Polyurethane Foam
Polyurethane is produced in a polymerisation reaction between polyols and isocyanates. Polyurethane foam can be of flexible as well as rigid nature. Polyurethanes exhibit good mechanical properties retention at low temperature, good processing characteristics, high elasticity and excellent mechanical properties.
There are large number of polyols and isocyanates available to produce polyurethane, a broad variety of materials can be produced to meet the needs of specific applications. Light weight nature and versatility makes it an optimal material in construction, marine, automotive and footwear industries. Flexible polyurethane foam is light, durable, supportive and comfortable. It is commonly used for cushioning in bedding, furniture, automotive interiors, carpet underlay and packaging. Rigid polyurethane foam is used in support structures, roofs, windows, walls and refrigeration for sound reduction and thermal insulation. Rigid foam is also used to provide support to weak and flexible membrane.
