Expandable graphite is a form of naturally occurring graphite treated with intercalation chemicals like acids or oxidizers. When exposed to high temperatures, it expands significantly due to the release of gases trapped between the graphite layers. This unique property makes it highly versatile for various industrial and commercial applications.Uses and Applications1. Fire Retardants Description: Expandable graphite is widely used as a flame-retardant additive in plastics, coatings, foams, and construction materials. How it Works: Upon exposure to heat, it forms an insulating, protective layer of expanded graphite that prevents the spread of flames and reduces heat penetration. Industries: Building and construction, automotive interiors, electronics. 2. Gaskets and Seals Description: Its excellent thermal and chemical resistance makes expandable graphite ideal for gaskets and seals in industrial applications. Advantages: It withstands high temperatures and harsh chemical environments,
