SD POLYCA™ Grades


CS Series
Abrasion resistant grades

SD POLYCA™ CS series are abrasion resistant grades. These products show high abrasion resistance in addition to high heat resistance, mechanical properties and dimensional stability of polycarbonate resin. These products are suitable to the application where abrasion resistance is required such as gears, bearings and keyboard switches.
