ExxonMobil Acquires Nobel‑Prize‑Winning Composites Firm Materia

ExxonMobil Chemical Co. has acquired California‑based Materia Inc., the pioneer behind a Nobel Prize‑winning technology for producing high‑performance thermoset resins. These materials—suitable for wind turbine blades, electric‑vehicle (EV) components, sustainable construction, and anticorrosive coatings—combine steel‑level strength and stiffness with dramatically reduced weight, according to Materia President and CEO Cliff Post.

Founded in 1999, Materia has built its reputation on a new class of ruthenium catalysts and ring‑opening metathesis polymerization (ROMP) chemistry invented by Caltech Professor Robert Grubbs, the 2005 Nobel laureate in Chemistry. The acquisition integrates Materia’s breakthrough technology with ExxonMobil’s proprietary processes and world‑class manufacturing capabilities, enabling these sustainable structural polymers to reach larger commercial scale.

Proxima Resins: Unmatched Toughness and Versatility

Proxima thermosets are two‑part systems engineered with proprietary blends of dicyclopentadiene (DCPD) and co‑monomers, providing precise control over performance and reactivity. Unlike conventional thermoset resins—epoxies, vinyl esters, and polyester resins—Proxima resins are not brittle. They deliver exceptional toughness, durability, corrosion resistance, and a broad operating temperature range.

These resins combine the heat tolerance and processability of a thermoset, the impact strength and damage tolerance of a thermoplastic, and the low moisture absorption and corrosion resistance of a fluoropolymer. Materia offers a portfolio of formulations that balance stiffness, impact strength, and heat deflection, including toughened and high‑heat neat resins, carbon‑fiber composites, glass‑fiber composites, and syntactic foams.

Proxima is engineered for industry‑standard manufacturing processes: reaction injection molding (RIM), resin transfer molding (RTM), vacuum‑assisted resin transfer molding (VARTM), and rotomolding.

Expanding Proxima’s Reach into EV Parts and Renewable Energy

Since 2017, ExxonMobil and Materia have collaborated under a joint development agreement to explore new applications for Proxima, such as wind turbine blades and anti‑corrosion coatings. The technology could enable longer, more durable blades that boost renewable energy efficiency. ExxonMobil also plans to broaden Proxima’s use in EV components and sustainable construction projects.

With early support from Caltech and private investors, Materia has already secured commercial deployments in oil and gas and industrial molding. In 2016, the U.S. Department of Energy awarded a $2 million grant to investigate molding hydrogen tanks from a Proxima carbon‑fiber composite.

The acquisition includes Materia’s extensive patent portfolio, intellectual property, headquarters, and research center in Pasadena, CA, and a manufacturing facility in Huntsville, TX. ExxonMobil will operate the business as a wholly owned subsidiary under the Materia name, leveraging its proven expertise and ExxonMobil’s manufacturing excellence.
