Polymer Compatability-Buzz Squeek Rattle
(OP)
Are there any potential "itch" or squeek issues with using a 20% GF Nylon substrate with a soft PVC overmold?
How about a 20% GFNylon against an Olefin?
Any feedback or direction to additional resoures would be appreciated.
Best Regards,

What you ask is an interesting question. I don't know of one. As the effect relies on surface friction, it would be very sensitive to additives including antioxidants, UV stabilizers, slip aids, anti-blocks etc.. That means that you can't predict what a polymer pair will do because it's more about the additives than the polymers themselves.
When I worked at BASF they claimed that their ABS/PA blend never squeaked and that was a selling point (commercial name Terblend N). I always wondered why that would be.

It can be important on interior trim and dashboard components on cars.
BASFs opposition unkindly refereed to that range as Terdblend

Mechanically, it's a lot like ABS/PC.
