PC/ABS(沙伯基础C6600)耐热级
In addition, in order to meet the requirements of thin-walled instrument panel, the series of materials can reduce the viscosity of the materials under high shear, and overcome the disadvantages of thermal decomposition of the materials caused by one-sided raising of temperature to improve the fluidity of the materials in the past.
PC/ABS,聚碳酸酯和丙烯腈-丁二烯-苯乙烯共聚物和混合物,是由聚碳酸酯(Polycarbonate)和丙烯腈-丁二烯-苯乙烯共聚物(ABS)合并而成的热可塑性塑胶,结合了两种材料的优异特性,ABS材料的成型性和PC的机械性、冲击强度和耐温、抗紫外线(UV)等性质,颜色是无透明颗粒,可广泛使用在汽车内部零件、商务机器、通信器材、家电用品及照明设备上.
PC/ABS是一种通过混炼后合成的改性工程塑料。其中,PC就是聚碳酸脂,ABS就是丙烯腈(A)、丁二烯(B)和苯乙 烯(S)的共聚物。这种改性塑料比单纯的PC和ABS性能更好,例如:抗冲击性提高,耐热性提高,硬度提高等等
