Polylac® PA-777D High Heat Moderate Impact ABS
POLYLAC PA-777D is an ABS resin designed for high-heat environments. It keeps its shape even at 117°C (under heavy load) and stays tough in both hot and freezing conditions. Its moderate impact strength means it won’t crack under pressure. PA-777D delivers heat resistance, durability, and ease of molding. It’s the go-to ABS resin for manufacturers who need materials that work as hard as their products do.
