Analysis of what is the source of synthetic PET film: protective film factory direct sales Release time: 2019-12-30 Click: 14144 The main raw materials of synthetic PET are: terephthalic acid (TPA), dimethyl terephthalate (DMT), Ethylene glycol (EG). The catalysts are mainly metal compounds, such as antimony-based catalysts, germanium-based catalysts, and titanium-based catalysts. Among them, antimony-based catalysts are most widely used due to their high activity, few side reactions, low degree of promotion of the thermal degradation reaction of polyester, low price, and high-quality products. Commonly used antimony catalysts are ethylene glycol antimony, antimony acetate and antimony trioxide. However, the toxicity of antimony compounds will have adverse effects on human health and the environment. In recent years, countries around the world have put forward some new requirements for the use of antimony. . Foshan Bowei Environmental Protection Material Co., Ltd. is an electronic material supplier with 20 years of experience. It can produce PET film with various functions, such as: sub-(matte) PET film, flame-retardant (fire-resistant) PET film, inkjet printing Film, anti-static PET film, anti-fog PET film, anti-UV PET film, non-shrinking PET film, PET release film, optical PET film, etc. Interested parties welcome to inquire!
