In … Electrical Properties Polyurethanes exhibit good electrical insulating properties. Currently, polyurethane (PU)-based coating has entered a stable and rapid development stage, 1 –3 but its application was limited by some drawbacks such as poor surface properties, low mechanical strength, and poor water resistance. This durability often means that a part made from polyurethane can be made with less material and weight, reduced maintenance, and lower cost. PROPERTIES OF THE POLYURETHANE (PU) LIGHT FOAMS ABSTRACT The report presents results of laboratory investigations made on the PU foams. The proper selection of the right polyurethane depends on a variety of … Therefore, some researchers modified the PU materials by introducing epoxy resin, fluorosilicone, and nanoparticles. Polyurethane has been used in potting and insulation compositions at frequencies up to 100 kilohertz at temperatures at 100°C (212°F). Among the many variations are polyurethanes with properties tailored for automotive applications, such as bumpers, and others that are molded with a foaming agent to create rigid or flexible foams. Mechanical properties of foams have been measured in compression tests for two foams of 16 kg/m 3 and 62 kg/m density, and in tension and shearing tests for foam of 62 kg/m3 density. The one true Achilles Heel of molded polyurethane is heat. Our Products. The Plei-Tech ® name is known globally as a quality, high performance polyurethane. They are needed everywhere. modified the PU coatings by … In applications where severe wear is a problem, polyurethanes often outperform rubber, plastics, or even metals. Abstract: The effects of carbon black N990 on polyurethane properties with different weight fraction (2, 4, 6, 8, and 10 wt%) of the former were investigated in terms of tensile strength, hardness, impact strength, flexural strength, and density.
