“The recent sharp increase in crude oil and derivative products has put increased pressure on the price of all polyester raw materials," explains Steve Wetzel, National Sales Manager, Interplastic's Thermoset Resins Division. "We can no longer absorb these increased costs and must pass a portion on to our customers.”

Interplastic’s Thermoset Resins Division is the manufacturer of CoREZYN and Silmar brand unsaturated polyester, vinyl ester and speciality resins, gel-coats, and colorants for the composites, cast polymer, and solid surface industries.
