电气连接器用玻璃纤维增强PBT颗粒PBT GF30 Fr V0
电气连接器用玻璃纤维增强PBT颗粒PBT GF30 Fr V0选择低分子量PBT，但分子量的降低会影响机械性能。硬脂酸盐或褐煤等流动促进剂可以改善PBT的流动性，但这些低分子量酯会在产品加工和使用过程中渗出。对于需要增韧的PBT材料，增韧剂的加入必然会导致流动性降低，因此有必要选择对流动性影响较小的增韧剂。添加具有特定结构的均相低分子量聚酯，例如CBT，CBT是一种具有大环寡酯结构的功能性树脂，与PBT具有良好的相容性，并且极少量的添加可以在不影响机械性能的情况下大大提高树脂的流动性。随着纳米材料的加入，纳米材料的理想分散在PBT中起着类似于内部润滑的作用，可以提高PBT的流动性，但纳米填料的分散是共混改性过程中的一个主要难点

Product Details
Glass Fiber Reinforced PBT Granules PBT GF30 Fr V0 for Electrical Connector
Choose low molecular weight PBT, but the decrease in molecular mass can affect mechanical properties. Flow promoters such as stearates or lignites can improve PBT flowability, but these low molecular mass esters can seep out during product processing and use. For PBT materials that need to be toughened, the addition of tougheners will definitely lead to a decrease in fluidity, so it is necessary to choose a toughener that has less impact on fluidity. Adding homogeneous low-molecular-weight polyesters with specific structures, such as CBT, CBT is a functional resin with a large ring oligoester structure, which has good compatibility with PBT, and a very small amount of addition can greatly improve the fluidity of the resin without affecting the mechanical properties. With the addition of nanomaterials, the ideal dispersion of nanomaterials plays a role similar to internal lubrication in PBT, which can improve the fluidity of PBT, but the dispersion of nanofills is a major difficulty in the process of blending modification.
