LEXAN™ Copolymer EXL1444
SABIC's Specialties Business LEXAN™ Copolymer EXL1444 resin is a medium flow opaque injection molding (IM) grade suitable for FDA compliant applications. This resin offers extreme low temperature (-40°C) ductility, exhibits excellent processability and release with opportunities for shorter IM cycle times compared to standard PC. Lexan EXL1444 resin is a product available in wide range of opaque colors and may be an excellent candidate for a wide variety of food contact applications. This product does not contain PFAS intentionally added during SHPP’s manufacturing process and are not expected to contain unintentional PFAS impurities. Each user is responsible for evaluating the presence of unintentional PFAS impurities.
