Description
PBT material has excellent toughness and fatigue resistance, good heat resistance and weather resistance, good electrical performance, low water absorption, comprehensive comprehensive performance, and wide application. Glass fiber reinforced, glass fiber reinforced flame retardant modification can significantly improve its heat resistance, modulus, dimensional stability and flame retardancy. PBT modified plastics are widely used in automobiles, electronics and electrical industries.
Common Modification Methods
1. Reinforcement modification: adding glass fiber to PBT, the combination of glass fiber and PBT resin is good. After adding a certain amount of glass fiber to PBT resin, it can not only maintain the original advantages of PBT resin such as chemical resistance and processability, but also greatly improve its mechanical properties and overcome the notch sensitivity of PBT resin.
2. Flame retardant modification: PBT is a crystalline aromatic polymerase. If no flame retardant is added, its flame retardancy is UL94HB. Only after adding a flame retardant can it reach UL94V0.
3. Blending alloy modification: The main purpose of blending PBT with other polymers is to improve the notched impact strength, improve the warping deformation caused by shrinkage during molding processing, and improve heat resistance. The polymers used for blending modification of PBT mainly include PC, PET and so on. These products are mainly used in automobiles, electronics, and electric tools. The proportion of glass fiber is different, and the application fields are also different.
