LEXAN™ XHT3171 Opaque Color Polycarbonate Resin. Copolymer High Heat

For Complex Thin Wall Features, High Flow. Extreme High Heat 165°C

LEXAN™ XHT3171 Polycarbonate Resin is an Opaque High Heat Polycarbonate Copolymer engineered for applications requiring Continuous Thermal Resistance Up to 165°C, Superior High-Flow Processing, and Advanced Design flexibility for Complex Geometries. Developed as a Non-Reinforced Engineering Thermoplastic, this Grade is optimized for manufacturers who need to Combine Thermal performance with High Productivity Molding Capability.

A Defining Feature of LEXAN™ XHT3171 Polycarbonate Resin is its High Flow Behavior, which enables efficient Filling of Intricate Mold Features, Thin Ribs, and Complex Structural Geometries. This supports Precise Replication of Fine Details, reduced Molding Resistance, and improved Cycle Efficiency, making it highly suitable for Precision Injection Molding and High-Volume Production Environments.

Despite its Emphasis on Processability, LEXAN™ XHT3171 Polycarbonate Resin maintains stable Mechanical performance under Elevated Temperatures. With Continuous Service capability Up to 165°C, the material helps preserve Structural Integrity and Dimensional Stability in applications exposed to sustained Heat and Thermal Cycling Conditions.

The Copolymer formulation provides balanced Impact Strength and Dimensional Control, ensuring components maintain alignment and Functional reliability during Service. This contributes to consistent Assembly performance and Long-Term Durability in engineered Systems.

Positioned as the High-Flow Solution within the 165°C XHT Range, LEXAN™ XHT3171 Polycarbonate Resin is specifically designed to Expand Manufacturing Freedom. It enables Thinner Walls, more Complex Part Geometries, and Higher Design Efficiency without Compromising Thermal Resistance, making it particularly valuable in Advanced Injection Molding applications.

Unlike Flame-Retardant or Specialty Optical XHT Grades, this material Prioritizes Processing Efficiency and Geometric Freedom, offering Engineers a practical balance between Manufacturability and High-Temperature Performance.

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

Typical applications for LEXAN™ XHT3171 Polycarbonate Resin include Automotive Components, Electrical Connectors, Industrial Housings, Precision Molded Parts, and Thin-Wall Structural Designs where High Flow Processing, 165°C Heat Resistance, and Complex Geometry capability are required.

In Engineering applications where Design Complexity often limits material Selection, LEXAN™ XHT3171 Polycarbonate Resin provides a practical Pathway to achieve both Manufacturing Efficiency and High-Temperature Performance, enabling more Advanced and Cost-Effective Product Designs.
