PBT materials

Polybutylene terephathalate (PBT) is a crystalline thermoplastic engineering plastic made by polymerizing dimethyl terephthalate (DMT) and 1,4 butanediol (1,4-Butanediol). Due to the growth of the -CH2- chain of PBT resin, the molecular chain is easy to flex, so the glass transfer temperature is lower than that of PET, and the crystallization speed increases.

PBT can also be called thermoplastic polyester plastics, applicable to different processing industries, generally more or less will add additives, or blended with other plastics, with different proportions of additives, can be manufactured with different specifications of the product. Because PBT has heat resistance, weather resistance, chemical resistance, good electrical properties, low water absorption, good gloss, widely used in electronic and electrical appliances, automotive parts, machinery, household goods, etc..

PBT's downstream applications include the automotive, electronics/electrical appliance, and machinery industries.

Advantages of Long glass fiber reinforced materials

Glass fiber reinforced plastic is based on the original pure plastic, adding glass fibers and other additives, so as to improve the scope of use of the material. Generally speaking, most of the glass fiber reinforced materials are used in the structural parts of the products, which is a kind of structural engineering materials, such as: PP, ABS, PA66, PA6, PC, POM, PPO, PET, PBT, PPS and so on.

Advantages

After glass fiber reinforcement, glass fiber is a high temperature resistant material, therefore, the heat-resistant temperature of reinforced plastics is much higher than before without glass fiber, especially nylon plastics.

After glass fiber reinforcement, due to the addition of glass fiber, it restricts the mutual movement of the polymer chain of the plastic, therefore, the shrinkage of the reinforced plastic decreases a lot and the rigidity is greatly improved.

After glass fiber reinforced, the reinforced plastic will not stress cracking, at the same time, the impact resistance of the plastic improves a lot.

After the glass fiber reinforcement, the glass fiber is a high strength material, which also greatly improves the strength of the plastic, such as: tensile strength, compression strength, bending strength, improve a lot.

After glass fiber reinforcement, due to the addition of glass fiber and other additives, the combustion performance of the reinforced plastics decreases a lot, most of the materials can not be ignited, it is a kind of flame-retardant material.
