BX IM 81 Impact Modifier
BX IM 81 is an acrylate impact modifier with core- shell structure. It can give PVC outdoor transparent products excellent impact strength and weather resistance.
Feature
Promoting plasticization
Improving impact strength without affecting transparency
Improving Weather Resistance
Application
BX IM 81 can be used in outdoor transparent PVC products, such as corrugated boards, sign boards, building materials, PVC sheets, and membranes, for the unique properties of transparency, weather ability and impact strength.
