DAIP vs DAP
Polymer · grade comparison
DAIP and DAP are both polymer grades. DAIP runs hotter in service (205°C vs 180°C continuous) and DAP conducts heat better (0.5 W/m·K vs 0.42 W/m·K).
DAIPChoose it when the part sees heat.
DAIP vs DAP: 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.

DAIP vs DAP — frequently asked
What is the difference between DAIP and DAP?
DAIP and DAP are both polymer grades. DAIP runs hotter in service (205°C vs 180°C continuous) and DAP conducts heat better (0.5 W/m·K vs 0.42 W/m·K).
Which is cheaper, DAIP or DAP?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
When should I choose DAIP over DAP?
Pick DAIP when the part sees heat.
