Polybutylene terephthalate, the English name is polybutylene terephthalate (PBT for short), PBT is a milky white translucent to opaque, crystalline thermoplastic polyester. It has high heat resistance, toughness, fatigue resistance, self-lubrication, low friction coefficient, weather resistance, and low water absorption rate of only 0.1%. It still maintains various physical properties (including electrical properties) and electrical insulation in humid environments. However, the volume resistance and dielectric loss are large. Resistant to hot water, alkalis, acids, and oils, but susceptible to corrosion by halogenated hydrocarbons, poor hydrolysis resistance, rapid crystallization at low temperatures, and good formability.

Process conditions
Drying treatment: This material is easily hydrolyzed at high temperatures, so drying before processing is very important. The recommended drying conditions in the air are 120°C for 6 to 8 hours, or 150°C for 2 to 4 hours. Humidity must be less than 0.03%. If drying with a hygroscopic dryer, the recommended conditions are 150°C, 2.5 hours.
Melting temperature: 225~275ºC, recommended temperature: 250ºC.
Mold temperature: 40~60ºC for unreinforced materials. The cooling cavity of the mold must be well designed to reduce the bending of the plastic part. The heat must be dissipated quickly and evenly. It is recommended that the diameter of the mold cooling cavity is 12mm.
Injection pressure: medium (up to 1500bar).
Injection speed: The fastest possible injection speed should be used (because PBT solidifies quickly).
Runner and gate: It is recommended to use circular runner to increase pressure transmission (empirical formula: runner diameter = plastic part thickness + 1.5mm). Various types of gates can be used. Hot runners can also be used, but care should be taken to prevent leakage and degradation of materials. The gate diameter should be between 0.8~1.0*t, where t is the thickness of the plastic part. If it is a submersible gate, the recommended minimum diameter is 0.75mm.

Application

 

PBT (reinforced and modified PBT) is mainly used in automobiles, electronic appliances, industrial machinery and polymer alloys and blending industries. Such as distributors, car body parts, ignition coil bobbins, insulating covers, exhaust system parts, motorcycle igniters, and electronic and electrical industries such as TV deflection coils, picture tubes and potentiometer brackets, audio output Transformer skeleton, adapter skeleton, switch connector, electric fan, refrigerator, washing machine motor end cover, bushing. In addition, there are transportation machinery parts, sewing machine and textile machinery parts, watch casings, mirror barrels, electric iron covers,  baking oven parts, power tool parts, shielding sleeves, etc.
