高热稳定性PBT 30%玻璃纤维树脂
玻璃纤维增强PBT材料容易翘曲原因：翘曲是材料不均匀收缩的结果。材料中组件的取向和结晶、注塑时使用不合适的工艺条件、模具设计中浇口的形状和位置不正确、产品设计不均匀时的壁厚等都会导致产品翘曲。PBT/GF复合材料的翘曲主要是玻璃纤维在流动方向上的取向限制了树脂收缩，而玻璃纤维周围PBT的诱导结晶增强了这种效应，因此产品的垂直（流动方向）小于水平（流动方向的垂直方向），这导致PBT/GF复合材料发生翘曲。解决方法：首先，加入矿物，利用矿物填料形状的对称性，减少玻璃纤维取向造成的各向异性；二是加入无定形材料，减少PBT的结晶，减少asA或as等结晶引起的不均匀收缩，但它们与PBT的相容性较差，需要添加合适的相容剂；第三，调整注塑工艺，如适当提高模具温度，适当增加注塑周期

Product Details
High Thermal Stability PBT 30% Glassfiber Resin
Glass fiber-reinforced PBT material easy warping Cause: Warping is the result of uneven shrinkage of the material. The orientation and crystallization of the components in the material, the use of inappropriate process conditions when injection molding, the shape and position of the gate is not correct in the mold design, the thickness of the wall when the product design is uneven, etc. will cause the warping of the product. The warping of PBT/GF composite material is mainly the orientation of the glass fiber in the direction of flow limits the resin shrinkage, and the induced crystallization of PBT around the glass fiber strengthens this effect, so that the vertical (flow direction) of the product is less than the horizontal (perpendicular direction of the flow direction), which leads to the warping of the PBT/GF composite material. Solution: First, the addition of minerals, the use of mineral filler shape symmetry to reduce the glass fiber orientation caused by anisotropy; Second, the addition of amorphous materials, reduce the crystallization of PBT, reduce the uneven shrinkage caused by crystallization, such as as asA or AS, but they are poor compatibility with PBT, the need to add appropriate compatibility agents; Third, adjust the injection molding process, such as appropriately increase the mold temperature, appropriately increase the injection molding cycle.
