Polyurethane Applications
Nov 28, 2017

Heating and cooling costs amount to about 56 percent of the energy used in the average American home, according to the U.S. Department of Energy. The nature of the chemistry allows polyurethanes to be adapted to solve challenging problems, to be molded into unusual shapes and to enhance industrial and consumer products.

Polyurethanes are formed by reacting a polyol (an alcohol with more than two reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives. Because a variety of diisocyanates and a wide range of polyols can be used to produce polyurethane, a broad spectrum of materials can be produced to meet the needs of specific applications.

Types of Polyurethane:

Flexible Polyurethane Foam
Flexible polyurethane foam is used as cushioning for a variety of consumer and commercial products, including bedding, furniture, automotive interiors, carpet underlay and packaging. Flexible foam can be created in almost any variety of shapes and firmness. It is light, durable, supportive and comfortable.

Flexible polyurethane foam accounts for about 30 percent of the entire North American polyurethane market, and is used largely for bedding, furniture and in the automotive industry.

Rigid Polyurethane Foam
Rigid polyurethane and polyisocyanurate (polyiso) foams create one of the world's most popular, energy-efficient and versatile insulations. These foams can significantly cut energy costs while making commercial and residential properties more efficient and comfortable.

According to the U.S. Department of Energy, heating and cooling account for about 56 percent of the energy use in a typicalU.S.home, making it the largest energy expense for most homes. To maintain uniform temperature and lower noise levels in homes and commercial properties, builders turn to rigid polyurethane and polyisocyanurate foam. These foams are effective insulation materials that can be used in roof and wall insulation, insulated windows, doors and air barrier sealants.
