LEXAN™ XHT2171 Opaque Color Polycarbonate Resin. Copolymer High Heat

For Complex Thin Wall Features, High Flow. Extreme High Heat 155°C

LEXAN™ XHT2171 Polycarbonate Resin is an Opaque High Heat Polycarbonate Copolymer engineered for applications requiring Continuous Thermal Resistance Up to 155°C, Exceptional High-Flow Processing, and Advanced Design Freedom for Complex Geometries. This Non-Reinforced Engineering Thermoplastic is optimized for manufacturers who Prioritize Moldability, Precision Detailing, and High-Volume Production Efficiency within the XHT High-Heat material Platform.

A Defining Feature of LEXAN™ XHT2171 Polycarbonate Resin is its very High Flow Performance, which enables efficient Filling of Intricate Mold Features, Thin Ribs, and highly Detailed Geometries. This supports accurate Replication of Fine Structures, reduced Injection Pressure Requirements, and improved Manufacturability in Precision Molding applications.

Despite its Strong Emphasis on Processability, LEXAN™ XHT2171 Polycarbonate Resin maintains reliable Structural performance under Elevated Temperature exposure Up to 155°C. This allows components to retain Shape Stability and Functional Integrity in Systems Experiencing sustained Heat or Localized Thermal Buildup.

The material provides balanced Impact Resistance and Dimensional Stability, ensuring Molded Parts maintain alignment and Durability during Service. This contributes to consistent Assembly performance and reliable Operation in Technical and Industrial Environments.

Positioned as the Highest-Flow Member of the 155°C XHT family, LEXAN™ XHT2171 Polycarbonate Resin is specifically designed to Expand Manufacturing Capability. It enables Thinner Wall Sections, more Intricate Design Features, and improved Cycle Efficiency without Sacrificing Core Thermal Performance.

Unlike Higher-Temperature XHT Grades, this material Prioritizes Processing Efficiency and Geometric Complexity, making it especially suitable for applications where Design Freedom and Productivity are Primary Drivers.

The material is not UL94 Rated, Reflecting its Focus on Thermal and Processing performance rather than Flame-Retardant Classification. It is also RoHS Compliant, supporting Global Environmental and Regulatory Standards.

Typical applications for LEXAN™ XHT2171 Polycarbonate Resin include Automotive Components, Electrical Connectors, Industrial Housings, Precision Molded Parts, and Thin-Wall Structural Designs where High Flow Capability, 155°C Heat Resistance, and Complex Geometry Manufacturing are required.

For Engineers seeking to Maximize Moldability within a High-Heat material System, LEXAN™ XHT2171 Polycarbonate Resin delivers a Strong balance of Processing Efficiency, Design Freedom, and Thermal Stability, enabling Cost-Effective Production of highly Detailed Components.
