André Le Gal, Solvay, presented the company’s latest innovation in PIN flame retardant polyamides. The recently introduced halogen-free Technyl® One features best-in-class RTI values (150°C at 0.4mm) combined with excellent processing characteristics. High electrical tracking performance (CTI Current Tracking Index 600V) compared to standard brominated FR solutions is crucial to address miniaturization trend.
On top of excellent mechanical properties, Technyl® One exhibits low smoke toxicity values which are key for construction and railway applications (EN 45545-2 HL3, ISO 5659-2).
Benefits on processing efficiency were demonstrated by an internally developed corrosion test based on injection moulding.
André Le Gal notes that both the miniaturization in the E&E market (electrical and electronic) and engine downsizing in the automotive industry (in order to meet latest emission standards) have led to a steady increase of thermal constraints on plastic materials. This has fuelled innovation during the past years for polyamide producers and compounders. As a consequence, the landscape of material solutions has been moving from conventional systems to more sophisticated technical approaches addressing specific application requirements. On the other hand, the market pull by large OEM for halogen-free materials is now well established in the E&E industry. This is well in line with R&D efforts within Solvay Polyamides which are exclusively dedicated to the development of non-halogenated solutions, as integral part of the Solway Way framework and the Sustainable Portfolio Management program
