What is PBT?

Polybutylene terephthalate (PBT) is a thermoplastic polyester and one of the five engineering plastics.

PBT has excellent comprehensive performance, is one of the toughest engineering plastics, and has high dimensional stability, good chemical corrosion resistance, excellent electrical insulation, good mechanical properties and elasticity, low water absorption and so on.

What is PBT-LGF?

As one of the engineering plastics, most of the PBT needs to be modified to meet the corresponding requirements in the practical application field. PBT modification is mainly divided into: flame retardant PBT, glass fiber reinforced flame retardant PBT, glass fiber reinforced PBT.

The modified PBT material is mainly used in the field of lighting (such as LED lamp shell), electronic and electrical fields (such as relay shell and spinner, socket, optical fiber connector, etc.) and automotive manufacturing (such as junction box, ignition system parts, external door handles, etc.).

The difference between Long glass fiber & Short glass fiber

Long glass fibers range in length from 6 to 25mm, while staple fibers are usually less than 6mm, or even between 0.2 and 0.6mm.

Long glass fiber has more excellent performance in machanical properties. It is more suitable for large products and structural parts. It has 1-3 times higher (toughness) than short fiber, and the tensile strength (strength and rigidity) is increased by 0.5-1 times.

What is the application of PBT-LGF?

In the lighting industry, most of the lamp shell is used for enhanced flame retardant PBT material, whose performance requirements are easy to process and form, good mechanical properties, high and low temperature cycle resistance, flame retardant level UL94 3.0mm or 1.5mm V0, high temperature resistance, yellowing resistance effect is good. Its appearance requires transparent color or porcelain white shading, smooth surface, no floating fiber.

자동차 제조 분야에서 수정된 PBT는 주로 자동차 와이퍼 브래킷, 자동차 전조등 조명 링, 자동차 변속기 기어 박스, 앞 유리 기둥, 모터 쉘 등에 사용됩니다.
