LEXAN™ XHT2143 Opaque Color Polycarbonate Resin. Copolymer High Heat
High Flow Performance, Added UV Stabilizer. Extreme High Heat 155°C
LEXAN™ XHT2143 Polycarbonate Resin is an Opaque High Heat Polycarbonate Copolymer engineered for applications requiring Continuous Thermal Resistance Up to 155°C, enhanced UV Stability, and reliable Processing Performance. This Non-Reinforced Engineering Thermoplastic is designed for components Operating in Environments where Moderate High Heat exposure and Outdoor Conditions must be Managed Simultaneously.
A Key Feature of LEXAN™ XHT2143 Polycarbonate Resin is its ability to maintain performance under combined exposure to Heat and Environmental Weathering. With Continuous use capability Up to 155°C, the material supports Dimensional Stability and Mechanical Integrity in applications where sustained Thermal Load and Outdoor exposure Occur together.
To Improve Outdoor Durability, LEXAN™ XHT2143 Polycarbonate Resin Incorporates UV Stabilization, helping reduce Discoloration, Surface Degradation, and Property Loss caused by Prolonged exposure to Sunlight or Artificial Lighting. This ensures consistent Mechanical performance and Surface appearance throughout Long Service Life in Outdoor Environments.
The material provides balanced Flow Characteristics, enabling stable Mold Filling and consistent Part Formation across a range of standard and Moderately Complex Geometries. This supports efficient Manufacturing while maintaining Repeatable Dimensional Accuracy and Part Quality.
The Copolymer Structure delivers reliable Impact Resistance and Dimensional Stability, allowing Molded components to maintain Shape and alignment during Service. This contributes to Dependable performance in applications requiring both Structural Durability and Environmental Resistance.
Unlike Higher-Temperature UV-Stabilized XHT Grades, LEXAN™ XHT2143 Polycarbonate Resin is Positioned as a 155°C-Capable Outdoor performance Solution, offering a practical balance between Thermal Capability, UV Resistance, and Processing Efficiency.
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™ XHT2143 Polycarbonate Resin include Automotive Exterior Components, Electrical Housings, Industrial Enclosures, and Outdoor Equipment where 155°C Heat Resistance, UV Stability, and consistent Manufacturability are required.
For Designers seeking a Dependable Outdoor-Grade High Heat Material, LEXAN™ XHT2143 Polycarbonate Resin provides a balanced Solution combining Thermal Endurance, Weather Resistance, and stable Processing performance in a Cost-Effective Engineering Platform.
