LEXAN™ EXL5689 Resin Opaque Color, Low Temperature Ductility. MVR @ 9

LEXAN™ EXL5689 Polycarbonate Resin is a 9% Glass Fiber Reinforced Polycarbonate Siloxane Copolymer material engineered for applications requiring Flame Retardancy, enhanced Stress Crack Resistance (ESCR), and Structural Stability. This Opaque Grade is designed to perform reliably in Environments where components are exposed to Mechanical Stress, Chemical Contact, and Long-Term Operational Conditions.

In applications where Materials Encounter repeated Stress and Chemical Exposure, maintaining Integrity without Cracking is Essential. This Grade is formulated with improved ESCR Performance, allowing components to Resist Environmental Stress Cracking and retain Functionality over Extended Periods. This supports Long-Term reliability in Harsh Operating Conditions.

A Key Advantage of LEXAN™ EXL5689 Polycarbonate Resin is its 9% Glass Reinforcement, which enhances Stiffness and Load-Bearing capability while maintaining balanced Toughness. This combination allows Parts to Hold Shape under Stress while still Resisting Brittle Failure, making it suitable for demanding Structural and Electrical applications.

The material also delivers Strong Flame Retardant Performance, achieving UL94 V 0 Rating from 1.50 mm to 3.00 mm Thickness, ensuring Compliance with Safety requirements in Electrical and Industrial Environments.

With a Medium Flow Profile (MVR ~9), the Resin offers controlled Molding Behavior, enabling consistent Filling of Molds while maintaining Dimensional Accuracy. This supports reliable Processing, stable Part Geometry, and consistent Production Quality.

Another important benefit is its improved Chemical Resistance, allowing Parts to perform Effectively when exposed to Cleaning Agents, Industrial Fluids, or Environmental Contaminants. combined with its Stress Resistance, this enhances Durability and Service Life in Real World applications.

Despite its Reinforcement, the material maintains good Surface Quality, enabling Parts to achieve a Clean and uniform Appearance. This makes it suitable for components where Functional performance and Visual Consistency are both Important.

The Siloxane-Modified Copolymer Structure enhances Impact Resistance and Low Temperature Ductility, ensuring that Parts maintain Toughness under varying Temperature Conditions and Mechanical Loads.

From a Dimensional Standpoint, LEXAN™ EXL5689 Polycarbonate Resin provides stable Geometry during Molding and Service, supporting accurate Assembly Fit and Long-Term Structural Reliability.

The formulation includes Stabilizers that Help maintain material performance and Surface properties over time, especially under Environmental Exposure.
LEXAN™ EXL5689 Polycarbonate Resin is also RoHS Compliant, aligning with Global Environmental Standards.

In practical use, this Grade is well suited for Electrical Enclosures, Automotive Components, Industrial Housings, and Outdoor Structural Parts where Flame Retardancy, Chemical Resistance, and Crack Resistance are Essential. Its ability to Resist Stress Cracking makes it particularly valuable in applications exposed to Mechanical Load and Environmental Stressors.

At its Core, LEXAN™ EXL5689 Polycarbonate Resin delivers a Powerful combination of Flame Retardancy, Stress Crack Resistance, and Structural Reinforcement. It provides a Dependable Solution for applications requiring Durability, Safety Compliance, and Long-Term performance in demanding Environments.
