Unsaturated Polyester Resins
Viscosity can be used as pass/fail criteria for those UPRs that go through several reactions before they are put into pelletized, sheet, or granular form. These basic polymers then can be filled with fibers (typically spun glass) and formed into shapes like watercraft hulls or car fenders. Unfilled versions of these polymers can be pigmented or combined with other polymers to form composites which become solid objects like bowling balls and counter top surfaces.
