聚碳酸酯 PC
PC特性: 耐热、天然防火、V2级,透明、尺寸稳定、抗冲击性好、聚碳酸酯耐弱酸,耐中性油
缺点:不易加工,易脆,不耐磨,不抗刮花 不耐紫外光,不耐候,不耐强碱,
PC 中文名 聚碳酸酯 俗称:防弹胶 五大工程塑胶中唯一的透明产品
PC 相对密度1.19~1.2% 透光89% 热变型温度135度左右,长期使用温度-60~120度
PC高温下水解
不耐磨一些用于易磨损用途的PC器件需要对其表面进行特殊处理
针对PC不抗刮花 美国GE生产出一款抗刮花DMX开头的PC
美国GE生产一款耐低温 以EXL开头PC
针对PC的缺点对其改性增强 PC密度在1.2%以上
》玻璃纤维增强GF,提高强度,耐热温度
》铁氟龙PTFE增强L,耐磨,耐化学性好
》与其它材料合金
》PC加工困难,易粘模,加脱模剂,使它不粘模 R,
》阻燃增强V 阻燃等级
》PC不耐候,不耐紫外,对其添加UV剂,抗紫外
》碳纤维增强 导电,电磁屏蔽(EMI)
绝缘性能:优良(潮湿、高温也能保持电性能稳定,是制造电子、电气零件的理想材料);
机械性能:强度高、耐疲劳性、尺寸稳定、蠕变也小(高温条件下也极少有变化);
PC塑胶原料性能优越,有阻燃级、抗UV级、食品级、玻纤增强级、高韧性、光学级、耐化学性、耐寒性、医用级、
可接触日常餐具、化学器皿、婴幼儿奶瓶、超薄制品、电器外壳、导电产品、电源支架、寿命性佳。
生产品牌有:三菱工程PC、出光PC、拜耳PC、奇美PC、陶氏PC、三星PC、住友化学PC、帝人PC等。
