Working with TPU-Ether 95A
Is TPU-Ether easy to machine?
Machinable on rigid 55D–64D grades with very sharp, high-rake tools, high speed and low feed; soft A-grades deflect and smear — water-jet, die-cut or freeze before turning.
Can TPU-Ether be welded?
Excellent for high-frequency (dielectric), hot-plate, hot-air and ultrasonic welding as well as solvent/adhesive (polyurethane or cyanoacrylate) bonding.
Can TPU-Ether be formed, bent or molded?
Dry 2–4 h at 80–100 °C to <0.02 % moisture; injection melt 190–225 °C, mold 20–50 °C, low shear screws and generous gates; extrusion for film, tube and cable jacket with 20–30 °C rising barrel profile.
What surface finishes work on TPU-Ether?
Takes PU-based paints, in-mold film decoration, flock and pad printing after flame/plasma or primer treatment; cannot be plated conventionally, mold-texture replication is excellent.
