Squeaking and crunching plastics

[wonderer]

Are there any useful guidelines how to decrease squeaking between plastics (same or different)? Are there plastics that are particularly bad in this matter? Easy ways to get roung this problem? I am interested in styrenics, arcylics, PC and polyamides.

Use dissimilar plastics if possible. You can use lubricated or "anti-squeak" grades from suppliers like LNP.

Car companies have spent millions researching squeek and rattle. Pick an already done example of matting plastics that is similar to your application and study it.
As plasticbob says try dissimilar materials .... also try different fixing systems and damping systems.
