NeoGraf Solutions’ Graf-M™ masterbatches represent a cutting-edge approach to enhancing polymer performance through the incorporation of graphite-based additives. These innovative products combine pelletized masterbatches and dispersions with NeoGraf’s Graf+® graphite powders, Graf-X™ graphene nanoplatelets, and GrafGuard® expandable graphite flakes, offer manufacturers a powerful tool to elevate their materials’ capabilities and simplify the manufacturing process.
Graf-M masterbatches address the growing demand for high-performance polymers in industries such as building and construction, transportation, automotive, and bedding. The products in the Graf-M family are becoming more diverse by utilizing different polymer carriers to generate more compatibility with different polymeric systems. They can also be customized to make specialized products for specific applications. By infusing polymers with graphite additives, these masterbatches unlock enhanced properties that significantly improve end-product performance.
The Graf-M FR™/GrafGuard® infused masterbatch line of fire retarding products has branched out into different polymer systems, including polypropylene, ethylene-vinyl acetate, nylon, and many other elastomeric polymer systems. NeoGraf’s experience of incorporating the GrafGuard expandable graphite flakes makes it possible to offer a highly concentrated masterbatch of flakes with or without synergistic materials in a customized solution for the customers to achieve their flame retardancy goals.
