PVC impact modifier according to its function and modification characteristics for glassy amorphous PVC modifier, can be divided into 6 groups:
① High impact resistance modifier: used in opaque impact resistance mixture.
② Transparent impact resistance modifier: when optical properties and impact resistance are required, use this modifier.
③ Thermal deformation modifier: used to improve the processing temperature range of PVC mixture.
④ Common modifier: used to improve impact resistance, high temperature strength and low temperature flexibility.
⑤ Weather resistance modifier: the use of the modifier in outdoor applications can prevent uv photodegradation.
⑥ Processing AIDS: improve the melt performance of PVC by reducing the melting time.
