如何增强PVC塑料型材的抗冲击性能

PVC塑料型材因具有耐腐蚀、耐老化等优良性能而得以广泛应用,但它又是一种坚硬而脆的材料,抗冲击强度较低,加工性能不佳。本文从原材料、混料、设备与模具、配方、加工工艺5个方面对其进行改进,以获得稳定、优良的抗冲击性能。

PVC plastic profiles with corrosion resistance,aging resistance and other excellent performance can be widely used,PVC resin is a hard and brittle material,low impact strength,poor processing performance.This paper from raw materials,mixing,equipment and mold,formulation,processing technology 5 aspects of improvement,in order to obtain a stable,excellent impact performance.
