Showa Denko markets unsaturated polyester resin under the name Rigolac™.

Unsaturated polyester resin is light, strong and highly resistant to corrosion. It is thus used for the matrix in fiber reinforced plastics (FRP), which are used in a wide array of fields ranging from household goods, consumer electronics and automotive parts to marine exploration and development. The molding compounds BMC and SMC offer favorable electrical properties, excellent dimensional accuracy and flame retardancy, and diverse design possibilities. Their use in press molding means less physical strain on workers and results in high productivity.
