Waterproof films and backings
Also appears on labels as: waterproof polyurethane coating (inner layer), polyurethane coating, pu coating, tpu film
A waterproof layer the maker names: a polyurethane (PU) coating or film, TPU (thermoplastic polyurethane) or a TPE (thermoplastic elastomer) backing, coated or laminated onto the fabric.
Watched ingredients get highlighted on every product panel you open.
- Where it comes from
- Polymer plants. The film is coated or laminated onto the fabric at the mill.
- Why it's in the product
- Keeps water, mud and accidents from soaking through, or, as a tacky backing, keeps a bed or a seat cover from sliding.
- Safety and toxicity
- A film is a solid layer, not a repellent finish, so it isn't what the PFAS flag is about, and not a woven or knit fabric, so it isn't what the Synthetic fabric flag is about either. Pets do chew beds and blankets, though, and a pet that swallows pieces of one can get a gut blockage whatever it's made of (the Merck Veterinary Manual), so one that's being torn up should come out until the chewing stops.
- Interactions and who should be careful
- A waterproof layer the maker doesn't name ("waterproof layer", "waterproof liner") reads as Undisclosed material, and a vinyl (PVC) one as Soft PVC and plasticizers.
