What is TangoPlus?
TangoPlus (FLX930) is a legacy transparent, flexible rubber-like PolyJet photopolymer, available on its own or as digital-material blends (FLX9840-DM through FLX9895-DM) for graded hardness. It was used for clear soft parts such as tubing and lens mockups, with default values of 1.2 MPa tensile strength and 200% elongation. Clarity is limited — parts stay slightly hazy after support removal, the surface is tacky and unpaintable, and UV exposure yellows the resin. Agilus30 Clear replaced it for new programmes. TangoPlus has a density of 1.14 g/cm³ (0.0412 lb/in³), lighter than 60% of polymer grades. TangoPlus has a tensile strength of 1 MPa (0.174 ksi), weaker than 85% of polymer grades. Elongation at break is 200% and the elastic modulus is 0 GPa (1.45×10⁻⁴ Msi).

Working with TangoPlus
Is TangoPlus easy to machine?
Do not machine — soft tacky elastomer; trim gates and flash with a sharp blade or scissors and remove support gel by waterjet plus caustic soak.
Can TangoPlus be welded?
Not weldable; join with cyanoacrylate or silicone adhesive, or print flexible and rigid regions in one job as a digital material.
Can TangoPlus be formed, bent or molded?
Printed only by PolyJet jetting at ~30–35 µm layers; keep wall thickness ≥1 mm for handling and orient tensile axis in-plane, since Z-direction interfaces are the weakest.
TangoPlus 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 |
|---|---|---|
| urethane/polyether acrylate oligomerflexible backbone giving the rubber-like network | 30 – 60 | 45 |
| photoinitiator (acylphosphine oxide typeUV cure at 365–405 nm | 0.5 – 3 | 1.5 |
| additives (stabilizer, surfactant) | 0.1 – 2 | 0.5 |
| mono/difunctional acrylate monomers (reaacrylic esters incl. isobornyl/alkoxylated acrylates | ≥ 25 (balance) |
What surface finishes work on TangoPlus?
Clear parts stay slightly hazy after support removal; a thin clear UV or acrylic conformal coat improves transparency and slows yellowing, but paint and plating do not adhere well.

TangoPlus — frequently asked
What is TangoPlus used for?
TangoPlus is typically used for transparent flexible prototypes, medical tubing mockups and soft lens simulations. In short: legacy clear flexible resin; replaced by Agilus30 Clear; highest elongation in family.
What is the tensile strength of TangoPlus?
TangoPlus has a typical tensile strength of 1 MPa (0.174 ksi) — weaker than 85% of polymer grades. Strength varies by condition: see the 7 listed tempers.
Is TangoPlus easy to machine?
Not especially — machinability is rated poor (15/100, worse than 99% of polymer grades). Do not machine — soft tacky elastomer; trim gates and flash with a sharp blade or scissors and remove support gel by waterjet plus caustic soak.
