This invention discloses improved mold parts for ophthalmic lenses fashioned from a first thermal plastic resin compounded with a second thermal plastic resin resulting in a thermal plastic compound with a deionized water contact angle that is greater than the deionized water contact angle of either the first thermal plastic resin or the second thermal plastic resin. The mold parts can be used in manufacturing processes, such as, for example: continuous, in-line or batched processes.
