Sintered metallic nonwovens and heatable nonwovens from Norafin

Norafin Industries (Germany) GmbH presents at Techtextil two new products: heatable, flexible nonwovens with good resin absorption capacity especially for panel heater components, composites and electrodes and new sintered nonwovens with a high content of metal particles or fibres for multiple applications as materials resistant against high temperatures and chemicals.

Heatable Nonwovens

Together with project partners from the industrial and university sector, Norafin Industries (Germany) GmbH has developed a range of electrically heatable, flexible nonwovens with good resin absorption capacity especially for panel heater components, composites and electrodes. The innovative, energy-efficient, functional heatable nonwovens distinguish themselves through minimal heating-up times in the low voltage range (U < 48V), minimal bulk, ease of use, good drapability, and homogeneous heat distribution and output during the heating-up and cooling-down phases. Numerous new opportunities present themselves for the use of heatable nonwovens, in particular with GRPs. The results can be transferred to a number of different, yet similar areas of application, including mobile, non-rigid areas (i.e. heatable clothing, automotive heating, etc.) or stationary, rigid areas (i.e. heaters in the medical or wellness sector, bathtubs, lawn heaters, panel heaters in greenhouses, and many more).

Sintered metallic nonwovens

In the scope of a joint R&D project called the “Development of an innovative technology for the production of highly filled, functionalised, porous sintered papers and nonwovens, partial project: – Sintered metallic nonwovens”- a completely new technological approach (filled, semi-finished products) with a high content of metal particles or fibres has been followed, using highly efficient nonwoven production technologies. New, flat semi-finished products (sintered nonwovens), filled with metal powders or metal fibres, have been developed which can be further processed e. g. to sleeves or fold structures, or thermally debindered and sintered to porous or highly porous metallic materials. The main target of the joint project is, among other things, the development of highly filled nonwovens with a metal powder or metal fibre content of approx. 70 – 90 % by weight, corresponding to the respective application-related requirements for the production of sintered materials. They can also be applied as metal-loaded materials (green bodies) directly, or after thermal sintering, as semi-finished products for multiple applications as materials resistant against high temperatures and chemicals (e. g. filter agents for liquids and gases, heat exchangers, porous burners, catalysers etc.).
