UNSATURATED POLYESTER MOLDING COMPOUNDS - PREMIX (Panasonic)
Polyester resins are unsaturated resins formed by the reaction of dibasic organic acids and polyhydric alcohols. Unsaturated polyester resin dissolved in styrene monomer and benzoyl peroxide was added as the catalyst and re-filling material and glass fibers, and the coloring material is charged and heated to make the unsaturated polyester compound.
