Advanced materials and specialty additives firm Eastman Chemical Company said it has developed a “breakthrough” bioplastic product geared toward end users with rigorous sustainability and performance needs.

“Eastman leveraged nearly 100 years of cellulosic expertise in the design and testing of TREVA to meet the improved sustainability profile and performance needs of brands, fabricators, molders, and other companies across the value chain,” said a statement by Burt Capel, vice president and general manager of Eastman’s specialty plastics unit.

Announced by a May 15 press release and debuted at the Chinaplas Plastics & Rubber Trade Fair in Guangzhou, China, the composition of Eastman’s BPA- and phthalate-free material TREVA is about half cellulose sourced from sustainably-managed trees.

“Its excellent flow rates, durability, and dimensional stability allow for less material usage, thinner parts, and longer product life, enhancing lifecycle assessments,” the company’s release said.

TREVA, which features high chemical resistance, is ideal for end use in a number of consumer products like electronics, cosmetics cases, eyeglass frames, and automotive interior components, the company said.

“Excellent flow characteristics also enable design freedom, allowing TREVA to be used with complicated designs and in filling thin parts. Under recommended processing conditions, recent thin-wall 30 mil spiral flow testing shows that TREVA flow rates are significantly better than polycarbonate and polycarbonate/ABS blends, and comparable to ABS,” Eastman said in its release.
