Ultem resin delivers a broad range of desirable performance properties for eyeglasses frames. The material offers elasticity coupled with resistance to deformation, allowing the frame to be bent easily yet returned to its original shape. In addition to its intrinsic lightweight of up to 50% compared with metal, Ultem resin is suitable for precision thin-wall molding down to 1.2mm, cutting weight even more. The material can be custom colored to provide a wide range of aesthetic effects. Other potential eyewear applications for Ultem resin include entertainment eyewear (such as 3D glasses) and safety glasses.
