Working with TPU-Caprolactone FR-V0

Is TPU-Caprolactone easy to machine?

Machinable only on rigid (55D+) grades with sharp, high-rake tools, high speed and low feed; soft grades smear and need freezing or water-jet/die cutting.

Can TPU-Caprolactone be welded?

Excellent HF (dielectric), ultrasonic, hot-plate and hot-air welding; solvent bonding with DMF/THF blends and polyurethane adhesives works well.

Can TPU-Caprolactone be formed, bent or molded?

Dry 2–3 h at 100–110 °C to <0.02 % moisture, inject at 190–225 °C melt / 20–50 °C mold, avoid shear-degradation and long residence times; extrudable into film, tube and profile.

What surface finishes work on TPU-Caprolactone?

Takes PU-based paints, flock and printing after corona/flame or primer treatment; can be textured directly in the mold, but polishing to a high gloss is limited by its elastomeric surface.

TPU-Caprolactone FR-V0 — frequently asked

What is TPU-Caprolactone FR-V0 used for?

TPU-Caprolactone FR-V0 is typically used for hot-melt adhesives, coatings, specialty films and cable insulation. In short: balanced ester/ether TPU; highest TPU service temperature; adhesive and coating grade.

What is the tensile strength of TPU-Caprolactone FR-V0?

TPU-Caprolactone FR-V0 has a typical tensile strength of 30 MPa (4.35 ksi) — weaker than 62% of polymer grades. Strength varies by condition: see the 7 listed tempers.

Is TPU-Caprolactone FR-V0 easy to machine?

Not especially — machinability is rated poor (30/100, worse than 87% of polymer grades). Machinable only on rigid (55D+) grades with sharp, high-rake tools, high speed and low feed; soft grades smear and need freezing or water-jet/die cutting.

Can TPU-Caprolactone FR-V0 be welded?

Yes — weldability is rated very good (75/100). Excellent HF (dielectric), ultrasonic, hot-plate and hot-air welding; solvent bonding with DMF/THF blends and polyurethane adhesives works well.

What surface finishes work on TPU-Caprolactone FR-V0?

Takes PU-based paints, flock and printing after corona/flame or primer treatment; can be textured directly in the mold, but polishing to a high gloss is limited by its elastomeric surface.

What is the maximum service temperature of TPU-Caprolactone FR-V0?

TPU-Caprolactone FR-V0 is rated for continuous use to about 85°C (185 °F), and briefly to 120°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
