Dear All I have a project to produce two injection-molded parts. One molded part was made of ABS. The other one was made of PP. These two parts contacted with each other. The ABS part rotated on the PP part (10 rpm). So, the ABS part abraded the PP part. After 500 times of rotation, the result was that the PP got serious wear. The rockwell hardness: ABS: R-Scale 110 PP : R-Scale 80 If I use an ABS material with Rockwell Hardness at R-scale 100, does the PP part get less wear? Thank you.
