However, the production of these high-performance fibres is complex and requires specialized processing aids. This is precisely where the new development from the internationally active chemical company Zschimmer & Schwarz comes in.

Zschimmer & Schwarz, a globally recognized manufacturer of spinning preparations, has developed a silicone-based preparation for intermediate modulus carbon fibres (up to 7 GPa). This innovative solution is applied directly to the precursor and optimizes the production process by improving adhesion and stability. For the yarn, this means fewer filament breaks and better yarn closure. The spinning preparation was developed together with a well-known partner in the carbon fiber industry.

When developing new formulations, Zschimmer & Schwarz can rely on the in-house production of customized emulsifiers. These products are in great demand from their customers, for example in cosmetics and personal care products, cleaning agents and detergents and many other areas. The company’s emulsifiers guarantee a homogeneous distribution of particle sizes, as confirmed by analyses. The narrow particle size distribution promotes uniform application to the carbon fiber precursor, which in turn increases the quality of the end products. The Zschimmer & Schwarz development department can make individual adaptations to specific requirements for its customers, which underlines the flexibility of the solution.

This innovation expands Zschimmer & Schwarz’s already broad portfolio of silicone formulations. This includes established products for fibers as pillow filling (Zetesoft FF 100), for textiles to improve the soft handle (Cefasoft MSR) and many other process auxiliaries such as defoamers (Contripon S). This underlines Zschimmer & Schwarz’s expertise in the development of advanced chemical solutions.
