产品细节
775度Gwit PBT+30%玻璃纤维树脂
PBT分子中的苯环和酯基形成一个大的共轭体系，这降低了分子链的柔韧性，增加了分子刚性，极性酯基和铌基的存在增加了分子间作用力，分子刚性进一步增强，韧性很差。解决方案：a）聚合改性聚合改性是在聚合过程中，通过共聚合、接枝、镶嵌、交联等方式，在PBT分子中引入新的柔性链段，使其具有良好的韧性。b） 混合和改性改性是将改性剂或高抗冲强度材料与PBT混合或复合，使其作为分散相分布在PBT基体中，利用两种组分的部分相容性或适当的界面粘结效应，提高PBT的间隙冲击性能。如在PBT中加入反应性电容剂POE-g-GMA，通过GMA和PBT端基原位增容反应，增强界面力，以达到增韧效果

Product Details
775 Degree Gwit PBT+30% Glassfiber Resin
The benzene ring and ester base in the PBT molecule form a large conjugate system, which reduces the flexibility of the molecular chain, increases the molecular rigidity, and the presence of polar ester base and niobium base increases the intermolecular force, and the molecular rigidity is further enhanced, thus making the toughness very poor. Solution: a) Aggregation modification Polymerization modification is the introduction of new flexible chain segments in PBT molecules in the polymerization process by means of co-convergence, grafting, inlaying, crosslinking, etc., so that it has good toughness. b) Commixing and modification Comic modification is the mixing or compounding of modifier or high impact strength material with PBT, so that it is distributed as a dispersion phase in the PBT substrate, using the partial compatibility of the two components or the appropriate interface bonding effect, improve the PBT’s gap impact performance. Such as the addition of reactive capacitant POE-g-GMA in PBT, through the GMA and PBT end-based in situ capacity-enhancing reaction, strengthen the interface force, in order to achieve toughening effect
