GPPS产品冲击强度的影响因素和优化措施

Affecting factors and improvement on impact property of GPPS

分析影响通用聚苯乙烯(GPPS)产品冲击强度的因素,提出了提高GPPS产品冲击强度的有效措施。质量跟踪结果表明,改进后的GPPS的加工和机械性能明显改善。

This paper analyzed the key factors affecting the impact strength of the general purpose polystyrene (GPPS). An effective measure was presented and adopted for improving the impact property of the GPPS. The result showed that the processing and mechanical properties of the GPPS prepared with the adjusted recipe and technological parameters were obviously improved.
