ELCRES™ CRX5421 PC/PBT Resin Opaque Chemical Resistance Ductility

Medium Flow, High Ductility and Custom Colorable. UL94-HB Rated

LNP™ ELCRES™ CRX5421 Resin is a Semi Crystalline Polycarbonate Copolymer and PBT Opaque Blend engineered for applications that demand a Strong Balance of Chemical Resistance, Toughness, and Ease of Processing. This LNP ELCRES CRX5421 Grade delivers Medium Flow characteristics combined with High Ductility, making it suitable for complex molded Parts where Durability and Dimensional Stability are Critical. Its Opaque appearance and Custom Colorable capability support both Functional and Aesthetic requirements in demanding Industrial Environments.

Designed for enhanced Performance under aggressive conditions, LNP™ ELCRES™ CRX5421 Resin offers Excellent Resistance to a Wide Range of Chemicals, Significantly reducing the risk of Environmental Stress Cracking. as Part of the LNP™ ELCRES™ Copolymer CRX Series, this material is specifically developed to withstand Harsh Environments where conventional Polycarbonate materials may fail. The Semi Crystalline PC/PBT Structure contributes to improved Resistance against Oils, Cleaners, and Other Industrial Chemicals.

LNP ELCRES CRX5421 is UL94 HB Rated, with a Flammability Classification of UL94-HB from 0.75 mm to 3.00 mm thickness, supporting its use in applications where Basic Flame Resistance is required. The Medium Flow behavior enables efficient processing while maintaining High Ductility, allowing Molded components to absorb Impact and Mechanical Stress without premature failure. These Properties make the material suitable for Housings, Covers, and Functional Structural Components.

Available in Opaque Colors, LNP™ ELCRES™ CRX5421 Resin provides Design Flexibility for Manufacturers seeking both Performance and Visual Consistency. Its combination of Chemical Resistance, Ductility, and Reliable processing performance makes it a preferred Choice for Automotive, Electrical, and Industrial applications exposed to Chemicals and Mechanical Stress. LNP ELCRES CRX5421 Stands out as a Robust Polycarbonate Copolymer Solution for Long Term Reliability in challenging operating conditions.
