For applications requiring enhanced oil resistance that meets or exceeds that of nitrile rubber and epichlorohydrin. Geolast thermoplastic rubber is an oil-resistant thermoplastic elastomer (TPE) that performs with the versatility of rubber and processes with the efficiency of thermoplastic.

Geolast rubber features good retention of properties in hot air and hot oil aging, and provides a good combination of the low-temperature (-40°C [-40°F]) performance and the degree of oil resistance commonly associated with NBR and ECO rubber compounds. Parts made of Geolast rubber exhibit low oil swell, and the low compression set of Geolast rubber makes it suitable for use in sealing applications.
