A typical area of application for paste extrusion compounds is the production of tubing for Bowden gears - so-called push-pull cables, which are typically used in the automotive industry. The polyethylene tubing used up to now are being increasingly replaced by those made of PTFE because of the higher temperatures encountered.
In the past PTFE tubing was normally reinforced with PPS for enhanced abrasion resistance. It was found that the abrasion resistance of the push-pull cables was drastically increased by Ceramer, compared to PPS. This results in safer, more reliable operation, even with insufficient or no lubrication. The push-pull cable will not be rubbed through. Even the total absence of a lubricant will not cause the push-pull cable to rub through, in contrast to PPS.
