PBT engineering plastics are widely used in electronics, car industry, office machinery and other fields. In Japan and the developed countries in Europe, PBT engineering plastics are mainly used in the fields of electronic appliances and car industry. In terms of Asia, except Japan, the car industry is still underdeveloped. PBT is relatively less used and consumed in cars and more in electronics and electrical appliances. The application scope of PBT engineering plastics in China mainly includes the following aspects:

(1) car industry.

PBT engineering plastics are mainly used in the production of three types of parts: first, all kinds of parts outside the car, including the corner grille and the corresponding exothermic hole cover of the engine, which show outstanding stability, chemical resistance, long-term wear resistance, anti-aging resistance and high strength; 2、 Various parts and components inside the car, including control system valve, endoscope brace and wiper bracket, show low warpage, high strength and anti-aging; 3、 Car electrical parts, including various types of electrical connectors and ignition coil twisted tubes, show stability, dielectric and flame retardancy.

(2) mechanical equipment.

In this category, PBT engineering plastics are mainly used to produce baking machine parts, electric iron covers, computer covers, mercury lamp covers, cams, camera parts, gears, electronic watch shells and various buttons, etc. their use characteristics are flame retardance and heat resistance.

(3) energy saving lamp. In this category, PBT engineering plastics are mainly used to produce energy-saving lamp caps, which show the use characteristics of aging resistance, heat resistance and flame retardant grade up to UL94V-0.

(4) heat dissipation fan. In this category, PBT engineering plastics are mainly used to produce computer CPUs, power supplies and corresponding heat dissipation fans for motors. Its application characteristics are high temperature resistance, fatigue resistance, high strength, creep resistance, outstanding dimensional stability and flame retardancy.

(5) connector. In this category, PBT engineering plastics are mainly used for the corresponding connectors of computers, various household appliances, communications and digital products, such as the corresponding sockets of telephone lines and network cables, the corresponding slots of computer motherboards, etc. their use characteristics are heat resistance, fatigue resistance, electrical insulation, high strength and flame retardancy.

(6) coil framework. PBT engineering plastics are mainly used to produce coil framework, and its application characteristics are dielectric strength, heat resistance, resistance, strength and flame retardancy.

(7) relay. In this category, PBT engineering plastics are mainly used to produce relay bottom covers, spools and housings. Their use characteristics are long-term heat aging resistance, temperature resistance, flame retardancy, forming and processing functions and electrical functions.

(8) optical fiber cable. In this category, PBT engineering plastics are mainly used to produce optical fiber bundle tubes, which show excellent dimensional stability, mechanical function, heat resistance, low linear expansion coefficient and high molding yield.

The electronic and electrical industry has a huge consumption of PBT resin. Modified PBT engineering plastics have the characteristics of dielectric, heat resistance, flame retardancy and high strength. They are mostly used to produce high-voltage packs, brush supports and corresponding frames of output transformers, electrical switches and igniters.
