Acrylic weatherable impact modifier that delivers very high efficiency combined with high gloss necessary for high output profile extrusion. It maximizes the “process window” in which PVC vinyl compounds can reliably develop optimal physical properties, in particular impact resistance.

用途:

Multifunctional Impact Modifier
All rigid PVC profile extrusions
Complex window lineal profile extrusions, where additional metal release can limit shear-burning issues

优势:

Delivers combination of impact and processing features
Delivers very high efficiency impact
Combined with gloss and increased metal release, necessary for high output profile extrusion
Increased metal release for complicated profiles to limit shear-burning
Processing window maximized to develop: high impact resistance and consistent gloss
Over a wide range of processing conditions/temperatures
Delivers both drop dart and Izod impact performance
