SD POLYCA™ Grades


SD POLYCA™ CR Series
PC/Polyester Alloys (Opaque)

SD POLYCA CR series are PC/Polyester alloy grades. These products have improved chemical resistant property in addition to high impact property and heat resistant property of polycarbonate resin.

For some applications, we prepare glass fiber reinforced grades to satisfy your needs.
