Fullerenes: Fighting friction - Improving mechanical properties

Connect Chemicals provides a unique access to high quality fullerenes on an industrial scale

Fullerenes are spherical shaped nano-sized carbon modifications (C60) that are used as high performance additives for thermoplastic polymers and composites.
Fullerenes are produced by pyrolysis of graphite under a helium atmosphere, giving fullerene soot as a raw material that contains up to 15% fullerenes (C60, C70, higher types).
A unique patented production and extraction process was developed that gives access to all types of Fullerenes on industrial scale and opens new possibilities for this unique nanomaterial.

Their ball-like structure (Buckyballs) gives Fullerenes unique physical and chemical properties when compared to other nanomaterials like Carbon Nano Tubes (CNT):

  • High mechanical stability C60 keeps its spherical shape under extreme high pressure (up to 20 GPa) extremely potent low-friction additive
  • Low electrical conductivity isolated molecules
  • Easy to disperse, easy to incorporate into polymers Fullerenes can react with e.g. amino-groups in Epoxy-hardeners, thus are chemically bound into the final product
  • Easy to modify giving access to tailor-made products

Applications of Fullerenes are widely known in literature and industry :

  • Modified PA6 for low-friction, high wear resistant conveyor rollers Friction coefficient is reduced by up to 50%
  • Fullerene-filled epoxy/carbon fiber composite for higher matrix/fiber binding giving tougher composite materials with increased impact strength, higher Young´s modulus and higher tensile strength
  • Fullerene-modified lubricants for high-pressure applications

Connect Chemicals is the exclusive distribution partner for these high-value, high-performance nanomaterials. With offices and partners all over the world, your local Connect Chemicals sales representative will gladly answer all your questions.
