Products

Natural graphite is sintered with flake graphite and earthy graphite, and its carbon content reaches 99% ~ 99.8%.
Oriented film: Graphite film using advanced technology to make high-purity graphite materials to regular orientation structure

Product Description

Mineral processing of natural graphite sheet:

Feature Of Natural Graphite

Excellent thermal conductivity : up to 700W/m·K
Lightweight: Specific gravity : 0.87 to 1.6 g/cm3 (30% lighter than aluminum,
80% lighter than copperin 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.

Refractory material
Batteries
Steelmaking
Brake Lining
Foundry facings and lubricants
Pencil
Floor heating, Building thermal insulation materials
Shockproof
Other uses
