Fire performance of glass reinforced polyesters

Abstract

~ Glass reinforced polyesters (GRP), or the resins used, have to pass a wide variety of tests which vary considerably from country to country and from industry to industry. Some of these tests are carried out on a scale outside the capabilities of most laboratories and the results leave much to be desired in the matter of reproducibility. All these factors lead to problems for the formulator of fire-retardant unsaturated polyester resins.
