LightFair International Technical Innovation Award

This award-winning moldable silicone provides excellent properties and secondary optics solutions for LED lamp/luminaire applications. Its curing speed is optimized for the injection molding process of silicone rubber, enabling production of plastic-like, smooth surface optics with comparatively high hardness and low surface friction. Its high light transmittance with low attenuation coefficient – combined with high Abbe number – enables lighting companies to design optics for luminaires with high lumen efficiency. High thermal stability ensures the retaining of high transparency – even in harsh environments.
