The production of polyurethane (PUR) applications requires a good knowledge of the individual used substances as possibilities in compounding are unlimited. For many polymer scientists interest in the material composition appears as there might happen unexpected side reactions as well specific defects might appear in the final product (foam collapsing, delamination, blooming, cracking, smelling, yellowing, etc…). Not always a physical reason can be found when speaking about material properties but the analyst should go back to the chemical structures when formulating an explanation
