WEATHERING PERFORMANCE OF A SCRATCH RESISTANT COPOLYCARBONATE RESIN

摘要

The weathering performance of a Lexan copolycarbonate resin was studied against a benchmark PC resin. Known ISO, ASTM and SAE weathering protocols were used and observed differences explained. Lexan* copolycarbonate resin offers a scratch resistant polycarbonate solution that opens up new possibilities in terms of part performance. Key applications range from mobile phones to interior automotive trims and benefit from the elimination of secondary operations due to the increased hardness of the material. This can lead to cost-out opportunities and environmentally friendlier solutions where conventional protective hard coatings or painted surfaces are considered.
