LEXAN™ FST3403 Opaque Color Copolymer Polycarbonate Resin. High Flow
Non-Brominated Non-Chlorinated Flame Resistance for Rail Applications
LEXAN™ FST3403 Polycarbonate Resin is an Opaque Polycarbonate Copolymer material engineered for applications requiring Flame, Smoke, and Toxicity (FST) Compliance, High Flow Processability, and Halogen-Free Safety Performance. This Grade is specifically designed for Rail Transportation applications, where Strict Fire Safety Standards and material reliability are Essential.
In Environments such as Rail Interiors and Passenger Compartments, Materials must Comply with Stringent Fire Safety Regulations. This Grade is developed to meet Multiple International Standards including EN45545 R6 HL3, DIN 5510-2, NFPA 130, and PN-K-02511, ensuring controlled Flame Spread, reduced Smoke Emission, and Low Toxicity, supporting Safe use in Enclosed Public Transportation Environments.
A Key Advantage of LEXAN™ FST3403 Polycarbonate Resin is its High Flow Capability, which enables efficient Molding of Complex and Large Components. This supports improved Manufacturing Efficiency, reduced Cycle time, and consistent Part Quality, especially in High-Volume Production of Interior Panels and Structural Components.
The material features a Non Brominated, Non Chlorinated Flame Retardant System, aligning with Modern Environmental and Safety Regulations. This ensures Cleaner material Composition while maintaining High-Level FST Performance, making it suitable for Regulated applications where Halogen-Free Solutions are required.
Despite its Strong Fire Safety Characteristics, the Resin maintains reliable Impact Strength and Structural Stability, allowing components to perform under Mechanical Stress and Daily Operational use. This ensures Durability and Long-Term performance in Transportation Environments.
From a Dimensional Standpoint, the material provides excellent Shape Stability and Low Deformation, supporting accurate Fit, Assembly Precision, and consistent Performance, particularly in applications Involving Large Molded Parts.
With its balanced Processing Behavior, the Resin enables stable Molding Conditions and Repeatable Part Reproduction. This contributes to Manufacturing Consistency and High-Quality Output, even for Complex Rail Interior Designs.
Unlike Conventional Materials Rated by UL94, this Grade is specifically optimized for FST Certification Standards rather than Typical Vertical Burn Classifications, aligning its performance with Transportation Safety Requirements.
LEXAN™ FST3403 Polycarbonate Resin is also RoHS Compliant, aligning with Global Environmental Standards.
In practical use, this Grade is well suited for Rail Interior Panels, Wall Systems, Ceiling Components, Seat Structures, and Passenger Cabin Elements where Flame, Smoke, and Toxicity Compliance is Mandatory.
At its Core, LEXAN™ FST3403 Polycarbonate Resin delivers a Powerful combination of FST Compliance, High Flow Processability, and Halogen-Free Safety Performance. It provides a Dependable Solution for applications requiring Advanced Fire Safety, efficient Manufacturing, and reliable performance in Transportation Interiors.
