Benefits & Compound Options

Conti Convoluted Air Springs are rated to 6 million cycles!

Quality Compounds

1. Natural Rubber (NR)

   • Standard Material for Convoluted Bellows
   • Very high dynamic capability
   • Excellent universal properties

2. Chloroprene-Rubber (CR)

   • Standard Material for Model Series S
   • Very high weathering resistance
   • Higher oil and temperature resistance than NR
   • Temperature range similar to Dunlop Butyl

3. Epichlorohydrin Rubber (ECO)

   • For high-temperature applications
   • Resistant to mineral oils and fuels

Continental Engineering Advantage

• Elastomer Compound Temperature Range
  • NR (Natural Rubber): Standard material for convoluted bellows; offers excellent universal properties.
  • CR (Chloroprene Rubber): Standard material for Series S; offers excellent weathering resistance, good oil & temperature resistance.
  • ECO (Epichlorohydrin Rubber): For high-temperature applications, resistant to mineral oils and fuels.
