High Quality Raw Material Plastic Material PBT Engineering Plastic Granules PBT CAS26062-94-2

PBT plastic raw material (Polybutylene Terephthalate), also known as polybutylene terephthalate, is a milky white translucent to opaque crystalline thermoplastic polyester. PBT materials have high strength and rigidity, especially glass additive type PBT, whose tensile strength can be as high as 170MPa.

This allows PBT to maintain a stable shape when subjected to large external forces and is not easy to deform. Therefore, it is suitable for manufacturing parts with high structural strength requirements, such as automobile bumpers and industrial machinery brackets.

After repeated stress, PBT materials can still maintain good performance and are not prone to fatigue damage. This feature can extend the service life of the product, making it often used in the manufacture of parts that need to withstand dynamic loads for a long time, such as gears and springs.

PBT has low water absorption and a small thermal expansion coefficient, so its dimensional changes are very small under different temperature and humidity environments. This excellent dimensional stability can ensure the accuracy and reliability of the product during use, and is particularly suitable for manufacturing parts for precision instruments and electronic equipment, such as connectors and switches.

Under high temperature conditions, PBT materials have very little creep phenomenon, that is, the material has a small degree of deformation under long-term stress and can maintain good mechanical properties. This property makes PBT suitable for some parts that work in high temperature environments and have strict dimensional accuracy requirements.
