Characteristics and advantages of PET plastic
Good mechanical properties: flexural strength 200MPa, elastic modulus above 4000MPa, creep and fatigue resistance is also very good, high surface hardness, mechanical properties are similar to thermosetting plastics.
Good heat resistance: thermoplastic general engineering plastics have the highest heat deflection temperature and long-term use temperature. Reinforced PET is soaked in a solder bath at 250°C for 10 seconds with little distortion or discoloration. It is particularly suitable for the preparation of electronic and electrical components for soldering.
Cost-effective: Because ethylene glycol used in PET production is almost half as cheap as butylene glycol used in PBT production, PET resin and reinforced PET are the lowest among engineering plastics and are cost-effective.
PET plastic has excellent heat resistance, weather resistance, electrical properties, rigidity and strength, and its reinforcement, flame retardant modification and alloying modification can significantly improve its heat resistance, modulus, toughness, dimensional stability and flame retardancy. CY, widely used in electronic appliances, automobiles and household appliances and other fields.
The application of PET plastic in different fields
Packaging field: from carbonated beverages to beer bottles, edible oil bottles, condiment bottles, medicine bottles, cosmetic bottles, etc.
Film sheet field: all kinds of food, medicine, non-toxic, sterile packaging materials; High-grade packaging materials for textiles, precision instruments and electronic components; Audio tapes, video tapes, films, computer floppy disks, metal coatings, photosensitive film substrates; Electronic and mechanical in the field of electronic ternary insulation, capacitor films, flexible printed circuit boards and film switches.
Auto parts field: such as power distribution board cover, ignition coil, various valves, exhaust parts, distribution cover, measuring instrument cover, small motor cover, etc., PET excellent coating, surface gloss and rigidity, automotive exterior parts.
Electrical and electronic fields: manufacturing connectors, coil windings, integrated circuit housings, capacitor housings, transformer housings, TV accessories, tuners, switches, timer housings, automatic fuses, motor brackets and relays.
Mechanical equipment: manufacturing gears, cams, pump casings, pulleys, motor frames and clock parts, can also be used as microwave oven baking pans, various ceilings, outdoor billboards and models.
