The power of E&E materials on display at Fakuma 2018


Electrical and electronic applications are an increasingly important development area for plastics materials manufacturers. That trend will continue well into the future, as road vehicles move from petrol to electricity as a power source, as domestic appliances get smarter, and as LEDs take over from incandescent lighting. Here’s a look at some of the latest progress being made, much of it to be on display at the Fakuma show in Frie- drichshafen, Germany, this month. At polyamide 66 major Ascend Performance


Materials, its Global Segment Leader for E&E, Ed Nerlich, says considerable resources are going into expanding the Vydyne portfolio of PA66 grades for connectors, working together with connector producers and OEMs to develop improved solutions, especially in terms of safety. Many applications, most notably unattended

appliances, require finished parts to pass the Glow Wire End Product Test (GWEPT) at 750°C. “We set out to enable our customers to exceed that,” says Nerlich. “Vydyne FR350J [an unreinforced flame- retardant type launched at Fakuma 2017] enables parts to achieve a GWEPT rating of over 775°C – and sometimes even 800°C – with no flame.” Nerlich also highlights Vydyne ECO366H, which is a non-halogenated unfilled FR PA66, which he says responds to the trend for thin-walling in connectors with improved electrical performance. This grade achieves a UL94 V-0 rating at 0.2mm and also has an RTI electrical rating of 150°C. “This, together with a tracking index (CTI) of over 600V, makes it unique among unreinforced PA66 types,” says Nerlich’s colleague Development Engineer Ralph Guyer. Vydyne ECO366H is also being considered for terminal blocks.
