What are the essential differences between the functions of PET protective film and PET release film.
PET protective film
PET protective film is prepared by basically sizing the original film with a layer of chemically cross-linked polyacrylic acid emulsion as the adhesive, and adding several kinds of unique modifiers. The glue has no color and is transparent. It is soft, sticky and heat-resistant. It can be used to maintain the surface of different raw materials in a wide range of applications.
PET alias film heat-resistant polyester film. It has excellent process performance, organic chemical characteristics and specification reliability, light transmittance, recyclability, and can be widely used in magnetic recording, light-sensitive profiles, electronic devices, electrical equipment insulation layer, industrial grade film, packaging and decoration design and other industries. Features: good aging resistance, high temperature resistance of 100-150 ℃, good strength and leveling.
PET release film
PET release film is a raw material for industrial production, also called methyl silicone oil film. Because of its strong adsorption capacity, it is often used for anti-static. The wall or material is PET, and the thickness ranges from 25um to 150um.
Characteristics of PET release film:
1. Good reliability, smooth surface, no color transfer, no scratches, no particles and other defects
2. Manufactured in the 1000 level purification workshop, with high cleanliness
3. Environmental protection of materials, low electrostatic induction, moderate strength and good flexibility
4. Uniform sizing, reliable release force
PET release film has the characteristics of high definition, non-toxic and odorless, high tensile strength, good stiffness, resistance to burning and cracking, not easy to damage, excellent electrical equipment and electronic optical characteristics, good oxygen barrier tube and moisture resistance, low temperature resistance (-- 70 ℃), high temperature resistance (+200 ℃), corrosion resistance and stable folding.
