Reduce costs, add service life to expansion joints with Santoprene™ TPVs
Santoprene thermoplastic vulcanizates (TPVs)  provide outstanding toughness and longevity to expansion joints for bridge and parking decks; water stops; rail pads and more. Consider general purpose or UV-resistant Santoprene TPV grades to cost effectively achieve excellent low-temperature flexibility and flex-fatigue resistance.

Resilient and long-lasting seals

  • Stands up to ozone, UV exposure, road salt solutions, acids, cleaning fluids and chemical wastes
  • Consistent flexibility and performance in harsh conditions
  • Outstanding flex-fatigue resistance, proven by more than 2 million cycles of flexing (ASTM D1052), exceeding neoprene and ethylene propylene diene monomer (EPDM) capabilities

Precise fit and design flexibility

  • Easy color matching and coextrusion options for improved attachment designs
  • Consistent fit of profile into attachment system

Using less, delivering more

  • Time and cost savings with heat-weldable corners; no adhesives or vulcanization required
  • No VOCs required as with solvent bonding of thermoset rubber joints
