Introduction Of Chemical Properties Of Polyester Film

Aug 31, 2017

    Polyester film is a polymer plastic film, because of its comprehensive performance is more and more favored by the vast number of consumers. Because the production and technical level of our country still can not meet the demand of the market, some still need to rely on imports. The price of polyester film is higher, the thickness is generally 0.012mm, commonly used to cook the outer layer of packaging materials, printing is better. Because of the complexity of polyester film and difficult to judge, to the customs supervision brings many difficulties.Polyester Film

    Usually colorless transparent, shiny film (now added additive particles to make it color), excellent mechanical properties, rigidity, hardness and toughness, puncture resistance, friction resistance, high temperature and low temperature, chemical resistance, oil resistance, gas tightness and Paushan are good, which are commonly used as one of the permeable composite film substrates, but the corona resistance is not good.Polyester Film

   The role of polyester film is in electrical equipment to separate the electric potential of the electric part, so insulation material should first have a high insulation and voltage strength, and can avoid leakage, breakdown and other accidents. Second, heat resistance is better, avoid overheating and aging deterioration: In addition, there should be good thermal conductivity, moisture resistance and high mechanical strength and processing convenience.Polyester Film

   Polyester film is the packaging industry, essential packaging raw materials, dust-proof, windproof, moistureproof and other functions, can be very good protection inside the product, and its wide application. Polyester film is a solid insulating material can be divided into inorganic and organic two broad categories. Polyester Film

   Inorganic solid insulating materials mainly, mica and mica products, glass, glass fiber and its products, as well as porcelain, alumina film and so on. They are resistant to high temperature, not easy to aging, with considerable mechanical strength, some of the materials such as, such as low cost, in the application occupies a certain position. The disadvantage of inorganic solid insulating material is that the processing performance is poor and it is difficult to adapt to the requirements of insulating materials.Polyester Film
