What is the specific difference between fluorine release film and silicone oil film? Source: Protective film factory direct sales Release time: 2019-05-28 Hits: 1732 First of all fluorine release film is made of polyester film, coated with fluorine plastic release agent, and laminated Silicone pressure sensitive adhesive. Suitable for high-temperature silicone pressure-sensitive adhesive tape composite die-cutting type, easy to peel off after use. According to Coating Online, after attaching the tape, the adhesive force of the tape can maintain about 95% of the original. It is widely used in the adhesive production process of PI, green high-temperature tape production, silicone double-sided tape die-cutting, thermal silica gel casting and other industrial products. Secondly, PET silicone oil film is abbreviated as silicone oil film, also known as PET release film, which is to coat a layer of silicone oil on the surface of the PET film to reduce the adhesion of the PET film surface to achieve the release effect. It can be divided into single-sided release film and double-sided release film; according to the release force, it can be divided into light release film, medium release film, and heavy release film. PET release film has been widely used in packaging, printing, circuit boards, laser anti-counterfeiting, laminating, electronics, sealing material film, reflective materials, waterproof materials, medicine (plaster paper), sanitary paper, adhesive products , Die-cutting and punching processing industries. If we get these two materials, how can we distinguish them? In fact, on the surface, there is no difference between the fluorine release film and the silicone oil film. The appearance is almost difficult to distinguish, so I want to understand the two materials. The difference can be analyzed by the following points: 1. The fluorine release film will not react to the silicone rubber surface, and the release force is stable; the silicone oil film will react and cannot be peeled off; 2. The price distinction: fluorine The price of the original release film is relatively high, while the silicone oil film is relatively low; 3. MY-2G is used for the release force test of the fluorine film, and the TESA7475 is used for the release force test of the silicone oil film (for specific test procedures, please refer to the standard provided by the manufacturer); 4. In the choice of die-cutting materials: Generally, silicone tape is matched with fluorine film, while acrylic tape is matched with silicone oil film. Of course, the materials selected for different products will be different. Foshan Bowei Environmental Protection Material Co., Ltd. is a supplier of electronic materials with 10 experiences. 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, etc. Interested parties welcome to inquire!
