Introduction of natural graphite sheet

Product Description

Mineral processing of natural graphite sheet:

Feature Of Natural Graphite

Excellent thermal conductivity : up to 500W/m·K
Lightweight: Specific gravity : 0.87 to 1.6 g/cm3 (30% lighter than aluminum,
80% lighter than copper in the same size)
Low thermal resistance, 40% lower than aluminum, 20% lower than copper
Low heat resistance with flexible Graphite sheet
Low repulsion and easy to keep the product's shape after attaching
RoHS, REACH compliant
Siloxane Free

Application:

Flexible graphite products function as both a passive heat spreader and heat shield. These products offer a variety of in-plane thermal conductivity solutions.

The flexible graphite materials can be die-cut, or laminated with plastics and/or adhesives.

Widely used in metallurgical industry as refractories
Widely used in the electronics industry as the electrode conductive material
Water-resistant lubricating material
Anticorrosion materials in petroleum metallurgical industry
Used in a centrifugal pump and other equipment: make a pump or a seal
Used in an industrial furnace: make industrial furnace parts
The point solution process is used as an electrolytic plate: quality assurance

High temperature furnace
