Polyurethane is among the very best engineering polymers. It is flexible and customized to achieve particular homes such as high tack adhesives, versatility, foam flexibility or hardness. The attributes depend upon the design of the urethane linkage with aliphatic hydrocarbons, esters, amides, and other organic compounds. Adhesives are one location in which polyurethane material radiates. It can also handle epoxy, proving to be better in many cases, such as footwear, where flexibility is essential. Polyurethane adhesives producers provide adhesives specifically engineered for usage for footwear. Not that is the only use to which they are put!

Uses for polyurethane adhesives
