  • The Use of Semi-Crystalline Polymer Binder for Concentrate Master Batches Containing Vulcanization Accelerators, Sulfur or Carbon Black
    Publication number: 20230007840
    Abstract: This invention relates to sulfur, vulcanization accelerator and carbon black master batch formulations comprising either a semi-crystalline propylene-olefin copolymer or a combination of a semi-crystalline propylene-olefin copolymer and a hydrocarbon resin. The semi-crystalline propylene-olefin copolymer or the combination of semi-crystalline propylene-olefin copolymer and hydrocarbon resin imparts a high hardness property to the carbon black, sulfur and accelerator master batch formulations thereby preventing pellet agglomeration during storage and allowing for ease in material handling.
