Inventor(s) include Haneline, Mason, Reames; Williams, Steven, Paul; Kiszka, Mariusz; Cardelli, Camillo; Haveriku, Sara; and Badaladssi, Marco.
The application for the patent was published on June 13, under issue no. 24/2025.
According to the abstract released by the Intellectual Property India: "PVC compositions disclosed herein comprise PVC resin, a co-precipitated rare earth additive, and an inorganic flame retardant. These PVC compositions demonstrate an improved flame retardance and have UL94 classification with a sample thickness of about 0.8 mm of V-2 or higher. The co-precipitated rare earth additive contains a rare earth and one or more of zinc, aluminum, and magnesium, wherein the co-precipitated rare earth additive contains about 5 to about 95% by weight rare earth measured on an oxide basis. The inorganic flame retardant can be ATO, MDH, ATH, or mixtures thereof. The co-precipitated rare earth additive provides improved properties in comparison to an identical PVC composition containing the components of the co-precipitated additive but added to the PVC composition as a blend of these components rather than a co-precipitant."
The patent application was internationally filed on Nov. 14, 2023, under International application No.PCT/US2023/079666.
