What is PBT resin plastic granules?
Injection grade PBT (Polybutylene Terephthalate) is a high performance engineering plastic, full name polybutylene terephthalate. It has excellent comprehensive properties, including high mechanical properties, thermal stability, electrical insulation, chemical corrosion resistance, etc. Because of its unique properties, this material has been widely used in the fields of automobiles, home appliances, communication electricians and power tools
Why PBT raw material can be used for making automotive parts?
PBT (polybutylene terephthalate) raw materials as one of the five major general engineering plastics, in the manufacture of automotive parts has many significant advantages :
Good mechanical properties: excellent toughness and fatigue resistance, able to withstand all kinds of vibration, impact and pressure generated by the car in the process of driving, to ensure that the auto parts are not easy to be damaged in the long-term use of the process, to extend its service life. Reinforcement modification can significantly improve its modulus, to meet the strength requirements of different parts of the car.
High dimensional stability: PBT raw material has low water absorption, and its dimensional changes are small under different humidity environments. This enables automotive parts made from PBT raw materials to maintain precise dimensions at all times, ensuring a perfect fit with other components and reducing assembly problems and failures caused by dimensional deviations.
Heat resistance, weather resistance: can maintain stable performance in a wide range of temperatures, able to withstand high temperatures generated by the engine compartment and other parts of the car, but also adapt to the climatic conditions of different regions and seasons, and is not easy to deformation, aging and other problems due to temperature changes.
Advantage of chemical properties Strong chemical resistance: in the use of the car, accessories may come into contact with a variety of chemicals, such as gasoline, oil, coolant, detergent, etc. PBT raw materials have excellent chemical resistance, to resist the erosion of these chemicals, to ensure that the performance and appearance of the accessories will not be affected.
Excellent electrical properties: for electronic and electrical parts in automobiles, such as connectors, switches, etc., good electrical insulation properties are crucial.PBT materials have excellent electrical properties, which can effectively prevent current leakage and short circuit problems, ensuring the safe and stable operation of automotive electronic systems.
Processing Performance Advantages Good moulding processability: PBT material has a fast crystallization speed, which makes it suitable for a variety of processing methods, such as injection moulding, extrusion and blow moulding. In injection moulding processing, it can fill moulds quickly to achieve complex shapes, and has a short moulding cycle and high production efficiency. In addition, its better fluidity can ensure the surface quality and dimensional accuracy of the product.
