It has good mechanical properties, with an impact strength 3-5 times that of other films, and good bending resistance.2. Resistant to oil, fat, enoic acid, dilute alkali, and most solvents.3. It has excellent resistance to high and low temperatures, and can be used for a long time within the temperature range of 120 ℃. It can withstand high temperatures of 150 ℃ and low temperatures of -70 ℃ for short-term use, and has little impact on its mechanical properties at high and low temperatures.4. Low permeability of gas and water vapor, with excellent gas resistance, water, oil, and odor resistance.5. High transparency, can block ultraviolet rays, and has good glossiness.6. It is non-toxic, odorless, and has good hygiene and safety, and can be directly used for food packagingCharacteristics of DuPont PET plastic raw materials in the United States:PET is a milky white or pre yellow highly crystalline polymer with a smooth and shiny surface. Creep resistance, fatigue resistance, wear resistance, and dimensional stability are good, with low wear and high hardness. It has the greatest toughness among thermoplastic materials: good electrical insulation performance, less affected by temperature, but poor corona resistance. Non toxic, weather resistant, stable against chemicals, low water absorption, resistant to weak acids and organic solvents, but not resistant to hot water immersion or alkali.PET resin has a high glass transition temperature, slow crystallization rate, long molding cycle, long molding cycle, high molding shrinkage rate, poor dimensional stability, brittle crystallization molding, and low heat resistance.Through the improvement of nucleating agents, crystallization agents, and glass fiber reinforcement, PET not only possesses the properties of PBT, but also has the following characteristics.1. The thermal deformation temperature and long-term use temperature are the highest among thermoplastic general engineering plastics2. Due to its high heat resistance, reinforced PET is immersed in a soldering bath at 250 ℃ for 10 seconds without deformation or discoloration, making it particularly suitable for preparing electronic and electrical parts for soldering:3. The bending strength is 200MPa, the elastic modulus reaches 4000MPa, and the creep and fatigue resistance are also good. The surface hardness is high, and the mechanical properties are similar to those of thermosetting plastics.4. Due to the fact that ethylene glycol used in the production of PET is almost half cheaper than butanediol used in the production of PBT, PET resin and reinforced PET are the lowest priced engineering plastics with high cost-effectivenessPET,美國杜邦,953 NC010,PET美國杜邦,美國杜邦953 NC01
