Properties of an extremely clean high-flow acrylic resin are discussed in the context of the optical disc market. Benefits include reduced birefringence and light-scattering in parts molded from this resin. Comparisons to standard acrylics and to polycarbonate resins are made. Data from a light-scattering particle counter illustrates improvements in resin purity.
