<: B< br/> It is a milky white translucent to opaque crystalline thermoplastic polyester. It has high heat resistance, toughness and fatigue resistance, self-lubricating and low friction coefficient, weather resistance and low water absorption rate of only
<: %
, and it still maintains various physical properties (including electrical properties) in humid environments. , electrical insulation, but the volume resistance and dielectric loss are large. It is resistant to hot water, alkali, acid and oil, but is easily corroded by halogenated hydrocarbons, has poor hydrolysis resistance, can crystallize quickly at low temperatures, and has good formability. The disadvantages are low notched impact strength and large molding shrinkage. Therefore, most of them are modified with glass fiber reinforcement or inorganic filling. Their tensile strength and bending strength can be more than doubled, and the heat distortion temperature is also greatly increased. It can work under

℃
for a long time. The longitudinal and transverse shrinkage of the glass fiber reinforced product is inconsistent, which can easily cause the product to warp.

Mainly used in automotive electronics and electrical industry machinery and polymer alloy blending industry. For example, as distributors in automobiles, car body parts, igniter coil skeletons, insulating covers, exhaust system parts, motorcycle ignitions, and in the electronic and electrical industry, such as TV deflection coils, picture tubes and potentiometer brackets, audio output transformer skeletons, and adapters. 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, clock casings, mirror barrels, electric iron covers, mercury lamp shades, baking oven parts, power tool parts, shielding covers, etc.

The Chinese name is polybutylene terephthalate Glycol ester:
<: B
Born in the mid-1970s, Polymer then added new flame-retardant technology based on its advanced flame-retardant technology, and through combination Advanced compound technology has successfully developed flame-retardant

materials with excellent hot wire properties. There are no wall thickness restrictions on parts and shapes, and they can prevent hot wires from catching fire. test. Fires can occur due to direct fire or electrical fires. In recent years, fire-resistant safety requirements have been rising rapidly, focusing on electrical fires in electrical and electronic components.
