Niederzissen-headquartered compounder AKRO-PLASTIC GmbH is proud to produce aliphatic polyketone compounds, which boast outstanding mechanical properties.

Based in the Rhineland-Palatinate region of Germany, the company has found polyketone compounds are particularly well-suited to automotive thanks to their excellent wear breakage, good chemical resistance, toughness on impact loading, and extremely high abrasion resistance, making them the ideal material for drive components by Zipperle Antriebstechnik, a company based in Renningen, Germany.
The property profile of polyketone allowed Zipperle Antriebstechnik to add to their product range an additional series of highly wear-resistant gears for the machine building and precision mechanics industries. Standard and customer parts are made with extremely high accuracy in various geometries.
To complete their product portfolio, the company opted to manufacture drive components from AKROTEK PK, an aliphatic polyketone from AKRO-PLASTIC. Polyamides (PA) and polyacetal (POM) are currently the established materials for thermoplastic gears.
The addition of AKROTEK PK provides a gear material, which demonstrates advantages over PA and POM, thereby expanding the list of potential applications for various gears.
"The particularly favourable mechanical properties make this new material extremely interesting for our products. Its exceptionally high abrasion resistance and very good tribological properties make gears manufactured of polyketone suitable for significantly higher power transmissions than the gear materials typically used", said Hans Zipperle, Managing Director of Zipperle Antriebstechnik.
Cylindrical gears and bevel gears made of polyketone have meanwhile been added to the product line-up, and have already undergone extensive testing by Hans Zipperle Antriebstechnik on test rigs developed in-house. This included wear testing conducted on similar gear pairs using a bevel-gear system. The tests demonstrated that the service life of AKROTEK PK bevel gears can be extended significantly. Whereas POM and PA bevel gears show extreme signs of wear, polyketone bevel gears remained virtually wear-free following the same test period, thereby increasing the useful life of the gearboxes and decreasing downtime for repair and maintenance work.
As Hans Zipperle concluded: "Polyketone has become our go-to material for use in the gear sector and provides a superb alternative in our material profile."
