K. D. Feddersen introduces the new materials ASCEND HiDura� ThermaPlus and POKETONE�

Ascend Performance Materials has developed a new range of unreinforced PA 6.6 that is designed to increase long-term thermal stability to 150 °C and even higher temperatures. This is achieved without compromising the material's ductility, processability or mechanical strength.

Picture 1: One possible area of application for HiDura™ ThermaPlus is cable ties.

The material exhibits remarkable flowability, allowing it to be processed under conditions similar to standard injection moulding of PA 6.6 and producing parts with properties that rival those of PA 4.6. Because of its processing characteristics, it can serve as a direct, trouble-free replacement for PA 4.6 without requiring mould modifications. The material also has a slightly lower density, resulting in a weight savings of about 3 %.

HiDura™ ThermaPlus is ideal for applications like protective housings for high-temperature sensors, cable ties, fasteners and in high temperature hose clamps for the automotive industry.

POKETONE™

We supply the original polyketone (PK) from Hyosung Chemical for injection moulding. This combines the positive properties of many engineering plastics and, thanks to its approvals for drinking water and food contact, offers you an alternative for a wide range of application segments.

We are looking forward to supporting your polyketone project needs – including technical services and tailor-made logistics concepts.
