Nylon 12 vs PPS
Polymer · grade comparison
Nylon 12 and PPS are both polymer grades, both high performance plastic. On the shop floor, Nylon 12 sits in a lower cost tier (premium, $$$) than PPS (specialty, $$$$$).
Nylon 12Choose it when cost is the deciding factor.
Nylon 12 vs PPS: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all polymer grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
