LEXAN™ CXT19EX Transparent Polycarbonate Resin. Copolymer High Heat

Low Plateout, Transparent Clear. Vicat Softening Temperature of 190°C

LEXAN™ CXT19EX Polycarbonate Resin is a High Heat Copolymer Polycarbonate material engineered for applications requiring Ultra High Thermal Resistance, Optical Clarity, and Clean Processing Performance. With a Vicat Softening Temperature of 190°C, this Grade is designed to deliver reliable performance in Environments where Elevated Heat and Manufacturing Cleanliness are Equally Critical.

In Precision Manufacturing Environments, material Cleanliness can directly Influence Product Quality and Equipment Uptime. This Grade is formulated with Low Plate-Out Characteristics, minimizing Residue Build-Up on Molds and Processing Equipment. This supports Cleaner Production Cycles and reduced Maintenance Intervals, especially in Continuous or High-Volume Manufacturing Environments.

A Key Strength of LEXAN™ CXT19EX Polycarbonate Resin is its ability to maintain Optical Clarity under Extreme Thermal Conditions, allowing Transparent components to retain both appearance and performance at Elevated Temperatures. This supports applications where Visual Quality and Heat Resistance must Coexist without Compromise.

Compared to other High-Heat Copolymer Grades, this material combines 190°C Vicat performance with enhanced Processing Stability, enabling reliable Molding across a Wider Processing Range. Its Broad Processing Window allows flexibility in Machine Settings, helping reduce Defects and Improve Manufacturing Consistency and Process Robustness.

The Resin also Demonstrates Limited Yellowing Behavior, ensuring consistent Transparency even after repeated Thermal Cycling. This is especially valuable in applications where Long-Term Optical Stability and Product appearance are Essential.

Despite its High Thermal Capability, the material maintains Strong Dimensional Stability, allowing Parts to retain their Geometry under both Processing and Operating Conditions. This supports Precision Fit, Alignment, and Structural Integrity in Complex Assemblies.

LEXAN™ CXT19EX Polycarbonate Resin is classified as Non UL Rated, making it suitable for applications where Flame Retardancy is not the Primary Requirement but High Temperature performance is Essential. In addition, it is RoHS Compliant, aligning with Global Environmental Standards.

In practical use, this Grade is well suited for High Temperature Optical Components, Medical Devices, Data Storage applications, Industrial Equipment, and Precision Transparent Parts where both Purity and Thermal performance are Critical. Its Low Plate-Out behavior makes it particularly Advantageous in Clean and Sensitive Manufacturing Environments.

At its Core, LEXAN™ CXT19EX Polycarbonate Resin delivers a Premium combination of Ultra High Heat Resistance, Clean Processing Behavior, and Optical Stability. It provides a Dependable Solution for applications requiring Maximum Thermal capability with consistent Manufacturing and Visual Performance.
