PBT materials Polybutylene terephthalate (PBT) is a thermoplastic polyester and one of the top five engineering plastics. PBT has excellent overall performance, is one of the toughest engineering plastics, and has high dimensional stability, good chemical resistance, excellent electrical insulation, good mechanical properties and elasticity, low water absorption, etc. PBT filling Long glass fiber compounds PBT (polybutylene terephthalate) is a polyester-based plastic, while glass fiber is a reinforcing material that is usually added to plastics in fiber form to enhance their mechanical properties. When PBT is combined with glass fibers, the following effects occur: 1. Enhanced strength and stiffness: glass fiber has excellent strength and stiffness, and adding it to PBT can significantly increase the mechanical properties of the plastic. This makes the material of PBT with glass fiber more strong and rigid when it is subjected to force or stress, and less likely to deform or break. 2. Improve heat resistance: glass fiber has a high melting point and good heat resistance performance. When glass fiber is added to PBT, it can improve the heat resistance of PBT, so that it can keep better performance at higher temperature and prevent softening or melting. 3. Improve corrosion resistance: Glass fiber has excellent corrosion resistance, and adding it to PBT can improve its resistance to chemicals, solvents and other corrosive media. This makes PBT with glass fiber have longer service life in some special environments. 4. Improve insulation performance: PBT itself has good insulation performance, and the addition of glass fiber further improves the insulation performance of PBT material. This makes the PBT with glass fiber more suitable for electrical and electronic applications, which can effectively isolate the current and reduce leakage and electromagnetic interference. All in all, PBT with glass fiber can enhance the mechanical properties, heat resistance, corrosion resistance and insulation properties of plastics, making them more widely used in various applications. However, the performance of the material may vary depending on the specific glass fiber content and the addition process. Fiber specification Grade Fiber specification Characteristics Application Length Color Package General grade 20%-60% High toughness, Low warpage Electronic appliances, mechanical parts, etc. About 12mm,  or customzied Natural color,  or customized 25kg/bag The difference between LGF & SGF Short glass fiber particles: Size size is about 3-4mm, length to width ratio 50-250 Long glass fiber particles: Size is about 10-12mm, aspect ratio >400 In addition, the distribution of glass fiber in the two kinds of particles is also different. Compared with SGF, the rigidity, strength and modulus of LGF have been improved, especially the notched impact performance has got a qualitative leap.
