Organic Cotton coated with polyurethane (PU).
Aesthetically PU is a lot thinner than standard oil cloth finishes, so the finished cloth does not have a high shine finish, and it drapes really well as well as being more comfortable to wear. Polyurethanes are polymers made from 2 basic raw materials; diisocyanates with a range of polyols, that undergo a reaction to form an inert substance – polythene. PU is lead, Bisphenol-A(BPA) and phthalate free, breathable, comfortable and safe for skin contact. The very thin layer of PU has been tested and found not to migrate into food or leave a “plastic” odour behind. It is a sustainable material, and all polyurethanes can be recycled.
