Zeon Chemicals has commercialized a thermoplastic vulcanizate with mechanical properties that open new possibilities for automotive under-the-hood applications. “Zeotherm is the first TPV capable of withstanding the 150 C under-the-hood environment common in today’s automobiles without suffering from severe degradation in automotive fluids,” explains Zeon marketing manager Brian Cail.

Zeotherm polymers also maintain performance at -40 C.

Potential applications include automotive shaft and bearing seals, transmission sealing components, inboard CVJ boots, air ducts, multilayer hose cover constructions and industrial goods.

The first grades to be commercialized are Zeotehrm 100-70B and 110-70B, both based on Zeon’s HyTemp polyacrylate elastomers (ACMs) dispersed in polyamide matrix.
