Right: Radici Group’s Radilon Mixloy compounds use PA blending technology to meet
demanding performance requirements
Compound development Compounders and resin manufacturers are developing new PA compound formulations that meet higher performance, processing and sustain- ability requirement through the use of additives and innovative filler/reinforcement combinations. Ascend Performance Materials has launched several new grades of its HiDura long-chain PA 6/10 and 6/12 polymers, which are designed to provide good dimensional stability and long life along with enhanced resistance to chemicals, impact and abrasion. The new grades are said to be suitable for use in automotive fuel system and brake line applications, cable ties for solar power systems, battery seals and monofilaments for brush bristles. The Durethan ECO PA product line from
Lanxess uses reinforcing fibres produced from waste glass. Durethan ECOBKV30H2.0, ECOB- KV35H2.0 and ECOBKV60XF are the most recent examples, using 30, 35 and 60% by weight recycled glass fibres respectively (the glass comes from waste left over from glass fibre production). Independent verification company Ecocycle has applied mass balance methods to the process and awarded an ecoloop certificate in accordance with ISO 14021:2016. Lanxess says the primary
target for the new compounds is the automotive industry.
“For instance, Durethan ECOBKV60XF offers excep- tional strength and rigidity, which makes it suitable for manufacturing structural components such as front
ends, pedal bearing brackets and A, B and

bolster for the latest Ford Kuga, could be produced in Durethan ECO PA compounds
C-pillars, as well as lightweight battery trays for electric vehicles,” says Dr Guenter Margraf, Global Product Manager. The company says its High Performance Materi- als unit will gradually increase the number of ECO product types certified in accordance with the mass balance method. It plans, for example, to launch a new PA6 with a glass fibre content of 30% and a reduced carbon footprint due to changes in its caprolactam production process.
Blending solutions The High Performance Polymers division of Italy’s Radici Group has introduced Radilon Mixloy, a new range of PA blends for automotive, consumer goods and E&E applications produced using compatibilisation technology. “At the moment, development is focused on certain types of alloys.

But, in the future, we plan to add other products, with the goal of achieving properties that are simply not attainable with individual polymers,” says Nicolangelo Peduto, Research and Develop- ment Manager. “One of our objectives is to be able to meet the demand coming from market niches. Furthermore, thanks to our upstream vertically integrated polyamide production, we have at our disposal a number of different types of polymers that give us design freedom in formulating the new Radilon Mixloys,” he says. The base materials for the Radilon Mixloy
product offering developed so far are PA6, PA66 and long-chain PAs, some of which are made from bio-sourced materials. The products offer high- performance, including good thermal resistance, mechanical resistance and surface appearance. They also offer low density, dimensional stability and ease of processing, together with low water absorption, improved tribological properties and low permeability. The company sees many fields of application for
the Radilon Mixloy products. In the automotive sector, they are suitable for interior parts, as well as for exterior body and engine compartment parts. Outside of automotive, the company sees the new blends finding applications in sporting goods, household appliances, and electronic equipment housings. They can also be used for FDM 3D printing due to their ease of processing, low water absorption and minimal shrinkage.
