A: Company profile

     L.T Graphite has a comprehensive product and technology portfolio that focuses on four fields of graphite - ultrafine particle graphite mould, graphite electrode, graphite crucible, as well as other products mainly made of graphite.
     Graphite materials exhibit unique properties such as good electrical and thermal conductivity, heat and corrosion resistance, low friction, and reduced weight while at the same time maintaining high strength. Due to the shortage of energy and raw materials, our high performance products made from graphite are in increasingly high demand in industries. They also play a progressively important role in everyday life, thereby substituting traditional materials.





B: our products

Graphite paper: It is made of high-carbon phosphor flake graphite by chemical treatment and high-temperature expansion rolling. It overcomes the shortcomings of brittleness, loose and porous, full of elasticity, and works under high temperature, high pressure or radiation conditions, does not occur Decomposition, deformation or aging, chemical stability. It is the basic material for manufacturing various graphite seals.





C: Specific excellent characteristics:

 1. Graphite paper's ease of processing: Graphite paper can be die-cut into different sizes, shapes and thicknesses, and die-cut flat plates can be provided, with a thickness from 0.05 to 1.5m.
 2. High/low temperature resistance of graphite paper: The use temperature of graphite paper can reach 400ºC higher, and lower than -40ºC.
 3. High thermal conductivity of graphite paper: the thermal conductivity in the plane of graphite paper can reach 1500W/mK, and the thermal resistance is 40% lower than aluminum and 20% lower than copper.
 4. Flexibility of graphite paper: Graphite paper can be easily made into a laminate with metal, insulating layer or double-sided tape to increase design flexibility, and there can be adhesive on the back.
 5. Lightness and thinness of graphite paper: graphite paper is 30% lighter than aluminum of the same size and 80% lighter than copper.
 6. Ease of use of graphite paper: graphite heat sink can be smoothly attached to any flat and curved surface.






D: Application

Graphite paper is widely used in the dynamic and static sealing of machines, pipes, pumps, valves in power, petroleum, chemical, instrumentation, machinery, diamond and other industries. It is an ideal new seal to replace traditional seals such as rubber, plastics, and asbestos. material. With the acceleration of the upgrading of electronic products and the increasing heat dissipation management requirements for mini, highly integrated and high-performance electronic equipment, a new new heat dissipation technology for electronic products, namely a new graphite material heat dissipation solution, has also been introduced. This new natural graphite solution utilizes graphite paper with high heat dissipation efficiency, small footprint, and light weight. It conducts heat uniformly in both directions, eliminates "hot spots", shields heat sources and components, and improves the performance of consumer electronics products. The main application of this new flexible graphite paper application technology: used in notebook computers, flat panel displays, digital cameras, mobile phones and personal assistant devices.
