S-Plastics Cycoloy C6840 resin is an injection moldable, flame retardant PC/ABS blend. It contains non-chlorinated & non-brominated flame
retardant systems intended to meet governmental regulations and various voluntary environmental labels. Key features of Cycoloy C6840
resin including very good flow, balanced impact property, heat resistance, hydrolytic stability and all color options make this grade an ideal
candidate for thin wall applications.
