LEXAN™ XHT1171 Opaque Color Polycarbonate Resin. Copolymer High Heat

For Complex Thin Wall Features, High Flow. Extreme High Heat 145°C

LEXAN™ XHT1171 Polycarbonate Resin is an Opaque High Heat Polycarbonate Copolymer engineered for applications requiring Continuous Thermal Resistance Up to 145°C combined with Exceptional High-Flow Molding Capability. This Non-Reinforced Engineering Thermoplastic is optimized for Detailed, Thin-Wall, and Geometrically Complex Part Designs, where both Thermal performance and Mold Fill behavior are Critical.

A Defining Feature of LEXAN™ XHT1171 Polycarbonate Resin is its Superior Flow Performance, which enables efficient Filling of Intricate Mold Sections such as Fine Ribs, Micro Features, and Long Flow Paths. This Improves Replication Accuracy and supports stable Production in High-Precision Injection Molding Environments.

With Continuous Service capability Up to 145°C, the material maintains Structural Integrity under Elevated Thermal Exposure, allowing components to retain Shape and Function in applications where Heat Generation or sustained Temperature Loading is Present.

The Copolymer Structure provides balanced Impact Resistance and Dimensional Stability, ensuring consistent Part Geometry and reliable Mechanical performance throughout the Service Life. This supports stable Assembly behavior in both Technical and Industrial Systems.

Compared to standard High-Heat Grades in the XHT family, LEXAN™ XHT1171 Polycarbonate Resin is specifically Positioned to Maximize Flow Efficiency and Design Freedom, enabling Thinner Sections and more Complex Part Architectures without Sacrificing Thermal Capability.

This material is not formulated for Flame-Retardant applications and Therefore Carries No UL94 Rating, Reflecting its Focus on Thermal performance and Processability rather than Fire Classification. It is also RoHS Compliant, aligning with Global Environmental and Regulatory Requirements.

Typical applications for LEXAN™ XHT1171 Polycarbonate Resin include Electrical Connectors, Automotive Components, Compact Housings, Industrial Parts, and Thin-Wall Structural Designs where 145°C Heat Resistance, High-Flow Molding, and Dimensional Precision are required.

For Engineers working with Complex Geometries at Elevated Temperatures, LEXAN™ XHT1171 Polycarbonate Resin provides a Processing-Optimized material Platform that Prioritizes Moldability, Design Freedom, and reliable Thermal performance in Compact Part Architectures.
