Lexan* MPX1 polycarbonate (PC) siloxane copolymer resin is a UV stabilized injection molding (IM) grade with release properties. This resin offers good low temperature ductility in combination with high flow characteristics and excellent processability with opportunities for shorter IM cycle times compared to standard IM PC resins. Lexan MPX1 resin is a general purpose product available in limited colors and may be an excellent candidate for a broad range of applications.
All colors are customizable. Refer our ColorXpress tool to check color availability
