Polyurethane and TPU
Not a fluorochemicalBase materials. Also written polyurethane, PU, TPU, PUL.
A flexible polymer used as a film, a laminate, a coating and a foam. The waterproof layer in a lot of bags, pads and leak proof linings.
Polyurethane is the main fluorine-free route to a waterproof layer, so finding it named is usually the answer a reader wanted rather than a new question.
What the makers actually said
Of the 132 graded products whose materials record polyurethane alongside a coating or finish, 100% name no coating chemistry anywhere in their published materials. This is a count of what companies published. It is not a statement about what any product contains.
- Named a fluoropolymer
- 0
- Named a coating that is not a fluorochemical
- 0
- Named no chemistry at all
- 132
A further 167 products record polyurethane with no coating or finish at all, so there is nothing for a maker to have disclosed. They are outside the split above.

How those 299 products graded on our rubric
These are model-based estimates, not laboratory tests, scored on one public rubric. Read the spread against the categories underneath it rather than as a verdict on polyurethane in the abstract, because the rubric gives every category a baseline and a term concentrated in one category will carry that category’s spread with it.
Median grade 65 out of 100, across 27 categories.
| Grade | Products | Share |
|---|---|---|
| Excellent | 143 | 47.8% |
| Good | 28 | 9.4% |
| Poor | 115 | 38.5% |
| Bad | 13 | 4.3% |

Edition 2026-10-08, read from 11,337 graded products carrying a material string, and frozen at that date. A term is matched against the material and construction string recorded for each product, written from its published materials, specification and ingredient list rather than from a laboratory test. Products count under every term they match, so the totals across terms overlap. Found something wrong? Tell us.
