Expandable graphite is a flexible graphite product produced by our company from high-quality natural flake graphite, which has been specially modified. It is an ideal new type of sealing material with extensive applications in dynamic and static sealing in the oil, chemical, electrical, aviation, automotive, marine, and instrumentation industries.
Expansible graphite is treated with high-temperature instantaneous processing, transforming from flake-like to worm-like, with the ability to expand in volume.100-400 times expansion, this expanded graphite still retains the properties of natural graphite, and has good molding plasticity, flexibility, extensibility, and sealing properties. It is a high-quality raw material for various graphite sheets and sealing components, and can also be used as a new type of protective slag and heating agent in the metallurgical industry.
