WebPolyurethane (PUR) is produced by diisocyanate polyaddition process. In many processes PUR link with polyalkylene ether and polyester sequence with molecular mass 200 and 6000. This process is incomplete, and their growth is not supported by PUR. With the addition of carbon sources and nutrients, most of the degradation is carried by esterase.
