friction coefficient between different plastics?

friction coefficient between different plastics?

(OP)
Where can i find friction coefficients between plastics ( particularly between acetal and abs) ?

RE: friction coefficient between different plastics?

LNP gives a good lineup up friction between various plastics. See their catalog "Lubricomp." Order it on the web. LNP is now part of the GE Plastics family.

RE: friction coefficient between different plastics?

I too used the LNP literature, which I find to be an excellent resource in general.
The design for a finger wheel rotary knob went into production (moving acetal vs stationary abs) with no functional problems, though light load.  Main issues were ergonomic; that the sound of the rotary action somewhat diminished the "quality" of the part.

"The ideal client is one possessed of great good sense and perfect judgement;
that is to say, one who agrees entirely with the designer at all times and in every respect."
