Modified plastics | Ensinger

The resulting plastic compounds allow for different (usually increased) thermal, mechanical, electrical, optical or other characteristics to be enhanced beyond what is typically seen in the unmodified base polymer. The most common fillers and additives, besides colourants, are reinforcement fibres, stabilisers, and friction reducing additives.【Get Price】
