GrafGuard®Expandable Graphite Flakes
GrafGuard® expandable graphite flake is a non-halogenated fire retardant additive for materials that require improved fire-protection characteristics. It can be found in building materials and automotive applications to meet increasingly stringent fire safety codes. GrafGuard materials also improve the performance of fire-retardant additives such as phosphates, magnesium hydroxide and nitrogen compounds.
Upon exposure to high temperatures, the GrafGuard material expands and forms a graphite char layer that is more resistant to degradation than the carbon chars formed from typical chemical intumescent materials. GrafGuard material is manufactured without the lead or chromium that can be found in some other expandable graphite solutions.
GrafGuard flake has been shown to expand up to eight times more than competitive products, exhibiting superior performance even at low temperatures. This high expansion makes it possible to reduce loading levels and improve performance.
GrafGuard expandable graphite is suitable for use in many markets and applications, including:
Consumers and legislators alike continue to demand that manufacturers produce products that reduce human and environmental exposure to greenhouse gases, heavy metals, and other toxic substances. This is driving a variety of industries to search for high performing, cost-effective, nontoxic fire-retardant additives and solutions. The versatility, consistency, superior expansion performance, and high quality of GrafGuard expandable graphite as the only non-halogenated expandable graphite material sourced in North America make it a premier solution for a variety of applications.
GrafGuard materials are offered in a range of onset temperatures, a range of expansion rates and a variety of particle sizes to meet your unique application requirements.
