LEXAN™ XHT3143 Opaque Color Polycarbonate Resin. Copolymer High Heat
High Flow Performance, Added UV Stabilizer. Extreme High Heat 165°C
LEXAN™ XHT3143 Polycarbonate Resin is an Opaque High Heat Polycarbonate Copolymer engineered for applications requiring Continuous Thermal Resistance Up to 165°C, enhanced UV Stability, and Long-Term Outdoor Durability. This Non-Reinforced Engineering Thermoplastic is designed for Structural components exposed to both Elevated Temperatures and Environmental Weathering Conditions, where sustained performance is Essential.
A Defining Feature of LEXAN™ XHT3143 Polycarbonate Resin is its ability to withstand combined exposure to Heat, Sunlight, and Environmental Stress. With Continuous Service capability Up to 165°C, the material maintains Mechanical Integrity and Dimensional Stability in applications where Thermal Loading and Outdoor Conditions Occur Simultaneously.
To Enhance Environmental Resistance, LEXAN™ XHT3143 Polycarbonate Resin Incorporates UV Stabilization, helping reduce Surface Degradation, Discoloration, and Property Loss caused by prolonged exposure to Natural or Artificial Light. This supports Long-Term material Stability in Outdoor and Semi-Exposed Installations.
The material provides balanced Flow Behavior, enabling consistent Mold Filling and stable Part Formation across a range of Industrial Geometries. This supports Repeatable Manufacturing Quality while maintaining Dimensional Accuracy in Production Environments requiring Consistency and Durability.
The Copolymer Structure delivers reliable Impact Resistance and Structural Stability, allowing components to maintain Shape, Alignment, and Mechanical performance over Extended Service Life. This makes the material suitable for demanding Structural applications where Durability is Critical.
Unlike Transparent XHT Variants, LEXAN™ XHT3143 Polycarbonate Resin is optimized for Opaque Structural and Exterior applications, where Mechanical Reliability, Weather Resistance, and High-Temperature capability are prioritized over Optical Performance.
The material achieves a UL94 HB Rating from 1.50 mm to 3.00 mm Thickness, providing Basic Flame performance for General Engineering applications where enhanced Flame Retardancy is not required. It is also RoHS Compliant, supporting Global Environmental and Regulatory Standards.
Typical applications for LEXAN™ XHT3143 Polycarbonate Resin include Automotive Exterior Components, Industrial Housings, Outdoor Equipment, Electrical Enclosures, and Structural Parts where 165°C Heat Resistance, UV Stability, and Environmental Durability are required.
For Engineers Developing components exposed to both Thermal and Environmental Stress, LEXAN™ XHT3143 Polycarbonate Resin offers a robust Solution Focused on Long-Term Structural Reliability, Weather Resistance, and consistent Processing performance in demanding Outdoor Conditions.
