LNP™ ELCRES™ EXL7414

1 of 50 products in this brand
SABIC's Specialties Business LNP ELCRES EXL7414 is based on Polycarbonate (PC) siloxane copolymer resin. It is a medium flow, non-chlorinated, non-brominated flame retardant opaque grade. It offers excellent low temperature ductility (-40C), 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 Polycarbonate. It is available in wide range of opaque colors and is an excellent candidate for a wide variety of applications such as the battery cover of fast-charging mobile phones that need to be compliant with IEC62368-1.

Polymer Name: Polycarbonate-Siloxane Copolymer

Additives Included: Flame Retardant, Heat Stabilizer, Mold Release Agent

Processing Methods: Injection Molding

Flexural Modulus: 2130.0 - 2130.0 MPa

Note
  • ᵍ Measurements made from Laboratory test Coupon. Actual shrinkage may vary outside of range due to differences in processing conditions, equipment, part geometry and tool design. It is recommended that mold shrinkage studies be performed with surrogate or legacy tooling prior to cutting tools for new molded article.
  • ᵖ UL ratings shown on the technical datasheet might not cover the full range of thicknesses and colors. For details, please see the UL Yellow Card.
  • ⁷ Injection Molding parameters are only mentioned as general guidelines. These may not apply or may need adjustment in specific situations such as low shot sizes, large part molding, thin wall molding and gas-assist molding.
  • ¹¹ The information stated on Technical Datasheets should be used as indicative only for material selection purposes and not be utilized as specification or used for part or tool design.
