PARALOID™ EXL-2620 modifier is a general purpose MBS core-shell impact modifierproviding an excellent balance of impact resistance and modulus retention in a variety ofengineering resins. Thanks to the core-shell structure and well designed MBS composition,the improvement in impact is obtained without impairing other mechanical properties, suchas 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).
