Characteristics and Usage of polyurethane


Introduction
Polyurethane is divided into polyester type and polyether type two major categories.Polyurethane has many excellent properties, so it has a wide range of usage.

Characteristics & Main Usage
Because the polyurethane macromolecules contain a group of strong polar groups, and macromolecules also contain polyether or polyester flexible chain segments, so that polyurethane has the following characteristics:
① High mechanical strength and oxidation stability;
② Has high flexibility and resilience.
③ Has excellent oil resistance, solvent resistance, water resistance and refractory.
Polyurethane has many excellent properties, so it has a wide range of uses.
Polyurethane is mainly used as polyurethane synthetic leather, polyurethane foam, polyurethane coating, polyurethane adhesive, polyurethane rubber (elastomer) and polyurethane fiber. In addition, polyurethane is also used in civil construction, address drilling, mining and petroleum engineering, the role of water shutoff, building or roadbed, as a paving material for the sports field runway, the building of the interior floor.
