Properties and Applications of Polyurethanes

Properties of Polyurethanes

1. Polyurethane has high load capacity in both tension and compression that may change shape under heavy load but will return to its original shape once the load is removed with little compression.

2. Polyurethanes possess high fear resistance along with high tensile properties.

3. Polyurethane material will remain stable with minimal swelling in water, oil, and grease.

4. Polyurethanes exhibit good electrical insulating properties.

Applications of Polyurethanes

1. Polyurethane foam is used for furniture stuffing, carpet backings, and insulation.

2. One of the most important uses of polyurethanes is in fabrics with elastic properties, such as spandex.

3. Polyurethane materials are commonly formulated as paints and varnishes for finishing coats t protect or seal the wood.

4. Polyurethane is also used in making solid tires and garments.
