Who are we?

Delivering the next generation of thermosets

At ExxonMobil we use advanced polymer technology to produce a new range of thermosets designed to outperform existing options. Our ProxximaTM products overcome traditional tradeoffs to deliver light-weight material with a superior balance of strength and toughness. Since becoming a wholly owned subsidiary of ExxonMobil in late 2021, we have been expanding our manufacturing and commercial capability, building the foundation to expand alongside the industry to realize the future of these highly dependable materials. 

ProxximaTM polyolefin thermosets provide a high-performance alternative to traditional choices, such as epoxy, vinyl ester and polyester. Built on Nobel- winning technology our resin systems deliver a step change in production economics. Specifically, our ultra-low viscosity and controlled fast cure dramatically improve processing speeds with minimal modifications to conventional processing equipment.

Our value chain partners continue to discover new potential for this technology. Contact us today.

What industries are using Proxxima™ technology?

    our products

    Proxxima™ polyolefin thermoset resin systems

    Our resin formulations are based on cyclic C5 monomers and other proprietary monomers and additives. Our catalyst formulations have strong foundations in Nobel Prize-winning technology developed by Professor Robert Grubbs and his research team. This powerful combination produces polymers that have the capability to outperform today’s solutions across a broad set of everyday applications such as wind turbine blades, electric vehicle parts, sustainable construction, and anticorrosion coatings.
