The main raw material of PET film is LLDPE, which is relatively soft and has a certain degree of stretchability. The general thickness is 0.0mm-0.15mm, and its viscosity varies from 5G-500G according to the requirements of use (in terms of viscosity, domestic and foreign divisions are different, such as South Korea 200 grams of the film is equivalent to about 80 grams in the country), the protective film of PE material is divided into electrostatic film, anilox film and so on. Mechanical properties PET film has a high tensile strength, comparable to aluminum foil, 9 times that of HDPE film, and 3 times that of PC and PA films. It has low creep and good fatigue resistance (better than reinforced PC and PA). PA), good abrasion resistance and friction resistance. The mechanical properties of PET are less affected by temperature. Thermal properties The heat resistance of pure PET film is not high, but it is greatly improved after reinforcement. The mechanical properties at 180℃ are better than that of PF laminate. It is the heat-resistant variety of reinforced thermoplastic engineering plastics. The resistance of PET It has good heat aging properties, the brittleness temperature is -70℃, and it still has a certain degree of toughness at -30℃. PET is not easy to burn, and the flame is yellow with dripping. Electrical properties Although PET is a polymer, it has excellent electrical insulation and can still be well maintained at high frequencies. PET has poor corona resistance and cannot be used for high-voltage insulation; electrical insulation is affected by temperature and humidity. The influence of humidity is greater. Environmental performance PET film contains ester bonds and is not resistant to water, acid, and alkali under high temperature and water vapor conditions. PET is stable to organic solvents such as acetone, benzene, toluene, trichloroethane, carbon tetrachloride and oils. , It also has higher resistance to some oxidants such as hydrogen peroxide, sodium hypochlorite and potassium dichromate. It is a company specializing in the production of PET film with multiple functions, such as: transparent PET film, milky white PET film, release PET film, supply of PET motor film, etc. With a wide variety of products, affordable prices, and environmental protection, we provide customers with excellent quality and service based on the service tenet of excellence in production, honesty and trustworthiness in distribution, and warm and thoughtful service. Interested parties welcome to inquire!
