Specialty graphites for construction and HVAC applications

ECOPHIT® Expanded Graphite
Thermally conductive, non-flammable, lightweight.

The name says it all: ECOPHIT is based on natural graphite which is expanded in a refining process. This process causes the natural graphite to increase in volume making it soft and conformable. Thermal conductivity can be adjusted through mechanical compression.

The natural material graphite consists of pure carbon layers lying parallel to each other. Warmth and cold are transported along these flakes. The expansion process increases the volume of the tiny graphite flakes by a factor of between 200 and 400. As a result, the density and the weight decrease. Through compression to panels, the thermal conductivity increases. Both characteristics can be controlled in a targeted way during production – a benefit in the application with ECOPHIT.

ECOPHIT materials are not only exceptionally thermally conductive but also

  • Easy to shape and lightweight
  • Compressible
  • Completely recyclable
  • Natural and containing no binders
  • Particularly long lasting
  • Resilient against heat and corrosion
  • Non-flammable (panel)

ECOPHIT L lightweight construction panel

 
ECOPHIT L lightweight construction panel is a homogeneous, binder-free material made from expanded natural graphite. Due to its compressibility ECOPHIT L panels are suitable for incorporating a wide variety of meander tube systems, for instance. Because of the graphite’s high thermal conductivity, cooling ceilings typically fitted with such systems provide excellent heat distribution across the surface.

ECOPHIT L is easy to process and can be cut or assembled without special tooling. ECOPHIT L lightweight construction panels are available in various dimensions and densities and are supplied in sheet form.

ECOPHIT LN laminated lightweight construction panel

 
ECOPHIT LN laminated lightweight construction panels are ECOPHIT L panels reinforced on one side with a non-woven fabric making the panel more stable and easier to handle. Meander tube systems can be pressed into ECOPHIT LN easily as well. Cooling ceilings equipped with ECOPHIT LN also provide excellent heat distribution across the surface due to the graphite's high thermal conductivity.

ECOPHIT LN is easy to process and can be cut or assembled without special tooling. Additionally, surface refining by filling or painting is simply possible. Like ECOPHIT L, ECOPHIT LN laminated  lightweight construction panels are available in various dimensions and densities and are supplied in sheet form.
