For high temperature applications from -55 °C to +240 °C. Internally toothed cable ties for a secure hold on the bundle. Closed fit on the cable bundle thanks to a recess in the head. Particularly easy to loop in with excellent holding power. Small space requirement thanks to the rounded head design. Combines the performance characteristics of a metal cable tie with the simple installation of a polyamide cable tie. Easy to process by hand or with tools (process-reliable). PEEK cable ties were developed for use in extreme environments. The high-performance material PEEK means that the cable ties can be used in environments with operating temperatures of up to +240 °C. PEEK cable ties can replace various metal solutions thanks to their high temperature resistance and help to save weight in the aviation or automotive industries. PEEK cable ties have also been used for some time in rail vehicle construction and the chemical industry. The very good chemical and radiation resistance extends the area of application of PEEK to include medical technology.
