Produced by the chemical treatment of quality flake graphite, expandable graphite achieves an increased volume when exposed to rapid, intense heating. The resultant material can be re-compressed into a flexible, tough, and heat- and chemical-resistant sheet with a high degree of cohesive integrity. Expandable graphite is also used as an active, char forming fire retardant in non-structural polymers and in coatings.Through a rigorously-selected chain of global sources, and our unparalleled quality checks, Asbury is the top choice for the expandable graphite used in critical conductive and fire-retardant applications. Our post-production process, combined with unique storage facilities, ensures that your expandable products are properly size and contaminant-free. Asbury's expandable graphite products are manufactured without chromic acid or hexavalent chromium.
