Isingeniso: Abakaki bePolyurethane badlala indima ebalulekile embonini yamakhemikhali, ikakhulukazi ezinhlelweni zamapayipi wamakhemikhali. Njengokusebenza okuhlukahlukene, i-polyurethane inikeza izinzuzo eziningi ezithuthukisa ukusebenza kahle nokuqina kwalezi zibakaki. Kule ndatshana, sizohlola izici, izinhlelo zokusebenza, nezinzuzo zamabakaki we-polyurethane, ukukhanya kokubaluleka kwabo ku-c
