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

DuPont™ 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.

Seal and gasket solutions are further enabled by DuPont™ MEGUM™ and THIXON™ specialty adhesives that provide adhesion to multiple substrates for those applications that require bonding.
