What is polyurethane made of?
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. Liquid
What are the elastic properties of polyurethane?
Polyurethane鈥檚 elastic properties are the result of a change in the distance between adjacent atoms 鈥?bond length 鈥?when under load. Hooke鈥檚 law will generally apply such that twice the force produces twice the stretch.
What determines the chemical resistance of a urethane part?
The chemistry used to produce a urethane part greatly influences its chemical resistance. Therefore, it is important to provide as much information as possible about the stresses and environment the product will see when in use.
