Abstract:
1. A component for an air handler or hot air furnace which is the molded product of a molding composition comprising: a) a thermoset resin system comprising an unsaturated polyester which is the product of a condensation polymerization reaction between propylene glycol, dicylcopentadiene and maleic anhydride; wherein the unsaturated polyester is dissolved in a reactive monomer selected from the group consisting styrene, α-methyl styrene, vinyl toluene, divinyl benzene, diallylphthalate, hydroxy ethyl methacrylate, methyl methacrylate, and combinations thereof; wherein the ratio of the reactive monomer to the unsaturated polyester resin is from 5:95 to 50:50; wherein the thermoset resin system is blended with 10% to 50% by weight of the thermoset resin system of a low profile additive selected from the group consisting of polymethylmethacrylate, polyethylmethacrylate, polystyrene, polystyrene copolymers, polyvinyl acetate, polyethylene, saturated polyesters, vinyl chloride-vinyl acetate copolymers, polyurethanes, styrene butadiene copolymers, polycaprolactone, cellulose acetate butyrate and combinations thereof; b) from 10 to 30 wt. % based upon the weight of the molding composition of glass fiber; c) from 0.05 to 5 wt. % based upon the weight of the molding composition of an initiator which initiates a copolymerization of the unsaturated resin and the reactive monomer; d) an antimicrobial agent selected from the group consisting of soluble glass containing silver ions, silver sodium hydrogen zirconium phosphate, 5-chloro-2-(2,4-dichlorophenoxy)phenol, silver zeolite and combinations thereof and e) from 45 to 60 wt. % based upon the weight of the molding composition of a flame retardant composition consisting of aluminum hydroxide, whereby the molding composition when molded meets the standard of UL 723.
