Plastistrength® 552

Plastistrength® 552 by Arkema is a high molecular weight acrylic polymer. Acts as a processing aid. Provides strong entanglements and higher melt shear process, thus allowing for more homogenous blends and finer blend morphology. Plastistrength® 552 is compatible with blends of polycarbonate and styrenics such as PC/ASA, PC/SAN or PC/ABS. During injection molding, it controls dimensional melt flow and eliminates gate blush, jetting or any "sharkskin" defects that may be introduced by pigments or other polymeric additives.
