PET engineering plastics have excellent comprehensive properties, such as high rigidity, low creep, high mechanical strength, good
heat resistance, and good electrical insulation. They can be used in harsh chemical and physical environments for a long time and can
replace metals as engineering structural materials. use. As one of the five major engineering plastics, PET has strong plasticity and
excellent performance, and is widely used.
1.What is PET engineering plastic?
PET is the abbreviation of Polyethylene terephthalate, its scientific name is polyethylene terephthalate, and its chemical formula is
[COC6H4COOCH2CH2O]n. PET engineering plastics have excellent physical and mechanical properties in a wide temperature range.
The long term use temperature can reach 120°C. They have excellent electrical insulation. Even at high temperatures and high frequencies,
their electrical properties are still good, and they are creep resistant and Fatigue resistance, friction resistance and dimensional stability
are all very good. Resistant to oil, fat, acid, dilute alkali, and most solvents. It has excellent high and low temperature resistance and can
be used for a long time in the temperature range of 120°C. It can withstand high temperatures of 150°C and low temperatures of -70°C
for short-term use, and has little impact on its mechanical properties at high and low temperatures.
2. Modified PET engineering plastics
Reinforcement, flame retardant modification and alloying modification of PET plastic can significantly improve its heat resistance, modulus,
toughness, dimensional stability and flame retardancy. There are enhanced toughening grade, enhanced low warpage grade,
enhanced Flame retardant, low warpage enhanced flame retardant, color stable enhanced flame retardant, high gloss enhanced flame
retardant, halogen free flame retardant and other series. Modified PET plastics are widely used in the fields of electronics, automobiles, and home appliances.
Compared with other modified plastics, modified PET engineering plastics have the advantages of heat resistance, good mechanical
properties, and high cost performance.
3. Applications of PET engineering plastics in various fields
In the field of electronics and electrical, the halogen free flame retardant reinforced PET material with high glow wire and high CTI has excellent
resistance to yellowing and precipitation, and good molding processability. It is mainly used in inverter frames, frames, compressor
terminal covers, Relays etc.
In the field of home appliances, modified PET engineering plastics are mainly used in lamp holders, soy milk machine bases, hair straighteners,
IH square cooker coil plates, electric iron casings, air fryers, etc. Polyceron reinforced PET plastic has excellent mechanical properties, good
dimensional stability, high heat resistance, good surface gloss, and good color stability. It is used in oven handles, home appliance casings,
rice cooker electromagnetic heating plates, etc.
In the automotive field, modified PET engineering plastics generally improve overall performance through enhanced modification or alloying.
Enhanced PET plastics and PET alloy materials have excellent mechanical properties, good dimensional stability, high heat resistance, good
surface gloss, and good color stability. , applications in the automotive field mainly include door handles, fog light brackets, reflectors, heat
vents, heating coils, air conditioning outlets, etc.
