LNP™ ELCRIN™ EXL8281TCC

LNP™ ELCRIN™ EXL8281TCC is a polycarbonate (pc) siloxane copolymer resin with 75% post-consumer recycled (pcr) content, designed for transparent injection molding applications. This resin offers excellent low-temperature ductility (-10~-20 °C), combined with medium flow characteristics and outstanding processability, potentially reducing injection molding cycle times compared to standard PC. Available in both transparent and opaque colors, this is a versatile product suitable for a wide range of applications.

Brand: LNP™ ELCRIN (71 products)

Polymer Name: Polycarbonate-Siloxane Copolymer

¹ 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.
² 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.
³ 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.
⁴ 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.
