1 “Fillers and Reinforcements” in Plastics Additives, R. Talc can, however, make scratches more visible in a highly filled compound; submicron talcs, surface-treated talcs, and anti-scratch additives can mitigate this effect. In addition, a plastic part may soften, bend, or expand under certain conditions, particularly under a load at an elevated temperature.
