Case Study: Durable automotive hoses of Vamac® retain elastomeric properties
Vamac® elastomers are used in a wide variety of automotive hoses, subjected to punishing temperatures and chemical exposures.
Application Description
Automotive hoses made with DuPont™ Vamac® ethylene acrylic elastomer.
Materials Selected and Why
Vamac® is chosen for a wide variety of hoses since it has:
- Ability to retain elastomeric properties from continuous temperatures of -40°C (-40°F) to 165°C (330°F)
- Tear and abrasion resistance
- A low compression set, which helps retain sealing force at fittings
- Properties that help isolate and dampen vibration
- Excellent chemical resistance, including engine oils and diesel fuels
