Explain in detail what is the difference between silicone pressure-sensitive adhesive and fluorine release film? Source: Protective film factory direct sales Release time: 2019-11-20 Hits: 3504 Silicone pressure-sensitive adhesives generally refer to pressure-sensitive adhesives with silicone polymers as the main body, or acrylic and silicone modified by silicone polymers Modified rubber type pressure sensitive adhesive. Compared with traditional acrylic pressure-sensitive adhesives and rubber-type pressure-sensitive adhesives, it has excellent chemical resistance, water resistance, oil resistance, solvent resistance, high temperature resistance, low temperature resistance, heat resistance degradation, oxidation degradation resistance and other properties, and it can Glue with a variety of difficult-to-stick materials such as non-surface-treated polyolefin (BOPP, PET, PE, etc.) fluoroplastics, polyimide, and polycarbonate. Based on these characteristics, the application fields of silicone pressure-sensitive adhesives are very wide, especially in the electronics industry, such as electronic die-cutting and tape. In addition, because silicone pressure-sensitive adhesive is more compatible with human skin, it will greatly reduce the pain caused by ordinary tape when the tape is removed. It also has special medical applications, such as preparing painless medical tape and transdermal drug delivery ( Quit smoking patch) and so on. Since the surface energy of silicone is very low, ordinary silicone oil release materials are not suitable for the application of silicone pressure-sensitive adhesives. Therefore, we must use fluorine-based silicone oil to cooperate with silicone pressure-sensitive adhesive. The fluorine silicone oil contains the functional group of the complex C4F9, which makes its surface energy lower than that of organic silicon, so as to achieve the release effect. Foshan Bowei Environmental Protection Material Co., Ltd. is an electronic material supplier with 20 years of experience. It can produce PET film with multiple 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!
