Zeotherm ® TPV

Resistance to Aggressive Fluids

  • Greases are not "dried out" by Zeotherm TPVs, because Zeotherm does not extract oil from greases, allowing them to retain their lubricity.
  • Zeotherm TPVs are better able to withstand aggressive greases used in automotive constant velocity joints (CVJ), unlike copolyesters, which are severely damaged by common hot greases.
  • Unlike silicone rubber, Zeotherm TPVs resist swelling in hot oil and have superior retention of mechanical properties.

Zeotherm TPVs are far superior to conventional TPEs and copolyesters in applications that require exposure to automotive fluids. In fact, Zeotherm is able to resist the most aggressive automotive fluids - including engine oil, transmission fluid and lubricating greases – for the life of the vehicle, even when those fluids are hot. Tests shows Zeotherm TPV components far outperform components made of silicone rubber and copolyester when exposed to oils and lubes at 150°C/300°F. Zeotherm TPVs are even suitable for many applications with occasional (or "splash") contact with coolants or fuel. An excellent choice for a wide range of components, Zeotherm provides better fluid and heat resistance than any other commercially available thermoplastic elastomer.

  • Resists automotive fluids including engine oil, transmission fluid (ATF), coolant, fuel and grease
  • Provides superior oil resistance over silicone rubber
  • Resists aggressive greases used in steering, axle and driveshaft joints
  • Won't dry out greases and lubes like conventional TPEs and copolyesters can
  • Maintains fluid resistance over a wide temperature range (-40° C to 175° C)
