and display a very good surface finish (a particular benefit of the Para polymer matrix). The cycle on display was painted but Martin said no surface preparation was needed aside from degreasing. Solvay aims to develop LFT materials based on

matrix resins from across its high performance polymer portfolio, Martin said, adding that an LFT grade based on Ryton PPS is already available to customers on a pre-commercialisation basis. �

“The trick is that it is a true PEEK but we have been able to add more aromatic structure.” Brademeyer explained that a “true PEEK” polymer has a 2:1 ether-to-ketone ratio, pointing out that it is the ether component that delivers the chemical resistance. Other high-temperature polyketones, including polyetherketone (PEK) and polyetherketone ketone (PEKK) alter this ratio with an associated loss of performance, he said. KetaSpire PEEK XT polymer has a glass transition

temperature of 170°C and processes as standard PEEK but at a 20°C (36°F) higher melt temperature. The material displays a 400% higher tensile modulus and near 50% higher tensile strength at 160°C than traditional PEEK grades. It also displays a 50% improvement in dielectric strength and volume resistivity at 250°C. The new polymer is available globally in

unreinforced as well as 30% glass and 30% carbon fibre reinforced granular and powder grades. Brademeyer says price is “incrementally higher than the market price for PEEK but is far lower than PEK and PEKK.” The company also updated on its high perfor- mance LFT materials, where it sees considerable future opportunity. Global LFT Manager Eric Martin said the company had made considerable progress in integrating the LFT technology it acquired through the purchase of EPIC Polymers in 2015 with its pre-existing high performance polymers. “Since the beginning, the goal of the acquisition was to differentiate ourselves in the world of long fibre compounds and to extend in to high tem- peratures,” Martin said. “If you look to high performance applications, people are more and more trying to replace metal and most applica- tions that can be filled with short fibre have been. LFT bridges the gap.” At the show, the company displayed an electric

cycle produced by Stajvelo that uses its Xencor Para polyacrylamide LFT to produce the frame and wheels. The three parts together weigh just 9kg

Solvay Performance Polyamides introduced its Technyl Orange family of compounds for produc- tion of high voltage electrical connectors and components in electric vehicles. The products are flame retarded, resistant to high temperatures and offer very good colour retention. “In powertrain electrification systems, any live

parts carrying more than 30 V AC or 60 V DC are a potential electric shock hazard. These parts must be instantly recognisable to alert production line employees, after-sales personnel and car owners,” said Hubert Ruck, Global Director New Mobility for the company. The new materials are available coloured to RAL 2003 for Europe and RAL 2008/2011 for the US. They are halogen-free grades based on Technyl One and Technyl Star formulations and offer UL94 V-0 down to 0.4mm in some cases. Solvay is in the process of selling its Perfor-

mance Polyamides unit to BASF as part of a deal that sees Domo Chemicals acquire the European PA66 activities, including the Technyl business. �

Songwon – best known for its stabilisation and anti-oxidant products – announced a move into the fire retardants sector with the introduction of the SongFlame line of flame retardant synergists. Stating the company’s intention to become a

“driving force in flame retardants,” Songwon Board Member Dieter Morath said the new additives can considerably lift performance and improve cost effectiveness as part of phosphorous flame retardant systems. “With additions of 0.5-2.0% we can reduce the phosphorous content so the cost can be reduced and the physical and mechanical properties improved,” he said. “And if you do not want to take the economic benefit then the phosphorous system can go to higher performance levels.” The SongFlame products are said to be suitable for use with a wide range of polymers, including polyolefins, ABS and TPUs. �
