Because the characteristics of the polyester film determines its different uses. Different uses of polyester film and processing requirements raw materials and additives have different requirements, its thickness and technical indicators are not the same; in addition, it has a variety of uses only BOPET, so depending on the use classification of films are BOPET. It can be divided into the following categories: 1, electrical insulation film. Because of its excellent electrical, mechanical, thermal and chemical inertness, good insulation, fight through high voltage, dedicated to electronic, electrical insulating material blue polyester film, a common standard thickness: 25μm, 36μm, 40μm, 48μm, 50μm , 70μm, 75μm, 80μm, 100μm and 125μm (microns). These include wire and cable insulation film (thickness 25-75μm) and touch switch insulating film (50-75μm). Polyester film is a polymer plastic film offer pet polyester film, because of its excellent overall performance and more and more consumers of all ages. Since our production capacity and technological level still can not meet the market demand, some still rely on imports. 2 Properties editor is usually colorless and transparent, glossy film (now available additives particles to have color), excellent mechanical properties, rigidity, hardness and high toughness polyester film, polyester film proportion puncture resistance, abrasion, high temperature and low temperature resistance, chemical resistance, oil resistance, air tightness and preserving flavor is good, it is commonly used barrier film substrate composite, corona resistance. pet polyester film polyester film _ quote _ co Xinda Paper provided by Xiong together Xinda Paper Products Factory.
