Three new grades of weather resistant resins stand up to prolonged outdoor exposure while maintaining their mechanical properties and appearance. Bayblend® W90 XG is an opaque, high flow UV-stabilized polycarbonate/ acrylonitrile styrene acrylate (PC/ASA) resin for injection molding parts that require good surface appearance. While this resin is well suited for most outdoor applications, Bayblend® grade W100 XG resin suits applications that require high thermal resistance. Makroblend® WT203 (PC/polyester) resin features chemical resistance, high impact strength, high heat resistance and high flow.
All three resins can be injection molded or co-injection molded over a substrate material. Makroblend® WT203 retains its impact properties after weathering exposure for a long time. It can replace metal or painted plastic parts in outdoor applications that were previously thought to be unsuitable for PC/polyester blends.
