The main problems of optical PET film: Source: Protective film factory direct sales Release time: 2019-07-22 Hits: 2882 1. The carrier base film used is non-optical and not suitable for optical non-destructive testing: in some areas that require high-precision non-destructive testing , PET release film needs to be attached on both sides of the polarizer, which has very strict requirements on the optical performance of PET release film. The film used in ordinary release film has low optical performance requirements, low light transmittance, and fog. Neither degree nor clarity can meet the needs of optical non-destructive testing, so the production of the release film is none other than optical PET film. 2. Research on the surface/interface of silicone and carrier film has little attention, and the phenomenon of 'silicon drop' appears from time to time: in some application fields with strict requirements, it is necessary to remove the silicone release film with low or no residue. Therefore, the silicone Both have extremely high requirements with carrier films, but the surface/interface research of silicone and carrier films has received little attention. 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!
