Features & Benefits

Superior Clarity with UV Guard

This optical-grade LEXAN OQ4120R resin offers over 88% light transmission with minimal haze, and its integrated UV cut-off up to 400 nm protects products and users from sun damage, ideal for lenses and protective covers.

High Impact Resistance

With excellent notched impact strength, components made from this resin withstand drops, impacts, and stress, reducing breakage and replacement costs in eyewear and visors.

Easy Processing with Mold Release

The compound includes a mold release agent and has predictable shrinkage, allowing for faster cycle times, easier demolding, and higher production efficiency in injection molding.
