Conductive materials for a very wide range of applications
Conductive breaks into new industries
The conductive systems from BÜFA Composite Systems address a range of challenges commonly faced by a wide variety of industries. BÜFA®-Conductive Line products offer completely new possibilities for applications requiring low electrical resistance. The safety of people and technology is paramount in all conductive applications. Objects and equipment as well as liquids must not be dangerously charged in areas where there is a risk of explosion. In explosive areas, only conductive objects and equipment may be used.
The BÜFA problem solver: Conductive products
SWCNTs (single-wall carbon nanotubes) act like sub-microscopic strands of wire in the reaction resin’s matrix. At specific (low) concentrations and above, they form a network of fine molecular “wires” that run through the material. This is how gelcoats enhanced with SWCNTs get their excellent electrical conductivity.
The surface resistances of the new BÜFA products are set to constant values <109Ω. Individual gelcoats of the Conductive series are optimised for a surface resistance <106Ω. The requirements and also test methods for proving the resistance can vary greatly. Take advantage of the technical support.
Several applications utilising BÜFA®-Conductive Line products have been successfully tested in practice for a long time.
Unsaturated reactive resins are still the material of choice when it comes to the manufacture of premium and aesthetically pleasing GRP parts, for example those used in making cars, boats, rail and commercial vehicles, tanks, pipes, swimming pools and sanitary facilities.

Safety, fire & explosion protection
New are shades of colour not possible before, all the way to translucent gelcoat formulations, can now be formulated. These new formulations cannot be distinguished visually from regular, non-conductive materials. Due to the small quantities of single-wall CNTs required, high gloss components can be produced.
Processing properties remain the same which allows normal processing equipment to be used. Viscosity values also remain at normal levels . This guarantees clearly better de-airing compared to conventional materials. Because of the lower, reduced quantity of pigments used, curing behaviour is no longer negatively influenced.
High Process Reliability
Conductivity values can be repeatedly achieved from one component to the next. The fine distribution of the nanotubes in the gelcoat guarantee consistently uniform conductivity values.
