耐热PVC树脂

Heat-proof PVC resin

聚氯乙烯树脂的耐热性是加工厂家和用户普遍关心的问题。笔者介绍了提高PVC耐热性的几种途径,如交联、卤化、共混、共聚等。尤其是N—取代马来酰亚胺共聚PVC树脂,既能显著提高耐热性,又有较好的抗冲性。

Some measures for raising the heat- proof capacity of PVC was introduced, such as cross bonding, halogenation, blending and copolymerization. The N- substituted amide copolymerizing PVC resin not only can largely raise the heat- proof capacity, but also has better resistance capacity to impact.
