LNP™ ELCRIN™ EXL7414B

Sustainable Grade

ELCRIN EXL7414B polycarbonate (PC) siloxane copolymer resin is a medium flow, non-chlorinated, non-brominated flame retardant opaque grade with major component synthesized from Bio source. This resin offers excellent low temperature ductility (-40ºC), extremely thin wall flame retardant capability with UL94 V0 at 0.6mm, and in combination with excellent processability and release with opportunities for shorter cycle times compared to standard PC. ELCRIN EXL7414B resin is a product available in wide range of opaque colors and excellent candidate for a wide variety of applications, such as the battery cover of fast-charging mobile phones that need to be compliant with IEC 62368-1.
