Polyurethane (-40°C to +90°C)
Polyurethane is a more recently developed elastomer giving strength, abrasion resistance, tear strength and flexibility at low temperature.
Polyurethane is resistant to greases and mineral oils but will not withstand acids, non-mineral oils or water. Most widely used for its physical properties such as abrasion resistance.
