Expandable graphite is a kind of graphite product obtained from high-quality natural flake graphite after special modification treatment. After high temperature transient treatment, it changes from flake shape to worm shape, and the volume expands 100-400 times. This kind of expanded graphite still maintains the properties of natural graphite, and has good molding plasticity, flexibility, ductility and sealing. It is a variety of graphite sheets , High-quality raw materials for seals, can also be used as a new type of protective slag, heating agent in the metallurgical industry, and flame-retardant materials for the fire department.
Graphite conductive (dissipative) heat film is a brand-new conductive (dissipative) heat material with unique crystal grain orientation and conducts (dissipates) heat uniformly in two directions. While shielding the heat source and components, the performance of electronic products is improved. The surface can be combined with metal, plastic, stickers, aluminum foil, PET and other materials to meet more design requirements. The product has high temperature resistance, radiation resistance and good chemical stability. Low thermal resistance (thermal resistance is 40% lower than aluminum, 20% lower than copper), light weight (30% lighter than aluminum, 75% lighter than copper), widely used in various flat panel displays, digital cameras, mobile phones, LEDs and other electronics product.
