Expanded Graphite Yarn

Expanded graphite yarn made from flexible graphite and reinforced fibers or metal wires, designed for manufacturing high.....


Expanded Graphite Yarn is engineered from flexible graphite as the primary material and produced through a specially designed processing method. During manufacturing, flexible graphite is combined with selected natural fibers, synthetic fibers, or metal alloy wires, together with suitable binding agents, to form reinforced graphite yarns with controlled strength and flexibility. This process enables the production of graphite yarns tailored for different sealing requirements.

Expanded graphite yarns serve as the essential raw material for manufacturing flexible graphite packings, which are widely used for sealing applications under varying media, temperatures, pressures, and operating conditions.
