Giuseppino Fortunato

we used THF (boiling point 66°C), or mixtures of THF/DMF.

Pino

Abdelkader BOUAZIZ

Dear all,

acetone (56°C) and alcohols (low boiling) are good solvants for TPU. Regards

Omprakash Pammi Munuswamy

Hi,

Combination of ACETONE/MEK is working well for TPU.

Kevin Bethke

THF works quite well.

Thomas Sørensen

Ethylacetate is very effective, but isobuthylacetat works as well.

cyclohexanone

Mohammad Balfaki

actually, start by some of them sepratebally I suggest to start DMF and CHLOROFORM

Nadir Fadhil Habubi

I think THF with suitable temperature will be the best solvent

Hashem Tabebordbar

Acetone is good

Tekin Özdemir

DMF and THF are the best, but bring about some health hazards.

Lidia Verano Naranjo

In my experience, DMSO y a quite solvent for TPU, but its boliling point is similar to DMF. Acetone and alcohols maybe solve TPU but the process happens very slow.

I think NMP is the best.
