Key features & benefits

Strength you can build on

The reactive polyurethane network forms as it absorbs ambient moisture — higher long‑term strength, dimensional stability and low creep than conventional hot melts, yet flexible for vibration and thermal cycling.

  • Moisture‑cured chemistry — high final strength after crosslinking.
  • Fast green strength — quick handling, high line speed.
  • Heat & chemical resistance — stable across a wide range.
  • Low emissions — wets PVC, aluminum, wood, ABS, PET foils.

PUR advantage

Reactive, not just hot

PUR forms a crosslinked network with higher heat, chemical and creep resistance than thermoplastic EVA — and stays flexible for thermal cycling after cure.

FAQ

Common questions

PUR vs EVA hot melt?
PUR is reactive, moisture‑cured, crosslinked — higher heat, chemical and creep resistance. EVA is thermoplastic, easier to rework, lower final performance.
How to choose a grade?
Match viscosity to method (slot‑die/roller/nozzle); pick open time for line speed and assembly complexity; target final properties for the end‑use.
Low‑energy plastics or metals?
Yes, with surface prep and primers where needed; dedicated PVC/aluminum grades improve wetting and long‑term adhesion.
Packaging available?
Moisture‑protected cartridges, pails and drums preserve reactivity and shelf life.
Production line too?
Yes — turnkey reactive‑hot‑melt lines with SS reactors, mixing/heating, vacuum degassing and moisture‑controlled transfer.
