Acrylic copolymer Similar grade:KM355,IM808A,FM-50 It is fit for outdoor rigid PVC product. High impact and weatherability

AIM ZB-21 ZB-50

It shows typical core-shell structure.The core is moderate cross-linked butyl acrylate (BA),the shell is methyl methacrylate which have excellent compatibility with PVC resin,The shell can absorbe and disperse the energy added to PVC rigid product caused by impact. It has excellent properties of impact and low temperature resistance.

It is especially suitable for outdoor rigid and semi-rigid PVC product and those products which have high request on impact and weatherability.

It is amorphous white flowing powder. It can be dissolved in ketone and chlorinated hydrocarbon,but not in wanter and alcohol.
