Everyone is doing DVD....... Roehm Introduces PMMA for DVDs nikkeibp.asiabiztech.com German-based Roehm GmbH, a leading manufacturer of methacrylate-based products introduced a Plexiglass solution for optical disks, including digital video discs. Plexiglas has been a trademark product for the company since 1933 and is currently made into products which are used in households, optical and offices, medicine, electronics, buildings, traffic signals, and lighting. Plexiglas DQ501, is a PMMA solution which the company believes is far superior to the polycarbonate that is currently used by most optical disk manufacturers. The solution has a very low birefringence of less than 20 nanometers, 92 percent light transmission, high surface hardness and mar resistance. "The DQ501 is the closest material to glass available and transparency is a vital issue when it comes to products with such high density. It allows the precise reproduction of even the smallest pits," said Dr Hans-J_rgen Kress, senior vice president, PMMA Moulding & Extrusion Compounds/ Pharma Polymers.
