LEXAN™ CFR7431 Transparent Clear Polycarbonate Resin. Thin Wall EFR

LEXAN™ CFR7431 Polycarbonate Resin is a Transparent Copolymer Polycarbonate material engineered for applications requiring Thin Wall Flame Retardancy, UV Stability, and controlled Low Flow Processing. This Non Brominated, Non Chlorinated Grade is designed to deliver reliable performance in Environments where both Durability and Precision are Essential.

In applications exposed to Outdoor Light and Environmental Conditions, maintaining Optical Clarity and material Stability becomes Critical. This Grade Incorporates UV Stabilization, helping preserve Transparency and Mechanical properties over time, supporting Long-Term Visual and Structural Stability in Light-Exposed Environments.

A Distinguishing Characteristic of LEXAN™ CFR7431 Polycarbonate Resin is its Low Flow Profile, which provides Better Control during Molding. This allows for improved Part Definition and reduces the Risk of Flash or Overfilling, making it particularly suitable for applications requiring High Precision and controlled Geometry.

At the same time, the material maintains Strong Thin Wall Flame Retardant Performance, achieving UL94 V 0 Rating from 1.20 mm to 3.00 mm Thickness. This enables Designers to meet Safety requirements while maintaining Compact and Lightweight Designs, supporting efficient Space Utilization without Compromising Fire Safety.

Despite its Emphasis on Precision, the material retains excellent Optical Clarity, allowing its use in applications where Visibility is required alongside Flame Resistance. This makes it suitable for Parts where Inspection, Transparency, and Safety Compliance must Coexist.

From a Processing Standpoint, the Resin supports stable Molding with consistent Shrinkage Behavior. Its controlled Flow Characteristic contributes to improved Manufacturing Consistency and Repeatable Part Quality, especially in components requiring Tight Tolerances.

The Non Halogenated Flame Retardant System aligns with Modern Environmental and Safety Expectations, supporting Cleaner material selection without Compromising Performance.

In practical use, this Grade is well suited for Outdoor Electrical Components, Transparent Safety Covers, Thin Wall Enclosures, and UV-Exposed Structural Parts where Flame Retardancy, Clarity, and Durability are required. Its balance of properties makes it particularly valuable in applications that demand both Precision and Long-Term Environmental Resistance.

At its Core, LEXAN™ CFR7431 Polycarbonate Resin delivers a refined combination of UV Stability, Flame Retardancy, and controlled Processing Behavior. It provides a Dependable Solution for applications requiring Thin Wall Accuracy, Optical Clarity, and reliable performance in Light-Exposed Environments.
