Latest Patents

Lapierre’s latest patents revolve around a method of making a foam injection molded article. This groundbreaking method aims to significantly reduce or eliminate corrosion of the mold element. The process entails dispersing effective amounts of sodium borohydride as the primary chemical blowing agent and a combination of sodium bicarbonate and citric acid as the activation system into a polymer resin to form a mixture. This mixture, when heated, allows the activation system to release water, enabling the sodium borohydride to react with it and produce hydrogen gas. The resultant mixture is then injected into a mold, leading to the expansion of the polymer resin and the formation of a foam article. The patent further encompasses a corresponding chemical blowing agent composition, showcasing his innovative approach to improving manufacturing processes.
