抗紫外线PC 2807 2807德国拜耳/PC原材料
抗紫外线PC 2807 2807德国拜耳/PC原材料
主要性能
1.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);
2.耐热老化性:增强后的UL温度指数达120~140℃(户外长期老化性也很好);
3.耐溶剂性:无应力开裂;
4.对水稳定性:高温下遇水易分解(高温高湿环境下使用需谨慎);
5.电气性能:
6.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);
7.介电系数:3.0—3.2;
8.耐电弧性:120s;
9.成型加工性:普通设备注塑或挤塑。

产品概述
聚碳酸酯(英文简称PC)是分子链中含有碳酸酯基的高分子聚合物,根据酯基的结构可分为脂肪族、芳香族、脂肪族-芳香族等多种类型。其中由于脂肪族和脂肪族-芳香族聚碳酸酯的机械性能较低,从而限制了其在工程塑料方面的应用。
仅有芳香族聚碳酸酯获得了工业化生产。由于聚碳酸酯结构上的特殊性,已成为五大工程塑料中增长速度 快的通用工程塑料。

Huayun Plastics PC is a linear carbonated polyester in which the carbonated groups alternate with other groups, which may be aromatic, aliphatic or both. Bisphenol a type PC is the most important industrial product. PC is an amorphous polymer of almost colorless glassy state with good optical properties. Pc High Molecular Weight Resin has high toughness, the notched impact strength of cantilever beam is 600 ~ 900J / m, the thermal deformation temperature of unfilled grade is about 130 °c, the value can be increased by 10 °c after glass fiber reinforced. The bending modulus of PC can reach over 2400MPA, and the resin can be processed into large rigid products. Under 100 °C, the creep rate under load is very low. PC poor hydrolysis resistance, can not be used for repeated exposure to high-pressure steam products. The main defects of PC are poor hydrolytic stability, sensitivity to notch, resistance to organic chemicals, poor scratch resistance and yellowing after long-term exposure to ultraviolet light. Like other resins, PC is susceptible to erosion by certain organic solvents.
