Lehmann & Voss has devel- oped the Luvocom Detectables magnetic compound range for manufacturers of components
used in the food processing machinery sector. The compounds, which are
suitable for injection moulding applications, provide weight and cost saving opportunities compared to currently available magnetic polymers, which typically require a secondary post-moulding magnetising step, according to the company. Lehmann & Voss claims
that by combining soft magnetic components with impact resistant polymers it has been able to manufacture a range of compounds that are

❙ The F-4 and F-4D fluoro- polymer grades from Russia’s HaloPolymer have been certified compliant with the enhanced European Directive 10/2011, which details requirements for polymers intended to contact food. The tests were carried out by SGS Multilab in France and included specific and total migration under the most severe conditions.

Saint-Gobain targets thermal conductivity
reliably detected by the current technologies uses in the food processing industry, including metal and x-ray systems. The company says the new materials mean manufacturers can safely replace costly and expensive stainless steel. The Luvocom Detectable
grades are supplied ready to process. Moulded parts are said to display a good surface finish and the materials can be coloured to comply with food type identification. ❙

Teknor Apex launches recycled PAs
Teknor Apex has launched a range of custom-formulat- ed polyamide compounds which contain a proportion of recycled material. The Recyclon grades can be specified with a wide range of recyclate loadings. The grades are designed to deliver cost savings and meet end user require- ments for ‘green’ materials. Target applications include automotive components where recycled content is mandated, as well as consumer and industrial items where cost reduction is a key consid- eration. A Recyclon compound is already being used in a lawn furniture application. “Not every nylon
Saint-Gobain has introduced CarboTherm hexagonal boron nitride (hBN) products for adding thermal conductivity to thermoplastic compounds while retaining electrical insulation. The company, which is a
leading producer of boron nitride for a wide range of applications, says hBN grades provide low density and a low coefficient of friction and are available in large crystal sizes

to achieve maximum thermal conductivity. Four different grades are
offered: PCTF5, PCTP16, PCTP30 and PCTP30D. Target applications include: custom-moulded heat sinks for circuit boards; enclosures for LED bulbs; telecommuni- cation device components; and automotive under-the- hood and electronic compo- nents. ❙

application calls for the full portfolio of elevated properties provided by standard compounds,” says Scott Fleming, vice president in charge of the company’s Nylon Division. “The Recyclon product range provides a new option for balancing cost and value, and as a custom compounder Teknor Apex is well positioned to help each customer strike the balance that precisely meets their needs.” One of the main sources
of raw material for produc- ing Recyclon compounds is recycled post-consumer carpet fibre based on PA 6 or PA 66. ❙
