Graphite’s endless possibilities never cease to amaze, even the most technically advanced minds in building and construction. Our treated graphite can be inert for years, but when exposed to the heat of a fire, it instantly expands to several hundred times its original volume, providing both a fire-stop and a smoke-suppressing char layer. NeoGraf has created a portfolio of graphite additives, some with fire retardant properties and some with electrical/thermal characteristics for use in putties, coatings, foams, roofing materials, and concrete.

Coatings & Adhesives
NeoGraf’s graphite additives and powders are used in diverse coating and adhesive products and applications. GrafGuard® expandable graphite has long been used as an intumescent material and can be synergistically combined with other chemical and intumescent fire retardant materials to help protect a variety of different substrates. Graf+® graphite powders provide thermal and electrically conductive properties to a variety of coatings for electrostatic dissipation and conductive polymers.
NeoGraf products:
Roofing
NeoGraf’s GrafGuard® expandable graphite materials are used in many different types of roofing systems in various applications. Our materials are non-halogenated, contain no solvents and serve as an intumescent material that can be used alone or in combination with other chemical and intumescent fire retardant materials to improved fire resistance.
NeoGraf products:
Putties & Pastes
Fire stops and caulking materials are increasingly regulated by fire-safety codes to limit fire propagation. GrafGuard® fire-stop graphite flake material is non-halogenated, lead- and chrome-free, used synergistically with other commonly used flame retardants in putties, pastes, caulk and other building materials.
NeoGraf products:
Thermoplastics
NeoGraf’s GrafGuard® expandable graphite materials are available in a variety of onset temperatures, allowing for high processing temperatures required for thermoplastic applications. Our products are non-halogenated, contain no solvents and serve as an intumescent material that can be used alone or in combination with other chemical and intumescent fire retardant materials to deliver improved fire resistance. Additionally, our Graf+ graphite powders bring thermal and electrical conductive properties to thermoplastic formulations.
