Radici Group’s High Performance Polymers business launched Radilon Nextreme, a new line of easy-to-process performance polyamides capable of long term operation in air up to 230°C. Three grades are available. Radilon NeXTreme RV350HHR 3800 BK is a 35% glass reinforced product and RV500HHR 3800 BK is 50% glass reinforced. Both are intended for injection moulding. The third grade – HSW 100 NT – is intended for technical fila- ment production. The two moulding grades are primarily aimed at automotive applications such as air intake compo- nents. Radici said they offer better chemical resistance and lower absorption than PA66 alternatives. The ability to process the grades in water-cooled moulds is a benefit over PPA, according to the company. Nicolangelo Peduto, Global R&D and Product
Innovation Manager at Radici High Performance Polymers, said the new grades are a combination of polymerisation and compounding enhancements and take advantage of the company’s in-house polymerisation capability. “Acting on the polymer chain is a key way to enhance the polymers for applications that are more and more aggressive,” he said. Radici said the company would be adding more
grades to the Nextrem portfolio, with the electronics industry a key target market. Potential opportunities include the substitution of thermosets in high temperature applications such as lead-free soldering. �

Sibur said that its 2m tonne/yr capacity ZapSib PP facility at Neftekhim in Russia is now producing test volumes and is on track to near triple its polyolefin capacity to 3.24m tonnes of PE and PP polymer by 2020. That, however, could be further expanded to reach 5.5m tonnes by 2024 if it goes ahead with a proposed joint venture with Gazprom that would include up to 2.7m tonnes of new PE and PP
capacity at Svobodny. A decision on whether to go ahead with that investment, which would make Sibur the largest PE and PP producer in Europe, will be taken in the next few months, the company said. �

SI Group presented its Ultranox LC platform of antioxidants, which are designed to improve colour control in processing of polyolefins, as well as previewing a new solid antioxidant system. According to New Business Development Manager Ron Becker, the bigger and faster extrusion systems being used today place a much greater thermal loading on the resin and stabilisa- tion package. This can result in perceptible yellowing (he said the average person can detect a difference of 1-2 yellow index units). Ultranox LC is based on an already-approved food additive so the company is confident it will successfully achieve FDA and EU food contact approval. It acts as a non-conventional antacid and is said to outperform the company’s long established Ultranox 626 in all respects except melt flow control. Three LC grades will be available initially:
LCPP301 is a fully formulated stabiliser package; LCPP501 is intended for fibre production; and LCPP701 is formulated for production of stearate- free BOPP films. The company also previewed what it described
as a “next generation solid antioxidant” to replace AO1010, AO-168 and phenolics. It claims its new system offers comparable economics with better colour stability at a lower loading level (down from 1,500ppm to 1,170ppm).
Global Business Development Director Polymer Additives Martin Pavlik said the new additive could benefit polymer producers looking to make their PE and PP products more recyclable without adding more extractable content. He said the company hopes to bring first grades to the market within three years. �

Solvay introduced KetaSpire PEEK XT, a new high performance polymer claimed to offer the chemical resistance of traditional PEEK grades together with a 20°C improvement in Tg and 45°C increase in melt temperature, supporting high temperature applications requiring high strength and stiffness. “We were able to boost thermal and mechanical performance while maintaining PEEK’s ether-to- ketone ratio, which accounts for the polymer’s superior chemical resistance,” said Doug Brade- meyer, Ultra-Polymers Business Manager for Solvay’s Specialty Polymers global business unit.
