Clearstrength® 223

Clearstrength® 223 is a methylmethacrylate butadiene styrene (MBS) core-shell impact modifier designed to meet the most demanding impact performances in injection malding, extrusion and calendering opaque PVC applications as well as for ambient and low temperature toughness to engineering polymers. The low temperature impact resistance and easy processability of Clearstrength® 223 impact modifier has made it a leading impact modifier used in CPVC pipe and fittings, furniture films and indoor profiles for over 25 years. This additive also aimed at providing good impact to polycarbonate, polyesters and a variety of polycarbonate blends, in particular PC/ABS.
