Double Coin tyre experts praise Crystex Cure Pro

Double Coin Tires engineers praised the benefits of Eastman’s Eastman Crystex Cure Pro insoluble sulphur alongside scientists from the chemicals manufacturer Eastman during a joint speech at the China Rubber Industry Association (CRIA) conference on 15 September. Around 200 professionals from tyre-related enterprises gathered at the conference to discuss the latest industry technologies and market status.

According to its manufacturer, Eastman Crystex Cure Pro insoluble sulfur, the newest addition to the Crystex product line, has “multiple unique features that enable substantial tyre quality and operational cost savings”. Benefits are said to include: faster dispersion, enhanced thermal stability and superior flow.

“We were most impressed by the enhanced thermal stability and improved dispersion of Cure Pro compared with HD OT 20, as proved via high thermal stability (HTS) testing results,” said Jiang Qi, vice director of Double Coin’s research centre, who spoke about the application research report on Cure Pro. “After years of research, we have successfully developed our own HTS measurement technique which is efficient with less manual dependence compared with the conventional measurement technique.”

Eastman and Double Coin describe their relationship as “strategic partners”. “Double Coin was the first tyre company to visit the newly built Eastman Tire Additives Shanghai lab,” said Dr. Steven Gao, Eastman’s Asia-Pacific application development and technical service group leader for Tire Additives, who spoke with Jiang Qi. “The new lab was opened in 2019, equipped with analytical, rubber compounding, and rubber testing equipment and providing the same state-of-the-art service as Eastman’s world-renowned tyre technology center in Akron, Ohio.”

“These facilities, along with manufacturing centres in every region, help us be close to the customer while providing global security of supply,” said San Sutanto, Eastman’s Asia-Pacific sales director for Tire Additives. “We are also very proud that Eastman was recognized as Supplier of the Year at the 2020 Tire Technology Expo Awards for Innovation and Excellence. Eastman will continue to relentlessly focus on innovation for and cooperation with customers.”
