Carbon Thermal Conduction Expandable Graphite Powder For PU

Expandable Graphite

Expandable graphite is a synthesized intercalation compound of graphite that expands or exfoliates when heated. Once heated, it results an increase in the volume of up to 400 times, a lowering of bulk density, and approximately a 10-fold increase in surface area. Then it’s compressed into a highly cohesive flexible sheet.

Another principal application is as a flame retardant. As a result of the heat of a fire the graphite expands and creates an intumescent layer on the surface of the material. This retards the spread of fire and minimizes one of the most harmful effects of combustion: the creation of toxic gases and fumes.

Benefits of expandable graphite as flame retardant:
1. Forms an intumescence layer with Thermal Radiation Shielding, with superior Heat Diffusion.
2. Stops or slows the spread of fire and toxic gases.
3. Easy to apply, cost Effective, satisfied performance with low adding levels.
4. Non-toxic, non-halogenated fire-stop additive.
5. Neutral surface pH makes compatible with any catalyst system.

Company introduction:

Since 1985, Hensen Graphite has been proudly serving customers around the globe.

With years of development, Hensen has invested and established three operation factories, and a number of associated partners. By doing so, Hensen becomes a professional and reliable carbon & graphite producer and supplier.

As the built of Inner Mongolia Hensen New Energy Technology Co., Ltd.in 2018, which produced 100,000pta GPC per year, Hensen became the outstanding enterprise that stretches over natural and synthetic graphite industry.

While focusing on meeting our customers’ needs, we continue to maintain our position as the supplier of choice not only natural graphite but also synthetic materials. Hensen supplies more than 180, 000TPA various kinds of carbon materials to a wide range of industrial applications, including fire retardants, friction materials, batteries, fuel cells, lubricants, cast metals, drilling, paints, coatings, and plastics.

We opened its eyes from the day of foundation, and keep occupational safety, quality assurance, sustainability in minds all the time.
