Industry Application

Unsaturated Polyester Resin

Unsaturated polyester resin is the most important production of composite materials, mainly glass fiber–reinforced plastics (FRP), but also for casting resins (nonreinforced).

FRP composites are consumed primarily by the construction, marine, and land transportation industries, although they find use in a variety of other applications.

Nonreinforced cross-linked unsaturated polyester resin is used to make cultured marble and solid-surface countertops, gel coats, automotive repair putty and filler, and other items such as bowling balls and buttons.
