What is Technora SHORT-CUT?
Technora SHORT-CUT is Technora in the SHORT-CUT grade — use as reinforcement/anti-squeal additive in friction materials, gaskets, sealants, cement and thermoplastic compounds. Technora SHORT-CUT has a tensile strength of 3,000 MPa (435 ksi), stronger than 81% of composite grades. Elongation at break is 4.4% and the elastic modulus is 70 GPa (10.2 Msi). Technora SHORT-CUT has a density of 1.39 g/cm³ (0.0502 lb/in³), lighter than 66% of composite grades. Its glass-transition temperature is 300°C (572 °F). T200 is the default condition FabDigit quotes; SHORT-CUT is available on request or by drawing note.
Advantages
- Ductile — tolerates forming and impact — 4.4%, better than 84% of composite grades
Limitations
- Absorbs moisture — dry before molding — 2%, worse than 88% of composite grades
- Poor heat conductor — 0.05 W/m·K (0.0289 BTU/hr·ft·°F), worse than 87% of composite grades
- Degrades in UV without stabilisers — 25/100, worse than 86% of composite grades

Working with Technora SHORT-CUT
Is Technora easy to machine?
Cutting fuzzes badly — use hot knife, ultrasonic or laser for fabric, and PCD/serrated or compression-router tooling with sharp positive rake for cured laminates; expect no melting, only charring.
Can Technora be welded?
Not weldable or fusible (decomposes ~500 °C without melting); join by stitching, splicing, mechanical termination or adhesive/resin bonding.
Can Technora be formed, bent or molded?
Processed as yarn, cord, woven/UD fabric or short-cut fiber into thermoset (epoxy, phenolic, vinyl ester) or rubber matrices; low compression strength means avoid fiber-direction compressive loading and consider hybridizing with carbon or glass.
What surface finishes work on Technora?
Use RFL/epoxy dip or adhesive-activated grade (T221/T240) for rubber and resin adhesion; protect from sunlight with pigmented jackets, coatings or overbraids because UV strength loss is rapid.
Technora chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| terephthaloyl chloride (terephthalamide mol % of monomer feed; acid chloride component | 48 – 52 | 50 |
| p-phenylenediamine (PPD)mol %; rigid para unit | 20 – 30 | 25 |
| 3,4'-diaminodiphenyl ether (3,4'-ODA)mol %; co-monomer giving the copolymer its higher elongation and hydrolysis resistance | 20 – 30 | 25 |
| finish / spin oilsurface finish on filament yarn (wt %) | 0.2 – 1.5 | 0.5 |
Technora SHORT-CUT — frequently asked
What is Technora SHORT-CUT used for?
Technora SHORT-CUT is typically used for submarine cables, optical fiber cable strength members, tire cords and ropes. In short: highest-elongation para-aramid; best aramid fatigue resistance; adhesive-activated yarn grades.
What is the tensile strength of Technora SHORT-CUT?
Technora SHORT-CUT has a typical tensile strength of 3,000 MPa (435 ksi) — stronger than 81% of composite grades. Strength varies by condition: see the 4 listed tempers.
Is Technora SHORT-CUT easy to machine?
