in thermoplastics and elastomers for Calcined Neuburg Siliceous Earth
The Calcined Neuburg Siliceous Earth from HOFFMANN MINERAL, which have been launched at the last K show and for whom the company has been build up a proper facility, has had a good start into the market. The new products SILFIT Z 91, AKTIFIT VM and AKTIFIT AM, which are subjected to a downstream thermal process, perfectly fit into a multitude of new application areas because of their color neutrality and excellent technical advantages. Above all in thermoplastics the Technical Service laboratories of HOFFMANN MINERAL have arrived at excellent results with the new functional fillers, such as in polyamide, as antiblocking additives in plastic films and as extenders which are able to partially replace pigments in masterbatches and compounds.
Also in elastomers many technical benefits in new applications with the classical products SILLITIN, SILLIKOLLOID and the surface-treated AKTISIL, as well as in particular with the calcined surface-treated AKTIFIT AM are offered. When working with ethylene acrylate rubber (AEM), the fillers give evidence of imparting outstanding effects with respect to compression set and oil resistance. Very good results are also obtained with AKTISIL Q as a partial replacement of ATH while maintaining a high level of flame resistance in silicone rubber. The result is a cost reduction of the compounds.
HOFFMANN MINERAL has its stand at the K 2013 in hall 6 B51. For all new applications technical brochures have been prepared which will be presented by the marketing and sales team with pleasure.
