LEXAN™ 4251R Unique Opaque Color Polycarbonate Copolymer Resin.

LEXAN™ 4251R Polycarbonate Resin is a High Heat resistant Copolymer Polycarbonate material designed for applications requiring Thermal Stability, Impact Strength, and easy Processing. This Opaque Grade offers a balanced performance Profile, making it suitable for components that must Combine Durability with efficient Manufacturing.

For many Industrial and Consumer applications, Materials need to perform reliably without becoming Difficult to Process. This Grade is formulated to provide Ease of Processing with controlled Flow Behavior, enabling Smooth Mold Filling while maintaining Structural Integrity, supporting efficient Production and consistent Part Quality.

With its optimized Composition, LEXAN™ 4251R Polycarbonate Resin delivers Dependable Heat Resistance and Mechanical Strength, allowing components to operate under Elevated Temperatures without Losing Rigidity. This balance makes it suitable for applications where Moderate to High Heat performance and Impact Durability are both required.

Another Key Feature of this material is its Easy Release Characteristics, which Help Simplify Part Ejection during Molding. This reduces Tooling Stress and supports improved Cycle Efficiency, particularly in High-Volume Production Environments where Consistency is Critical.

Despite its High Heat Capability, the material maintains good Impact Performance, ensuring Parts can withstand Mechanical Stress without Cracking or Failure. This supports reliable performance in applications requiring Durability and Long-Term Mechanical Stability.

LEXAN™ 4251R Polycarbonate Resin is classified as Non UL Rated, making it suitable for applications where Flame Retardancy is not a Primary Requirement. Its formulation supports stable performance across a Variety of use Conditions. In addition, it is RoHS Compliant, aligning with Global Environmental Standards.

In practical applications, this Grade is well suited for Electrical Components, Housings, Consumer Products, and General Industrial Parts where Ease of Processing and Thermal performance must be balanced. Its Opaque Nature also supports consistent Visual appearance in finished Parts.

At its Core, LEXAN™ 4251R Polycarbonate Resin delivers a practical combination of Heat Resistance, Impact Strength, and Processing Efficiency. It provides a Dependable Solution for applications requiring balanced performance and reliable Manufacturing Outcomes.
