The important role of optical PET film-technical knowledge
The important role of optical PET film: direct sales by protective film manufacturers. Release time: 2019-07-17 Click: 1171 1. The raw materials used to synthesize PET need to improve the cleanliness and purity of terephthalic acid and ethylene glycol to meet the requirements of PET film The need for optical performance. 2. Commonly used antimony catalysts will be reduced to elemental antimony during the reaction process, which will make the polyester color gray, including such problems as the optical PET base materials manufactured abroad. Therefore, the research and development efforts in optical polyester catalysts can be improved. 3. The surface cleanliness, impurities, fish eyes, crystal points, scratches and other issues that affect product performance during the manufacturing process of optical PET film require special attention. At present, some domestic manufacturers still need to improve the quality stability of optical film products. Therefore, the equipment operation and process design need the guidance of professional and technical personnel. 4. Few companies have developed the antireflection coating solution for the surface of the optical PET film after stretching. The coating solution not only has better antireflection properties on the surface of the optical film, but also imparts good opening to the film, which plays a very important role. 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!
