polyetherpolyurethanes

Polyetherpolyurethanes are a class of polymers belonging to the polyurethane family. They are characterized by the presence of ether linkages within their polymer backbone. These materials are synthesized through the reaction of diisocyanates with polyols, where at least one of the polyols used is a polyether polyol. The ether linkages contribute to the flexibility and hydrolytic stability of the resulting polyurethane.

The properties of polyetherpolyurethanes can be widely varied by adjusting the type and ratio of the reactants, including the specific polyether polyol and diisocyanate chosen, as well as the addition of chain extenders and catalysts. They are known for their good low-temperature flexibility, resistance to abrasion, and in many cases, excellent resistance to hydrolysis and microbial attack. These attributes make them suitable for a broad range of applications.

Common uses for polyetherpolyurethanes include flexible foams found in furniture and bedding, coatings for textiles and leather, adhesives, sealants, and elastomers for applications such as shoe soles, automotive components, and medical devices. Their versatility and tunable properties allow for their use in demanding environments where durability and specific performance characteristics are required.
