Abstract
A glass fiber-filled poly(arylene ether)/polyamide composition exhibits reduced die build-up during profile extrusion. The composition includes specific amounts of polyamide, poly(arylene ether), glass fibers, and polypropylene. The reduced die build-up means that the profile extrusion equipment needs to be shut down and cleaned less often, resulting in a substantial productivity improvement.
