Elastomeric Composite Materials

In geothermal energy extraction, elastomeric materials are used in variety of equipment, including zonal isolation devices/packers, downhole pumps/valves/motors, and other wellbore/reservoir monitoring tool. Depending on the specific application, the elastomeric material can see elevated temperatures of greater than 225°C for long-term applications months to years) and 300°C for shorter duration applications days to weeks. High heat and temperature spikes can degrade elastomeric seals causing their crosslinking structure to become irreversibly damaged. When elastomers are used above their maximum continuous service temperature limit over time, they can become hard and brittle, thereby losing their ability to maintain effective sealing. The results can be unscheduled downtime, potential product loss or even worse, possible safety threats to the work environment. In this Phase 1 SBIR proposal, Vuronyx Technologies will collaborate with Prof. Satish Kumar at Georgia Institute of Technology, and utilize their joint experience to tailor the interphase between CNTs and elastomeric rubber. The reinforced elastomeric material will have improved thermal, mechanical, and abrasion resistance properties. Feasibility will be established by coupon development and laboratory testing/demonstration of materials for wear and physical deformation crush) resistance and accelerated environmental effects testing. Mechanical testing will be performed in a simulated geothermal environment. Feasibility will be established by coupon development and laboratory testing/demonstration of materials for wear and physical deformation crush) resistance and accelerated environmental effects testing salt water, UV, and various fuels and oils). Global Elastomers market accounted for $71.89 billion in 2017 and is expected to reach $129.14 billion by 2026 growing at a CAGR of 6.72% during the forecast period. These elastomers are generally used to manufacture various products such as microcellular gaskets and foam seals, elastomeric wheels of roller coaster, elevator, shopping carts, automotive suspension bushings, surface coatings, sealants and many more. Rubber gaskets are used to make doors, hatches, and various other machinery interfaces water- or weather-tight. Due to the remote operating areas, harsh environments, and limited space available onboard ships, oil rigs, and other marine platforms, reliable sealing mechanisms are extremely important. Additional commercial applications include improved abrasion resistant elastomer products and sports equipment.
