Is the PET release film PET plastic all transparent? -Film supplier
Not all PET film plastics are transparent. Transparent PET is more difficult to make. Dongguan PET film is a milky white or yellowish highly crystalline polymer with a smooth and shiny surface. Creep resistance, fatigue resistance, friction resistance and dimensional stability, low abrasion and high hardness, have the greatest toughness among thermoplastics; good electrical insulation performance, less affected by temperature, but poor corona resistance. Non-toxic, weather resistance, good chemical resistance stability, low water absorption, resistance to weak acids and organic solvents, but not immersed in hot water and alkali. PET resin has a high glass transition temperature, slow crystallization speed, long molding cycle, long molding cycle, large molding shrinkage, poor dimensional stability, crystallization molding is brittle, and low heat resistance. Through the improvement of nucleating agent, crystallization agent and glass fiber reinforcement, PET has the following characteristics in addition to the properties of PBT: 1. The bending strength is 200MPa, the elastic modulus reaches 4000MPa, the creep and fatigue resistance are also very good, the surface hardness is high, and the mechanical properties are similar to those of thermosetting plastics; 2. Since the ethylene glycol used in the production of PET is almost half the price of the butylene glycol used in the production of PBT, PET resin and reinforced PET are the lowest price among engineering plastics and have a high cost performance. 3. The heat distortion temperature and long-term use temperature are the highest among the thermoplastic general engineering plastics; 4. Because of its high heat resistance, the reinforced PET is immersed in a solder bath at 250°C for 10 seconds. It hardly deforms or does not change color. It is especially suitable for the preparation of soldered electronic and electrical parts; therefore, not all PET is white.
