lexan PC EXL1414 物性

Lexan* EXL1414 polycarbonate (PC) siloxane copolymer resin is a medium flow opaque injection molding (IM) grade. This resin offers extreme low temperature (-40 C) ductility in combination with excellent processability and release with opportunities for shorter IM cycle times compared to standard PC. Lexan EXL1414 resin is a product available in wide range of opaque colors and may be an excellent candidate for a wide variety of applications.
