ABS Grades with Low Friction

Reducing Undesirable Noises

Elix Polymers, Tarragona, Spain, has developed a range of specialty grades of ABS and PC/ABS to reduce the squeak that is generated by the contact of plastic parts with other plastic parts, leather, PVC-foil or other products. These undesirable noises can negatively affect the driver´s comfort and the quality impression of a car.

The newly developed low-friction grades are especially suitable for automotive interior parts like door handles, seating parts, cup holders, and air vents, but also for other automotive applications (© Elix Polymers)

The new grades were submitted to stick-slip tests at several premium Automotive OEMs according to VDA230-206 at testing machines from Ziegler Instruments with very positive test results: a 10 point scale is used where 10 is the highest risk level. The newly developed Elix grades managed to score 1 – the lowest risk level. Tests were conducted with different forces (10N, 40N) and speeds (1mm/s and 4mm/s) at several temperatures.

The new grades use Elix Polymers base polymers: standard ABS, high heat ABS, ABS/PC or PC/ABS - and because their key properties remain the same, this does not affect existing OEM approvals of ELIX grades. Furthermore, as the shrinkage of the materials stays the same, current molds can be used without further need for modifications.

According to Fabian Herter, Industry Manager Automotive at Elix Polymers, with these new grades, significant cost savings are possible: “Until now, in many instances, fabrics or grease had to be added afterwards to reduce squeak and rattle. However, this involves additional costs and manual labor – and therefore is not ideal. Now, thanks to these new ElixX grades, we are able to offer a more competitive solution when compared to other resins that are currently available.”
