LEXAN™ EXL4016H Opaque Polycarbonate Copolymer Resin. Good Impact
Unique Hydrolytic Stability. 6% Glass Reinforced with High Stiffness
LEXAN™ EXL4016H Polycarbonate Resin is a 6% Glass Reinforced Polycarbonate Siloxane Copolymer developed for applications requiring Structural Stiffness, Hydrolytic Stability, and Chemical Resistance. This Opaque Engineering Thermoplastic is designed for Environments where Mechanical Loading and Moisture exposure Occur Simultaneously, and Long-Term Dimensional Stability is Critical.
In applications exposed to Humidity, Water Contact, or Fluctuating Environmental Conditions, LEXAN™ EXL4016H Polycarbonate Resin maintains Mechanical Integrity through enhanced Hydrolytic Stability. This helps preserve Stiffness and Structural performance over time, reducing the Risk of Property Loss in Moisture-Rich Operating Environments.
A Defining Feature of LEXAN™ EXL4016H Polycarbonate Resin is its 6% Glass Reinforcement, which significantly Increases Stiffness and Load-Bearing capability compared to Unreinforced Polycarbonate Grades. This Reinforcement enables improved Resistance to deformation under sustained Mechanical Stress, supporting Structural applications where Rigidity is Essential.
Unlike High-Flow Grades in the EXL family, LEXAN™ EXL4016H Polycarbonate Resin is formulated with a High Viscosity Profile, providing greater Melt Strength during Processing. This Improves Control in Thicker Sections and Structural Geometries, supporting Dimensional Accuracy and reducing Risk of Flow-Related Defects.
The Siloxane-Modified Copolymer Backbone contributes to Impact Resistance and Toughness, allowing components to withstand Dynamic Mechanical Loads while maintaining Long-Term Durability. combined with Chemical Resistance, this supports stable performance in Industrial and Automotive Environments.
From a Processing Perspective, LEXAN™ EXL4016H Polycarbonate Resin delivers stable Molding behavior even with Reinforcement Content, enabling consistent Shrinkage Control and reliable Part-To-Part Repeatability. This is particularly important in Structural components where Dimensional Precision directly Impacts Assembly Performance.
The Opaque formulation supports applications requiring Non-Transparent, uniform Appearance, while maintaining Mechanical and Environmental Robustness across Service Conditions.
The material is classified as Non UL Rated and is RoHS Compliant, aligning with Regulatory requirements where Flame Retardancy is not a Primary Design Constraint but Environmental Compliance remains Important.
Typical applications for LEXAN™ EXL4016H Polycarbonate Resin include Automotive Structural Components, Industrial Housings, Electrical Enclosures, and Outdoor Equipment where Stiffness, Moisture Resistance, and Long-Term Mechanical reliability are required under Environmental Exposure.
Rather than Prioritizing a Single performance Attribute, LEXAN™ EXL4016H Polycarbonate Resin is best Understood as a Structural Reinforcement material for Humid and Mechanically demanding Environments, where maintaining Rigidity and Dimensional Stability over Service Life is the Primary Engineering Requirement.
