone a long period of evolution, from the early open smelter process to the close smelter process, until the twin-screw continuous vulcanization manufacturing technology. At present, dynamic vulcanization method is widely used in TPV production enterprises at home and abroad, but few enterprises use physical blending method to produce TPV。

Car trunk mat is a collection of water absorption, dust, decontamination, sound insulation, protection of the rear box carpet five main functions as one of an environmental protection automotive interior parts. With the development of domestic economy, consumers pay more and more attention to their own health, and the environmental protection requirements of automotive interior materials are higher and higher. Some PVC products have been banned in Europe and the United States, PVC car foot trunk pad is gradually abandoned by foreign car owners, instead choose to use more safe and healthy TPV material trunk pad; The progress of science and technology has made automobile manufacturers put forward higher requirements for car parts. The above reasons, all make safe and healthy TPV car trunk mat more and more popular in the market.
