SITRAPLAS is expanding its proven EN-Light product line for lighting applications with a comprehensive All-Color UL listing. The listing also covers a wide viscosity range for processing via injection molding and extrusion. The light-diffusing polycarbonate compounds meet the UL 94 V-0 classification at wall thicknesses of 1.5 and 3.0 millimeters. As a result, this material family combines a wide variety of colors with uniform light diffusion, reliable flame retardancy, and flexible processing properties. The EN-Light product family will be showcased at FAKUMA 2026 in Hall B4, Booth B4-4501.

A Wide Range of Color Concepts for Lighting Applications

Within the listed material platform, a variety of color options can be created and adapted to the specific lighting application. The material platform enables the creation of a wide range of translucent color options, ranging from neutral and white variants to smoked glass variants and even intense signal and corporate colors. At the same time, light transmission and light diffusion can be specifically tailored to the requirements of the respective application.

This results in application-specific material solutions in which the optical and technical properties are tailored to one another. The light-diffusing compounds enable uniform light distribution and can reduce visible LED hotspots. When formulating the material, the specific component geometry, the light source used, and the desired lighting effect are taken into account.

Wide viscosity range for injection molding and extrusion

The viscosity range covered by the UL listing allows for the selection of suitable flow properties for different part geometries and processing methods. Low-viscosity, high-flow formulations are particularly well-suited for complex or thin-walled injection-molded parts. Higher-viscosity formulations are designed to meet the requirements of various extrusion processes.

The EN-Light material platform is suitable for applications including conventional and thin-wall injection molding, injection stamping , as well as multi-component and insert molding. In the field of extrusion, the range of applications includes the production of profiles, tubes, and sheets, as well as coextrusion. The further processing of extruded semi-finished products via thermoforming can also be taken into account during material design.

Wide Range of Applications

Typical applications include technical lighting fixtures, light profiles, and light strips, as well as applications in the electrical and electronics industries. Other potential applications include household appliances, industrial electronics, e-mobility and charging infrastructure, and illuminated functional and design elements.

In addition, EN-Light is suitable for architectural lighting solutions and decorative lighting applications.

Application-Specific Material Development

In addition to the listed material platform, SITRAPLAS develops application-specific compound variants. In addition to viscosity, color, transmission, and light scattering, other technical properties can be tailored to the requirements of the respective component and its intended application.
