Thermoplastic polyurethane (TPU) for drinking water?
(OP)
I would like to know if any Thermoplastic polyurethane (TPU) is suitable for drinking water. I believe there should be many kinds of TPU, in which case it would be interesting to know if all of them don´t have problems if in contact with potable water.
Another thing would like to know if there is a time frame for the time TPU could be in contact with the water without releasing any toxic materials.

Any major reputable manufacturer should be able to supply documentation supporting which grades are approved.

e.g. one PU grade might be approved - another manufacturer's identical equivalent might not be.
As Pat suggested, you need to ask PU suppliers if they have had any approvals given for their materials for your market.

I have my production in China so I asked some people there to find out if their chinese suppliers of PU have certification, but maybe I should assume they don´t. Maybe these certifications (NSF 61 or BS 6920) are only met through big companies who make these polymers and not small suppliers.
