LEXAN™ XHT2146 Opaque Color Polycarbonate Resin. Copolymer High Heat

High Flow Performance, Improved Easy Release. Extreme High Heat 155°C

LEXAN™ XHT2146 Polycarbonate Resin is an Opaque High Heat Polycarbonate Copolymer engineered for applications requiring Continuous Thermal Resistance Up to 155°C, optimized Processing Efficiency, and enhanced Mold Release Performance. This Non-Reinforced Engineering Thermoplastic is designed for manufacturers seeking a reliable balance between High-Temperature capability and Stable, High-Volume Production Performance.

A Key Characteristic of LEXAN™ XHT2146 Polycarbonate Resin is its ability to maintain Mechanical Stability under sustained Elevated Temperatures. With Continuous use capability Up to 155°C, the material supports consistent Structural performance in Environments where Heat Build-up or Prolonged Thermal exposure is Present.

Unlike High-Flow Variants Focused on Maximizing Design Complexity, LEXAN™ XHT2146 Polycarbonate Resin is optimized for Processing Stability and Manufacturing Efficiency. The material provides controlled Flow behaviour that supports reliable Mold filling across a Wide range of standard and Moderately Complex Geometries, enabling consistent Part Quality in Production Environments.

A Defining Advantage of this Grade is its enhanced Easy Release Performance, which Improves Demolding behavior by reducing Adhesion between the Part and Tooling Surfaces. This helps Minimize Cycle Interruptions, reduce Tool Wear, and Improve Overall Production Efficiency, particularly in High-Volume Manufacturing Operations.

The Copolymer formulation delivers balanced Impact Resistance and Dimensional Stability, ensuring components maintain Structural Integrity and alignment throughout their Service Life. This contributes to Dependable Assembly performance and consistent Long-Term Functionality in Technical applications.

Positioned as a Processing-Optimized Member of the 155°C XHT family, LEXAN™ XHT2146 Polycarbonate Resin is specifically developed for applications where Cycle Stability, Mold Efficiency, and Production reliability are as important as Thermal Resistance.

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™ XHT2146 Polycarbonate Resin include Automotive Components, Electrical Housings, Industrial Equipment, and High-Temperature Structural Parts where 155°C Heat Resistance, Easy Release Behavior, and consistent Manufacturability are required.

For manufacturers Prioritizing Uptime, Tool Efficiency, and stable High-Temperature Processing, LEXAN™ XHT2146 Polycarbonate Resin provides a Dependable Solution that enhances Production performance without Compromising Thermal Durability.
