Pet engineering plastic materials (Motor Tests) is the most important variety of thermoplastic polyester. It is a cream or light yellow highly crystalline polymer with high rigidity, low creep, high mechanical strength, good heat resistance, fatigue resistance, abrasion resistance and dimensional stability, small wear and high hardness. Good electrical insulation performance, and other characteristics. PET plastic enhancement, flame retardant modification or alloying modification, can improve its heat resistance, modulus, toughness, dimensional stability and flame retardant properties, such as enhanced toughening level, enhanced low warping level, enhanced flame retardant, low warping enhanced flame retardant, color stability enhanced flame retardant, high light enhanced flame retardant, halogen-free flame retardant series. Modified PET plastics are widely used in electronic and electrical industry, automobile industry and household appliances. Common modified PET has the following four types:
1. Enhanced PET
Enhance the level of PET plastic is filled in PET mineral, increase its rigidity and toughness, and heat resistance, static electricity, etc, to enhance level PET has high mechanical performance is excellent, good dimensional stability, heat resistance, good surface gloss and color stability is good wait for a characteristic, is mainly used in automobile air-conditioning outlet, the oven handle, bearings, electrical home appliances shell, etc.
2. Glass fiber reinforced PET
Glass fiber reinforced thermoplastic polymer as an important way of engineering plastics application, glass fiber reinforced PET is in the original PET resin pure plastic on the basis of adding glass fiber and other additives, so as to improve the scope of use of materials. Glass fiber reinforced PET can improve its impact resistance and thermal deformation temperature. PET plastic particles with ultra-high strength, rigidity, toughness, good dimensional stability and excellent heat resistance. The common glass fiber reinforcement ratio is PET GF30. After adding glass fiber filling, it can reach more than 160 degrees for a long time, which is suitable for most application scenarios.
Application: Automotive structural parts: luggage rack, door and window frame, motor housing and other electronic and electrical components: ignition components, relay seat, coil cover and other housing components.
