物理改性PBT树脂
物理改性：在PBT中加入20%~40%的玻璃纤维后，玻璃纤维增强改性不仅保持了PBT原有的耐化学性和加工性等优点，而且大大提高了力学性能，如抗拉强度、弯曲强度提高了1~115倍，弹性模量提高了2倍，克服了PBT缺口冲击强度低的缺陷。性爱很好。PBT改性虽然可以提高玻璃纤维的各向异性和增强性，但可以改善玻璃纤维的综合翘曲性能。为了解决这一问题，可以采用矿物填料、矿物和玻璃纤维复合填料等聚合物进行共混改性，达到翘曲的目的

Product Details
Physical Modified PBT Resin
Although PBT has comprehensive properties, when used alone, it also has low thermal deformation temperature, easy combustion, shrinkage and warpage of parts, and poor mechanical properties, especially the notched impact strength of products.
and other shortcomings, so PBT is rarely used alone, and most of them must be modified before they can be applied. The modification of PBT mainly starts from two aspects: one is to use chemical modification, that is, to make it have better performance and new functions through chemical methods such as copolymerization, grafting, block, cross-linking or degradation; The physical modification method is to improve and improve the comprehensive performance of PBT by filling and reinforcing inorganic materials, blending with other resins and adding various additives. Physical modification is extremely effective for developing varieties with different properties.
Physical modification: glass fiber reinforced modification not only maintains the original advantages of PBT such as chemical resistance and processability after adding 20%~40% glass fiber to PBT, but also greatly improves mechanical properties, such as tensile strength The bending strength is increased by 1~115 times, the elastic modulus is increased by 2 times, and the deficiency of low notched impact strength of PBT is overcome. good sex. Although low warpage modified glass fiber reinforcement can improve and improve the comprehensive properties of PBT resin, but due to the anisotropy of glass fiber orientation, it will cause product warpage deformation. To solve this problem, mineral filling, mineral and glass fiber composite filling and other polymers can be used for blending modification to achieve the purpose of warping.
