Abstract (en)
[origin: WO2008131329A1] This invention discloses improved mold parts fashioned from a thermoplastic resin compounded with an additive to reduce the surface energy of the mold part (to below 30 mN/m). The mold parts can be used in manufacturing processes, such as, for example: continuous, in-line or batched processes of ophthalmic lens molds.
