PVC复合材料应用研究进展

Research Progress on Application of PVC Composites

PVC树脂是极性非结晶型高聚物,具有阻燃、耐化学性高、电绝缘性好、价格便宜等优点。硬质PVC抗拉、抗弯抗冲击性能较好,软质PVC的断裂伸长率、耐寒性较好,但存在冲击性能差、耐热性差等问题,因此需要经过改良才能使用,改性提升后的PVC复合材料可根据不同特性应用于不同领域。

PVC resin is a polar amorphous polymer,which has the advantages of flame retardant,high chemical resistance,good electrical insulation and low price.Rigid PVC has better tensile,flexural and impact resistance,and soft PVC has better elongation at break and cold resistance,but it has problems such as poor impact performance and lack of heat resistance,so it needs to be improved before it can be used.The modified and upgraded PVC composite materials can be used in different fields according to different characteristics.
