Concept Introduction
Polyethylene terephthalate, chemical formula:COC6H4COOCH2CH2O。(Please provide the Chinese content that needs to be translated into American English.:Polyethylene terephthalateN/APET)Dimethyl terephthalate and ethylene glycol are first synthesized into dimethyl terephthalate dihydroxyethylate through ester exchange or esterification with terephthalic acid and ethylene glycol, followed by a condensation reaction to obtain the final product.Plastic PowderCrystalline saturated polyester, a milky white or pale yellow, highly crystalline polymer with a smooth and glossy surface. It is a common resin in everyday life and can be divided intoAPET、RPETAndPETG。
Excellent physical and mechanical properties over a wide temperature range; long-term service temperature up to120℃Excellent electrical insulation properties, even under high temperature and high frequency, its electrical performance remains good; however, it has poor corona resistance, good creep resistance, fatigue resistance, friction resistance, and dimensional stability.
Primary Application
Primarily applied in the electronics and electrical field: electrical outlets, electronic connectors, rice cooker handles, TV yokes, terminal blocks, circuit breaker enclosures, switches, motor fan enclosures, instrument mechanical parts, money-counting machine parts, irons, accessories for induction cooktops and ovens; in the automotive industry: flow control valves, carburetor caps, window controllers, foot-operated shifters, distribution panel covers; in the machinery industry: gears, blades, pulley wheels, pump parts; also, wheelchair frames and wheels, lampshade enclosures, lighting fixture enclosures, drain pipe connectors, zippers, watch parts, sprayer components.
Cautionary Notes
PET It is a milky white or light yellow, highly crystalline polymer with a smooth and glossy surface. It exhibits excellent physical and mechanical properties over a wide temperature range, with a long-term use temperature of120℃Excellent electrical insulation properties, even under high temperature and high frequency conditions, maintaining good electrical performance; however, poor corona resistance, good creep resistance, fatigue resistance, wear resistance, and dimensional stability.PETPlastic PowderContains ester bonds, which can decompose under the action of strong acids, strong bases, and steam. Resistant to organic solvents and weathering. Drawbacks include slow crystallization rate, difficult molding and processing, high molding temperatures, long production cycles, and poor impact resistance. Generally, processing and physical properties are improved by methods such as reinforcement, filling, and blending, with glass fiber reinforcement showing significant effects, enhancing the resin's rigidity, heat resistance, chemical resistance, electrical properties, and weather resistance. However, the drawback of slow crystallization speed still needs to be addressed, which can be achieved by adding nucleating agents and crystallization accelerators. Adding flame retardants and flame-retardant droplet inhibitors can improve PETFlame retardancy and self-extinguishing properties.
