Product Introduce
PBT PBT is a versatile thermoplastic that is often enhanced by blending with other plastics or incorporating various additives. This adaptability allows for the creation of products with tailored specifications. Renowned for its impressive heat resistance, excellent weather and chemical durability, superior electrical properties, minimal water absorption, and attractive gloss, PBT finds extensive applications across diverse industries such as electronics, automotive, machinery, and home products.
Notable Features of PBT:
1. PBT boasts outstanding electrical insulation capabilities and maintains low water absorption, ensuring reliability in humid conditions.
2. It exhibits robust resistance to a variety of chemicals, solvents, and pharmaceutical substances, making it ideal for demanding environments.
3. When reinforced with glass fiber, PBT achieves a high thermal deformation temperature, enhancing its structural integrity under heat.
4. PBT's rapid crystallization, excellent fluidity, and superior molding performance make it a preferred choice for intricate designs.
5. This material is highly versatile, allowing for blending and modification with different plastics to meet specific needs.
6. PBT is characterized by its low friction coefficient, exceptional wear resistance, and minimal bending creep, contributing to its longevity.
Polybutylene Terephthalate (PBT) is a synthetic thermoplastic polyester within the esteemed polyester series.It is synthesized through the polycondensation of with either terephthalic acid (PTA) or dimethyl terephthalate (DMT), resulting in a material with a unique set of properties.The chemical composition of PBT features a relative molecular weight ranging from 30,000 to 40,000, contributing to its robust nature.Typically, PBT presents as a milky-white to semi-transparent, opaque crystalline material with an appealing glossy surface and a density of 1.31 to 1.55 g/cm³..
PBT is highly regarded for its exceptional mechanical strength, fatigue resistance, and dimensional stability, proving indispensable for precision components. It maintains low water absorption of 0.1%, offers excellent electrical insulation in humid conditions, and withstands exposure to oils, alkalis, and most solvents, though it is vulnerable to halogenated hydrocarbons. PBT's rapid crystallization at low temperatures facilitates efficient injection molding, extrusion, or blow molding processes. Its versatility extends to the electronics sector (connectors, circuit boards), automotive (engine parts, sensors), and mechanical industries (gears, bearings). Additionally, its capabilities are enhanced through modifications with glass fibers or flame retardants for specialized, high-performance applications.

Application
Our remarkable PBT resin has been meticulously modified with a range of cutting-edge additives and smartly blended with other resins to achieve exceptional comprehensive properties. This combination imparts outstanding heat resistance, superior flame retardancy, and excellent electrical insulation, coupled with the added benefit of outstanding processing capabilities.
PBT-modified materials have won the acclaim of numerous industries, finding extensive applications in electrical appliances, automobiles, aircraft manufacturing, communications, home appliances, and transportation. For instance, when enhanced with glass fiber, PBT becomes ideal for crafting electronic components that demand high dimensional stability, even in prolonged high-temperature conditions.
Boasting a high breakdown voltage, PBT is the go-to choice for fabricating high voltage-resistant components. Its superior fluidity when molten makes it perfect for injection molding, particularly for intricate electrical parts such as integrated circuit sockets, printed circuit boards, computer keyboards, as well as electrical switches, fuses, temperature control switches, and protectors. Additionally, in the automotive sector, it is utilized in the manufacturing of car bumpers, carburetors, spark plugs, fuel supply systems, and igniters. In the communications domain, PBT's versatility is showcased in the production of integrated modules for program-controlled telephones, wiring boards, and power tools.
