Nevertheless, particular attention must be paid to the friction pairs. Compounds have been specially developed for plastic components made of ABS, PC+ABS, PC+ASA and PA-blends that provide tribological advantages when paired against PA com-pounds with mineral or glass reinforcement. These compounds have another advantage over material solutions containing PTFE that have a lower surface quality and which undergo greater wear in continuous operation tests: they are characterised by very good abrasion resistance and do not require an additional coating.
Pictures 1 and 2 (see attached) show the results of a friction pairing between PA66 GF30 and a PC/ASA compounds from ROMIRA ROMILOY® 6020/04 (tribological functionalized) compared to ROMILOY® 6020 (standard grade). The reduced friction resistance between the functional partners is clearly evident.
The most recent anti-squeak studies of various new formula-tions of PA66 GF30 based on a stick-slip test gave a risk priority number of between 1 and 2, which indicates a very low squeak risk under room temperature conditions. ROMIRA's development work is currently focusing on seating applications in vehicles with mounted and built-in parts that are in contact with synthetic leather.
