High flow PA6,6 targets auto parts

Rhodia introduced a new Technyl Star AFX PA6,6 grade characterised by improved flow characteristics, enabling it to be injection moulded with as much as 60% glass fibre reinforcement.

The company says the resin bridges the gap between conventional PA6,6 and high performance polyamides, such as polypthtalamide and polyarylamide.

Laurent Schmitt, president of Rhodia Polyamide said the AFX material is a “game-changing” resin.

“The price is between conventional PA6,6 and PPA, but closer to PA6,6. We have sampled it and it has been tested at customers, with parts moulded and under tests. It is available to customers now,” he said.

The company also introduced Technyl HP at the show, a high temperature resistant PA 6,6 grade targeted at under-hood applications that are presently produced in PA6 but lack the ability to handle the increasing temperatures in this application area. Unlike PA6 and standard PA6,6, Technyl HP can withstand exposure to 1,000 hrs at 200°C and shows less cracks than these materials after 200 hrs. It is claimed to deliver PA6,6 processability at a PA6,6 cost level.

Schmitt said at the show: “We want to be the nylon champion – the PA6,6 champion. While the market is growing at 5%, we are growing twice as fast, at 11%”.
