Low Oil Swell and Low Compression Set Combine in Gaskets of Vamac®
DuPont™ Vamac® ethylene acrylic elastomers are useful in applications where combined heat and oil resistance plus exacting rubber-like mechanical properties are needed.
Properties of DuPont™ Vamac® contributing to long-life, heavy-duty oil pan and Cylinder Head cover gaskets include:
- Low melt viscosity, for molding and overmolding of long sections
- Excellent oil swell resistance, to help keep gasket thickness stable; no tendency to “weep” oil
- Low compression set
- Durable service to 165 °C (330 °F) continuous
- Excellent retention of sealing force at elevated temperatures
