EBA vs EEA
Polymer · grade comparison
EBA and EEA are both polymer grades. EEA is the stronger of the two: tensile strength 12 MPa (1.74 ksi) against 8 MPa (1.16 ksi) for EBA, about 50% more.
EEAChoose it when strength drives the design.
EBA vs EEA: 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.

EBA vs EEA — frequently asked
Is EEA stronger than EBA?
Yes. EEA has a typical tensile strength of 12 MPa (1.74 ksi) against 8 MPa (1.16 ksi) for EBA — about 50% more.
Which is cheaper, EBA or EEA?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
When should I choose EBA over EEA?
Pick EEA when strength drives the design.
