PARALOID™ EXL-2620 (Powder)

General purpose MBS core-shell impact modifier providing an excellent balance of impact resistance and modulus retention in a variety of engineering resins. Due to the core-shell structure and well designed MBS composition, the improvement in impact is obtained without impairing other mechanical properties, such as modulus and heat distortion temperature, and with a minor effect on weatherability. Improved impact properties can be expected in the following engineering resins: polycarbonate and its blends (PC/PBT, PC/ABS, PC/PET) and polyesters (PET, PBT). The notch sensitiveness and thick wall brittleness of polycarbonate can be significantly improved with the addition of PARALOID™ EXL-2620 modifier. Not only can the toughness of PC/ABS be improved with PARALOID™ EXL-2620 modifier, but better phase compatibility and less shear surface marks can also be achieved. It finds utility in a variety of conversion processes typically encountered for engineering resins, including extrusion, injection molding, blow molding, and thermoforming.
