LyondellBasell Industries AF SCA said it has developed an experimental metallocene resin with exceptional clarity that also delivers strong performance.RM2073 is a cost-effective alternative to polycarbonate in injection molding, according to the Rotterdam, Netherlands-based firm. It also is suitable as a replacement for glass and other amorphous, transparent plastics such as polymethyl methacrylate and styrene acrylonitrile.
The new metallocene resin achieves 2 percent haze in a 1-millimeter-thick plaque. Its high melt flow of 40 grams per 10 minutes makes it possible to reduce wall thickness. Improved chemical resistance is also possible, the firm said.
Compared with PC, RM2073 has better environmental stress-crack resistance and requires a lower processing temperature.
LyondellBasell said applications include food and beverage packaging, food-service items, storage containers, CD and DVD cases and technical products.
