Eastman Crystex™ insoluble sulfur celebrates 75th anniversary

Eastman is committed to honoring a legacy of innovation.

AKRON, Ohio, July 30, 2019 – As Eastman Crystex™ celebrates its 75th year, the team behind the world’s leading insoluble sulfur brand remains focused on developing the next breakthrough for the tire and rubber industry.

The Crystex story began in 1944 when Stauffer Chemical Company filed a patent for its insoluble sulfur product. The name Crystex evolved from “No Crystals” and “Crystals-X” as a literal explanation of the product function and benefit to tire makers. The brand grew, and high thermal stability grades were introduced. In a short time, Crystex became known for providing robust properties that tiremakers needed as they innovated and operated in more challenging production environments.

“Crystex’s history has been rooted in technological leadership. From its initial patent to our nomination for Innovation and Excellence in the Tire Technology of the Year category at Tire Tech 2019, the Crystex story is one of helping customers make tires more efficiently,” said Dr. Brock Thomas, technology director of Eastman Tire Additives. Another Crystex milestone came at about the half-century mark with the introduction of improved dispersion grades, which provided processing benefits in rubber mixing operations without sacrificing critical properties. The market-leading brand became part of the Eastman portfolio with the acquisition of Solutia in 2012. Since then, Eastman has focused on advancing the Crystex technology to meet the growing needs of the tire and rubber industry.

“Eastman takes great pride in how we honor the legacy of the Crystex brand and what it stands for,” said Gunes Celik, vice president and general manager of Eastman Tire Additives. “New innovations that carry the name must meet extremely high standards and deliver the level of performance and quality the industry associates with Crystex.” For decades, the Crystex brand has been considered the industry standard for insoluble sulfur. That legacy continues with the launch of Crystex Cure Pro - the newest innovation and latest addition to the Crystex product line. Crystex Cure Pro was developed at Eastman’s technology center in Akron.

As tire makers search to optimize their energy, labor and capital costs, increased productivity becomes an even more important consideration. Based on a legacy of proven innovation, Crystex Cure Pro gives tire makers a unique advantage to gain efficiency in the production environment without sacrificing quality.
