Technora vs UHMWPE Fiber (Dyneema/Spectra)
Composite · grade comparison
Technora and UHMWPE Fiber (Dyneema/Spectra) are both composite grades. Technora is the more ductile: elongation 4.4% versus 3.8% for UHMWPE Fiber (Dyneema/Spectra). UHMWPE Fiber (Dyneema/Spectra) is lighter (0.98 g/cm³ vs 1.39 g/cm³ for Technora) and UHMWPE Fiber (Dyneema/Spectra) is stiffer (109 GPa vs 72 GPa).

UHMWPE Fiber (Dyneema/Spectra)Choose it when weight is the constraint.
Technora vs UHMWPE Fiber (Dyneema/Spectra): propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all composite 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.

Technora vs UHMWPE Fiber (Dyneema/Spectra) — frequently asked
What is the difference between Technora and UHMWPE Fiber (Dyneema/Spectra)?
Technora and UHMWPE Fiber (Dyneema/Spectra) are both composite grades. Technora is the more ductile: elongation 4.4% versus 3.8% for UHMWPE Fiber (Dyneema/Spectra). UHMWPE Fiber (Dyneema/Spectra) is lighter (0.98 g/cm³ vs 1.39 g/cm³ for Technora) and UHMWPE Fiber (Dyneema/Spectra) is stiffer (109 GPa vs 72 GPa).
Which is cheaper, Technora or UHMWPE Fiber (Dyneema/Spectra)?
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.
Which is easier to machine, Technora or UHMWPE Fiber (Dyneema/Spectra)?
UHMWPE Fiber (Dyneema/Spectra), by a small margin. Both rate poor for machinability — 25/100 against 20/100 for Technora.
