Dow Plastics recently demonstrated the technical performance of its new PCHE resin at DVD molding trials completed in cooperation with Axxicon Moulds Eindhoven. According to Merijn Voets, manager development & engineering, Axxicon, “PCHE performed to all our expectations in the molding process.” Voets says the new discs were extremely flat, with good pit replication and virtually no birefringence.

The PCHE resin was processed at very low melt (300-320C) and mold temperatures (50-60C). PCHE has exceptional optical purity and clarity, with a refractive melt index of 1.51 and light transmittance across a full spectrum. The trials were completed on equipment currently used for molding DVD discs, indicating that PCHE can be incorporated into existing manufacturing processes.
