BASF Polyurethanes GmbH has introduced an anti-static polyurethane granular masterbatch. Elastostat is a permanent anti-stat that does not require specific ambient conditions such as humidity, claims the Lemforde, Germany, firm. The product processes easily and is highly compatible with standard plastics such as polyethylene, polypropylene, polystyrene and ABS. It takes on the color of the plastic in which it is dispersed. BASF said usage levels vary from 7.5 to 15 percent by volume for the masterbatch. Properties are minimally affected, the company claims.
