Product Description
ASTALOY™ MB2106 is an alloy of Polycarbonate (PC) and Polyethylene Terephtalate (PET) which is suited to injection moulding applications. Offering an exceptional combination of toughness, heat resistance, chemical resistance, rigidity, UV resistance and and processability, typical applications include automotive exterior door handles, outside use electric pump housings, automotive bumper bars and electrical switch junction boxes.

Note: The letters "U" or "W" indicate UV stabilisation has been added [ ie: ASTALOY™ MB2106U ].
