Latest Patents
Quinlan's latest patents include innovative methods for improving expandable styrene polymer particles. One of his patents focuses on "Antilumping Expanding Styrene Polymers," where expandable styrene polymer particles are surface-coated with calcium polysilicate to prevent lumping during expansion. This coating is achieved by adding 0.02-0.05 parts of calcium polysilicate to an aqueous suspension containing 100 parts of polymer particles after impregnating the mixture with a blowing agent, or by dry-blending polymer particles with the polysilicate.
Another significant patent is for "Fast Cooling Styrene Polymer Foams." This invention involves producing expandable styrene polymer particles that exhibit fast cooling rates during molding. The process includes suspending styrene polymer particles in an aqueous medium and impregnating a blowing agent into the particles in the presence of 0.05 to 0.4 parts of silicone surfactant per 100 parts of polymer particles. The silicone surfactant used is selected from siloxane-oxyalkylene copolymers, which contain specific polysiloxane and polyoxyalkylene blocks.
