Microbial degradation of polyurethane, polyester polyurethanes and polyether polyurethanes

Applied Microbiology and Biotechnology, 1999
Polyurethane (PUR) is a polymer derived from the condensation of polyisocyanate and polyol and it is widely used as a base material in various industries. PUR, in particular, polyester PUR, is known to be vulnerable to microbial attack. Recently, environmental pollution by plastic wastes has become a serious issue and polyester PUR had attracted ...
