Polyurethane - Chemical Resistance
Chemical resistance of Polyurethane (PUR).
Polyurethane (PUR or PU) is a polymer composed of organic units joined by carbamate or urethane links.
Note that polyurethane is not a uniform class of material. The chemical resistances listed below should always be checked with manufacturing data.
