Plastics and Elastomers Functions

Resin

Potential Benefits

Impact: Best-in-class ductility to -60 ºC with an outstanding balance of ductility and viscosity.
Weatherability: Excellent retention of mechanical properties upon outdoor exposure.
Aging: Better retention of properties vs. other polycarbonate resins.
Flame retardance: FR grades can be used in many ECO-compliant applications.
Knitline strength: A significant improvement over PC/ABS material
Chemical resistance: Improved chemical resistance to some chemicals compared to standard polycarbonate
