Typical TPU
- Strong abrasion and tear for handles and wear pads
- Higher durometer range for structural elastomer segments
- Can need longer cycle than very soft TPE
Elastomer comparison
TPU vs TPE: Elasticity, Grip, and Overmold Compatibility
TPU brings abrasion and oil resistance. TPE grades span soft touch to economical grips with easier processing on some substrates.
Elastomer comparison
Soft touch is not one resin
Overmold programs fail on bond and tear, not on color alone.
Match the elastomer to the rigid substrate and the chemical environment.
NetProto overmolds onto approved rigid grades when DFM confirms bond windows.
Resin choice
Typical versus Typical at a glance
Use this routing before you lock the BOM. NetProto molds both once the resin is specified on the quote.
Typical TPE
- Wide durometer range for soft touch
- Some grades bond easily to PP and ABS substrates
- Lower cost for consumer grip surfaces with mild service
Decision table
Where each resin usually wins
Qualitative tradeoffs for molded parts. Confirm shrink, fill, and tooling details on the material guide.
| Factor | TPU | TPE |
|---|---|---|
| Abrasion | Excellent | Grade dependent |
| Oil exposure | Often better in TPU | Check grade datasheet |
| Bond to PP | Requires compatible TPU grade | Many TPE grades optimized for PP |
| Feel | Can feel rubbery or matte | Very soft touch possible |

Common questions
Is TPE always cheaper?
Often on soft consumer grips, but specialty TPUs win when oil or abrasion tests apply.
