Pre-dispersed polymer-bonded rubber additives Rhenogran

CNT Masterbatch for Rubber

Pre-dispersed polymer-bonded rubber additives Rhenogran

Focusing on pre-dispersed polymer-bonded rubber additives, Rhein Chemie Rheinau GmbH, Mannheim, Germany, develops reliable methods for producing CNT masterbatches for elastomers. Special emphasis is placed on gently dispersing the agglomerates of intertwined nanotubes and dispersing them uniformly in a rubber matrix.

CNTs exhibit exceptional physical properties such as high thermal and electrical conductivity as well as the enormous strength of individual nanotubes. They can be used as additives, e.g. for highly stressed safety components with antistatic properties and/or thermal conductivity.

Through use of predispersed additives, the quality of the rubber mixture can be improved considerably. Since they are dust-free, the health risk associated with inhalation of hazardous chemical dusts can be eliminated. The company produces and markets the rubber additives under the brand name Rhenogran.

Rhein Chemie has been conducting work on this new development on behalf of Inno.CNT, an initiative funded by the Ministry of Education and Research (Bundesministerium für Bildung und Forschung/BMBF) with a membership numbering about eighty industrial companies and scientific institutions, since February 2009.
