产品详细信息

注射用白色塑料PP FR V0颗粒

1。当温度低于50度时，塑件不光滑，易产生熔合不良，留下痕迹，超过90度容易发生翘曲变形

2。流动性好，但收缩范围和收缩值大，容易出现缩孔。凹痕，变形

3。塑料壁厚应均匀，避免缺胶、尖角，以防止应力集中

4。结晶，吸湿性小，易发生熔体破裂，长期接触热金属易分解

5。冷却速度快，浇注系统和冷却系统散热慢，注意控制成型温度。材料的低温方向是明显的。在低温和高压下尤其如此

PP material molding performance

1.When the temperature is lower than 50 degrees, the plastic parts are not smooth, easy to produce bad fusion, leaving marks, more than 90 degrees prone to warping deformation

2.Good mobility, but the shrinkage range and shrinkage value is large, prone to shrink holes. Dents, deformation.

3.Plastic wall thickness should be uniform, to avoid lack of glue, sharp angle, in order to prevent stress concentration.

4.Crystallization, small moisture absorption, easy to occur melt rupture, long-term contact with hot metals easy to decompose.

5.The cooling speed is fast, the pouring system and the cooling system should be slow to dissipate heat, and pay attention to control the molding temperature. The direction of the low temperature of the material is obvious. This is especially true at low temperatures and high pressures.
