The release film can adhere to the prepreg, but also easy to separate the two, has enough compactness, can prevent moisture through it into prepreg, not easy to produce chemical reaction, good temperature resistance and humidity resistance, moistureproof, oil proof, play the role of product isolation.

The separated film is divided into PE and PET film

PE film is polyethylene plastic, stable chemical properties, usually made food bags and various containers, acid, alkali and salt water solution erosion, but should not be cleaned or soaked with strong alkaline detergent.

PE membrane is divided into high density, low density and linear PE, the most widely used is to make all kinds of plastic film and plastic cloth

Characteristic：

Corrosion resistance, electrical insulation (especially high-frequency insulation) can be excellent, chlorination, irradiation modification, use of glass fiber reinforced polyethylene, melting point, hardness and rigidity, high strength, low water absorption, good electrical properties and radiation resistance; soft, high pressure polyethylene elongation, impact strength and good permeability; ultra high molecular weight polyethylene high impact strength, fatigue resistance, wear resistance, suitable for the production of low pressure polyethylene corrosion resistant parts and parts of high pressure polyethylene insulation; suitable for making films; ultra high molecular weight polyethylene is suitable for production of shock, abrasion and transmission parts.

The PE film can be divided into transparent PE film, blue PE film, yellow PE film, black PE film, white PE film and so on

The commonly used thickness is 0.03mm, 0.06mm, 0.125mm and so on

Application areas: isolation, filling, protection, easy peeling and so on

PET release film, also called PET silicone oil film, is coated with a layer of silicone oil on the surface of PET film, in order to reduce the adhesion of PET film surface and achieve the effect of separation. It can be divided into single side film and double side film.

The PET film can be divided into transparent PET film, blue PET film, yellow PET film, black PET film, white PET film, and white PET film

According to the detachment force zone separation membrane: light PET release membrane (3-5 grams detachment force), medium PET release membrane (6-10 grams detachment force) and heavy PET release membrane (10-15 grams)

The commonly used thickness: 0.012mm, 0.019mm, 0.025mm, 0.038mm, 0.05mm, 0.075mm, 0.1mm, 0.125mm, 0.188mm, PET film has been widely used in packaging, printing, screen printing, printing, nameplate, membrane switch, flexible circuit, insulation products, circuit board, laser anti-counterfeiting, laminating, electronics, sealing material film, reflective material, waterproof material, medicine (plaster paper), toilet paper, adhesive products, die-cutting processing and other industries.
