production process of compound articles and organic peroxide formulation. production process of composite articles, which comprises the steps of: a. supply of a curable mixture comprising: - 30-95% by weight of filler material; - 5-70% by weight of resin, selected from unsaturated polyester resins, vinyl ester resins, (meta) acrylate resins and their combinations; - 0.5-10 phr of at least one peroxyester; and - 0.1-2.0 phr of at least one organic hydroperoxide; wherein the weight ratio between peroxyester and organic hydroperoxide is less than 14.0; and wherein the curable mixture is essentially free of ketone peroxide; B. mixing modeling; and c. heating the molded mixture under temperature in the range of 60-100 ° C to affect the hardening of the resin and the formation of article. |
