Seals & Gaskets


Ethylene acrylic elastomers offer superior sealing performance for aggressive fluids and high-heat environments

Our innovative product portfolio includes elastomers molded into black and colored seals and gaskets, O-rings, and bonded piston seals. Contact us to discuss new ideas that can help you make powertrain and thermal systems outperform the competition.


Reliable, long-lasting solutions

We work with compounders, molders, tiers, and manufacturers to address:

  • Cost efficiencies
  • Durability (heat and oil resistance)
  • Fuel efficiency 
  • Electrification (flame retardance, non-halogen and electrical conductivity/insulation)
  • Lightweighting
  • Noise, vibration, and harshness
  • Adhesion and/or compatibility with other substrates (metal and thermoplastic)


Superior product performance

Celanese Vamac® offers superior physical properties such as elongation, tensile and tear strength, low volume swell, permeation, and compression set over a broad range of hardness. In harsh environments, it provides excellent sealing for:

  • Static and dynamic seals and gaskets
  • O-rings
  • Membranes and bushings for engines
  • Transmissions
  • Air management applications for internal combustion engines and hybrids

Vamac® also provides excellent sealing performance for seals and gaskets used with various automotive fluids (engine oils, greases, transmission fluids, blow-by and exhaust gas acid condensates, EV fluids) that work in a wide range of temperatures. Multiple formulations enable us to develop compounds that meet the most challenging specifications.
