Polyurethanes in Footwear.
Polyurethanes allow designers to meet all of these objectives. Light but highly abrasion-resistant polyurethanes are perfect for hardwearing shoe soles with excellent long-term mechanical properties. Polyurethane soles are practical and keep water out while in no way limiting design potential. Within the shoe sector polyurethanes are found in a wide range of footwear types. Although best known for sports and trekking shoes and boots they are also extensively used for business and fashion shoe soles as well as high-quality safety shoes. Low-density to compact polyurethane systems are utilised for mid-soles and outer soles. People often stop wearing shoes merely because they have gone out of fashion but the durability of polyurethanes ensures that shoes containing this material have considerable second-hand value.

Polyurethane Wikipedia.
Jump to navigation search. Polyurethane synthesis wherein the urethane groups NHCOO link the molecular units. Polyurethane PUR and PU is a polymer composed of organic units joined by carbamate urethane links. While most polyurethanes are thermosetting polymers that do not melt when heated thermoplastic polyurethanes are also available. Polyurethane polymers are traditionally and most commonly formed by reacting a di or poly isocyanate with a polyol. Both the isocyanates and polyols used to make polyurethanes contain on average two or more functional groups per molecule. Some noteworthy recent efforts have been dedicated to minimizing the use of isocyanates to synthesize polyurethanes because the isocyanates raise severe toxicity issues.
Recticel What is Polyurethane?
Polyurethane PU stands for an important group of products within the big family of polymers or plastics. PU is a generic name for a wide range of foam types. The structure of PU foam consists of a network of dodecahedron cells which behave as micro-springs. The properties of PU depend on. the chemical composition and thickness of the cell walls. the volume-solid matter/air ratio. the concentration of the cell membranes air permeability/open cell structure.
