MS
Summary
Toyo MS is a styrene-methyl methacrylate copolymer : an excellent resin having a well-balanced combination of the good moldability, low water absorption coefficient and high refraction factor of polystyrene and the high transparency, good weather resistance, high hardness and other properties inherent in polymethyl methacrylate.
Applications
lenses, precision optical parts, Lighting fixture covers, medical devices, cosmetics cases, decorative panels, etc.
