Properties of Polyurethane Foams
8.2.1 Properties of Hyperelastic Polyurethane Foams
Hyperelastic polyurethane foams are produced in the process of foaming polyurethanes, with the use of cross-linkers, foaming agents and catalysts. In the production of these types of foams, it is important that after seasoning the block, a mechanical opening of closed pores takes place. Properly opened pores provide the level of flexibility of the foam.
Foams are one of the basic materials used in the construction of subassemblages of upholstered furniture, both with springs and without springs. In particular in the latter, polyurethane foams form an essential part of the upholstery construction...
