Polyurethane Technical Data Polyurethanes are some of the most versatile plastic materials to date. Polyurethane routinely outperforms plastic, rubber and steel in its overall ability to resist harsh environmental factors such as abrasion, heat, solvents, oil and acid. The kaleidoscopic forms of nature and the vibrant sources of self-cleaning natural surfaces, such as the self-cleaning properties and robustness of lotus leaves, the bactericidal properties of the wings of cicada, the structural color of butterfly wings, the ability to walk on water of the water strider, that of the gecko to walk on vertical surfaces, the antireflective and antifogging. Wind energy is considered a clean energy source and is predicted to be one of the primary sources of electricity. Polyurethane’s hardness range straddles typical rubber and plastic hardnesses. We have a wide range of proven polyurethane compounds and the ability to formulate compounds to meet the specific needs of our customer's projects. The main components of polyurethane insulation pipe: 1. Depending on the chemistry formulation and the reaction process, polyurethane’s end-state performance is tailorable to meet exactly what you need. Durometer measures the hardness of an elastomer, similar to Rockwell hardness for steel. . pornsite list
