917992-1 26 pin connector with material PBT
Product Presentation
PBT, full name as Polybutylene terephthalate, is a milky white translucent to opaque, semi-crystalline thermoplastic polyester. It is an important thermoplastic polyester and one of the five major engineering plastics. Its basic information is as follows:
Full Name: Polybutylene Terephthalate
Abbreviation: PBT
Special properties: High Heat Resistance, Toughness, Fatigue Resistance
Appearance: milky white translucent to opaque, semi-crystalline solid
Chemical formula: (C12H12O4) n
Melting point: 233℃
Most PBT resins are processed into compounding materials. After modification with various additives, they can be blended with other resins to obtain good comprehensive properties such as heat resistance, flame retardant, electrical insulation, and good processing properties. Widely used in electrical appliances, automobiles, aircraft manufacturing, communications, home appliances, transportation, and other industries. Typhoenix will briefly talk about the advantages and disadvantages of PBT plastic material functions.
Advantages
✔ Excellent mechanical properties, especially high rigidity and hardness.
✔ Good heat resistance, the heat distortion temperature can reach more than 180 °C, and the heat resistance is 150 °C. After adding glass fiber, the heat resistance can be increased to 200 °C, which can be used to manufacture electronic components that require high dimensional stability under high temperature conditions for a long time.
✔ Good surface gloss function, especially suitable for spray-free electronic and electrical products.
✔ Fast crystallization speed, good fluidity and excellent formability, suitable for injection processing of electrical parts with complex structures.
✔ Good thermal stability, especially with low thermal expansion and dimensional shrinkage.
✔ Good resistance to chemicals, solvents and weathering.
✔ High breakdown voltage, suitable for making high-voltage parts.
✔ Low hygroscopicity and minimal impact on electrical and dimensional stability. The water absorption rate is low, only 0.1%, and it still maintains various physical properties (including electrical properties) and electrical insulation in a humid environment.

Defects
● Molecules contain ester bonds and will decompose under the action of strong acids, strong bases and water vapor
● The material is more sensitive to notches and is brittle
In view of its superior performance, PBT has become one of the main raw materials for making plug connectors. At the same time, it is necessary to store PBT in a dry, ventilated, rainproof and sun-proof place, away from high temperature and open fire, and avoid mixed loading and transportation with strong acid, strong alkali and strong oxidant.
The Typhoenix connector is made of high-quality raw materials. All incoming materials undergo strict quality inspection before they can be put into storage and entered into the production process. If you encounter any connector problems, we are ready to service you.
