Problems in the synthesis of raw materials for optical PET film manufacturing-technical knowledge

Source of problems in the synthesis of raw materials for optical PET film manufacturing: direct sales by protective film manufacturers Release time: 2019-07-16 Hits: 1636 Optical BOPET film is made of special materials for optical film synthesis, film stretching, surface coating, etc. The raw material synthesis is the basis for the manufacture of optical grade PET film. The traditional bright PET slices cannot meet the manufacturing requirements of optical grade PET film due to differences in hue, crystallinity and optical properties, so they need to be modified. , Replacing the catalyst and other treatments. At the same time, the quality of the basic raw materials of terephthalic acid and ethylene glycol also needs to be strictly controlled to reduce the impurity content. 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!
