POLYAMIDES | ADDITIVES
Enhancing performance in polyamides
Innovations in additives for polyamide compounds include sustainable options, flame retardant developments and a solution for warpage. Chris Saunders reports on new products
The careful selection and use of additives play a crucial role in enabling polyamides (PA) to meet diverse demands across a wide range of applica- tions including those in the automotive, electrical, industrial, and consumer industries. These addi- tives are becoming ever more sophisticated, allowing the tailoring of properties which improves performance in demanding environments and ensuring polyamides remain a versatile and indispensable class of polymers in engineering. Italy-based Greenchemicals, a specialist in
flame retardant additives, has acquired Polichem, an Italian company specialising in the supply of PA additives, including nucleating, clarifying, mould release agents, impact modifiers, PA chain extend- ers, IV enhancers for PET, dispersing molecules, and high-performance stabilisers. Through the merger, Greenchemicals will also add Polichem’s additives for improving the quality of mechanically recycled polymers to its portfolio. Greenchemicals, based in Desio, will take over operations of Polichem’s production site and lab in Garlasco,

both in the outskirts of Milan. “We consider this acquisition highly strategic,
representing a crucial synergy to consolidate our role in the formulation of plastic additives interna- tionally,” said Greenchemical’s CEO Micaela Lorenzi. “We will widen our offer in terms of customised products for styrenics, polyolefins, and engineering thermoplastic polymers, focusing more and more on sustainability.” German special wax manufacturer Voelpker’s new photovoltaic plant was recently put into operation and is making a significant contribution to reducing the use of fossil energy sources and lowering the CO2 footprint. The company offers montan wax and plant wax-based high-perfor- mance additive formulations for PA under the brand names Cevo and Cevo-R. Both Cevo 3110 and Cevo 3105 act as flow improvers and also contain stabilisers which promote a re-polymerisa- tion of partly decomposed PA. This means they can, for example, be used to upcycle agglomerate material based on milled PA fibre waste.
