Polyurethane routinely outperforms plastic, rubber and steel in its overall ability to resist harsh environmental factors such as abrasion, heat, solvents, oil and acid. Materials suitable for electrical insulators have high dielectric strength and resistivity and low dielectric constant and power factor. Polyurethane foam is also considered to be a more economical cost in relation to sponge materials. To understand the properties of polyurethane foam, a clear distinction must first be made between these two. Polyurethane Structure [2]. Rigid polyurethane foams have become widely used as insulation materials because of their combination of low heat transfer and good cost effectiveness. Polyurethane is a closed-cell foam insulation material that initially contains a low-conductivity gas in its cells. Because urethane is available in a very broad hardness range (eraser-soft to bowling-ball-hard), it allows the engineer to replace rubber, plastic and metal with the ultimate in abrasion resistance and physical properties. TPU provides a large number of physical and chemical property combinations for the most demanding applications such as automotive, wires and cables, breathable films for leisure, sports and textile coatings, weatherable, non-yellowing films etc. Blowing agents/surfactants To aid the production of PU foams, to help. Use as insulation and other applications are restricted by an upper temperature capability of about 250 F. Polyurethanes do not survive well in direct sunlight or in contact with most organic solvents. PO-652. Typically, clothing made of this fabric is designed to hold its properties through at least 100 cycles in the washer and dryer without harm to the material.

Due to their good balance of physical properties, polyesters also provide excellent damping solutions such as shock and vibration absorbers.. Compression set: (ASTM D395-03 (2008) Method B) 22 Hrs. The first type of flexible polyurethane foam to be developed was polyester foam in the early 1950s. The first Polyurethanes were manufactured as millable gums and so could be processed on normal rubber manufacturing equipment. With the development of polyether based polyols in the late 1950s, polyether foams offering a wider range of properties started to be manufactured. Nevertheless, these foams can be useful (depending on formulation) to temperatures as high as 275 degrees F, while retaining a substantial portion of their strength and toughness.
