Polyurethane Properties are measured by many physical properties such as hardness, compression set, ultimate tensile strength, tensile modulus, tensile set, elongation, tear strength, compression deflection, and abrasion resistance to mention a few. The end result is that when compared to other “elastomers”like rubber or metals like steel and aluminium, polyurethane stands out in several areas and can be utilized in place of or in conjunction with other engineered materials to achieve the perfect part for nearly any application.
