Products Description

High Expansion Rate Graphite is a flexible graphite product obtained through special modification treatment by our company. It is an ideal new type of sealing material, widely used in dynamic and static sealing in industries such as petroleum, chemical engineering, electric power, aviation, automobile, shipbuilding and instrumentation.

After instantaneous high-temperature treatment,High Expansion Rate Graphite transforms from flake to worm-like shape, with its volume expandable by 100-600 times. This expanded graphite still retains the properties of natural graphite and has good forming plasticity, flexibility, ductility and sealing performance. It is a high-quality raw material for various graphite plates and seals, and can also be used as a new type of protective slag and exothermic agent in the metallurgical industry.

Varieties: 9950250, 9980250, 9950200, 9980200, 9550250, 9580200, etc. Specifications Particle size: 32 mesh, 50 mesh, 80 mesh, 100 mesh, -100 mesh, -200 mesh, -325 mesh

Expansion ratio: 100-600ml/g

Performance:High Expansion Rate Graphite, and the finished products have high temperature resistance, radiation protection, thermal insulation, lubricity, plasticity and chemical stability.
