Dry PPA vs. PPS

Both dry PPA and PPS are thermoplastics. There are 10 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown.

For each property being compared, the top bar is dry PPA and the bottom bar is PPS.

Dry PPA Polyphenylene Sulfide (PPS)
