What are Castable Polyurethane Elastomers?

A versatile family of materials, castable polyurethane elastomers has been used to produce the following articles: gears, sprockets, heavy duty truck bushings, skateboard and in-line skate wheels, mining sizing screens, energy-absorbing shoe soles, prototype parts, business machine and paper mill rollers, etc.

Castable polyurethanes are elastomers. They are available in a wide range of hardnesses and chemical compositions. Generally, they are considered to have outstanding physical properties including toughness, tear resistance, abrasion resistance, high load bearing capability, and good chemical resistance, to name but a few.

Castable polyurethanes are liquid at their typical process temperature of 150ºF. Therefore, they are usually processed by pouring into an open mold. This castability offers several advantages to a design engineer, including low mold cost as well as the ability to produce large parts or parts with thick wall cross-sections. In addition to open casting, these polyurethane materials may also be compression molded, spin cast, and transfer molded for even greater processing versatility.
