产品详细信息

PC工程塑料的特点

PC无色、透明、耐热、耐冲击、阻燃双级，在正常使用温度下具有良好的机械性能。PC具有良好的抗冲击性、高折射率和良好的加工性能。PC的主要性能缺陷是耐水解性不够高，对缺口敏感，耐有机化学性、耐划伤性差，长时间暴露在紫外线下会变黄

PC工程塑料的加工条件

PC工程塑料具有优异的综合性能，特别适用于制造尺寸精确、形状复杂、载荷轻或冲击载荷小的小型零件。在加工过程中，粘度随着温度的升高而降低，必须严格控制原料干燥、注射温度和模具温度三个条件

PC工程塑料的注射压力注塑压力对零件性能的影响主要体现在保压时间上。保压时间短，零件收缩，或出现缩孔和真空气泡；延长保压时间，特别是对于大面积厚壁零件，可以增加其密度，消除真空孔，提高尺寸稳定性；保压时间过长，会对工件产生内应力，容易开裂

PC Polymer Granules

Product Details

Features of PC engineering plastics

PC is colorless, transparent, heat-resistant, impact-resistant, flame-retardant BI grade, and has good mechanical properties at ordinary use temperatures. PC has good impact resistance, high refractive index and good processing performance. The main performance defects of PC are that the hydrolysis resistance is not high enough, it is sensitive to notch, organic chemical resistance, scratch resistance is poor, and it will turn yellow when exposed to ultraviolet light for a long time.

Processing conditions of PC engineering plastics

PC engineering plastics have excellent comprehensive properties, and are especially suitable for the manufacture of small parts with precise dimensions, complex shapes, and light loads or less impact loads. During the processing, the viscosity decreases with the increase of temperature, and it is necessary to strictly control the three conditions of raw material drying, injection temperature and mold temperature.

Injection pressure of PC engineering plastics

The influence of injection pressure on the performance of parts is mainly reflected in the holding time. The pressure holding time is short, the parts shrink, or shrinkage voids and vacuum bubbles appear; prolonging the pressure holding time, especially for large-area thick-walled parts, can increase its density, eliminate vacuum holes, and improve dimensional stability; pressure holding time is too long , which will cause internal stress to the workpiece and be prone to cracking.
