Why Proxxima™ technology is enabling a breakthrough for construction

Why Proxxima™ technology is enabling a breakthrough for construction

Proxxima™ resin systems from ExxonMobil are enabling the production of innovative composite materials. Because these materials are lighter and stronger than steel, they have the potential to help lower labor and transportation costs, enabling the construction industry to build more efficiently without sacrificing durability.

How can higher
strength mean lower emissions?

The unique chemistry and production process of Proxxima™ technology means it has less than half the greenhouse gas emissions of many traditional thermoset resins3. So not only can it advance innovation for construction, transportation, and manufacturing, it can do so while lowering emissions. It’s one way ExxonMobil is helping to deliver a lower-carbon future.

Source: Carbon Footprint of Product of Reinforcing Bars: Steel and Proxxima™ Resin containing Glass Fiber Reinforced Polymer (GFRP) in Construction Applications, May 2025, prepared by ExxonMobil Technology and Engineering Company. The study was conducted to be in accordance with ISO 14067:2018 (Greenhouse gases – Carbon footprint of products – Requirements and guidelines for quantification). The study was confirmed to be conducted according to and in compliance with ISO 14067:2018 by an independent third party (Sphera Solutions, Inc.) critical review which followed ISO 14071:2024 to support comparative environmental footprint communications as defined in ISO 14026:2018.

  3. Comparative carbon footprint of product estimate study: ExxonMobil’s Proxxima™ Resin Systems, June 2023, prepared by Sphera Solutions, Inc. for ExxonMobil Technology and Engineering Company. The study was confirmed to be conducted according to and in compliance with ISO 14067:2018 (Greenhouse gases - Carbon footprint of products - Requirements and guidelines for quantification) by an independent third party critical review panel. All resins assessed in this Life Cycle Assessment (LCA) study were of the type used in molding applications. Specifically, the epoxy resin system was of the type used in VARTM wind blade production. The resin systems are representative of formulated resin systems and include any required curing hardeners or catalysts. https://www.proxxima.com/en/what-is-proxxima/sustainability
