Look for better gear plastic matrial

Ericao

I have a pair gears, a worm and a column helix gear, the worm is 45# steel ,the helix gear is platic.
In life test, the helix gear had quick abrasion and plastic distortion, and then invalid.
I have used PA66+30%GF and PA46+50%GF plastic material, but no passing life test.
Except POM, please ask, do you have other better plastic materil for gear for better strength and abrasion resistance?
