Teijin Frontier Develops World’s First Tire Cord Made from
Eco-friendly Adhesive and Recycled Polyester
Tokyo, Japan, September 12, 2022 --- Teijin Frontier Co., Ltd., the Teijin Group's fibers
and products converting company, announced today that it has developed an eco-friendly
tire cord made from an adhesive that does not contain resorcinol formaldehyde (RF),which is harmful to the human body and the environment, and also incorporates alow-environmental impact chemically recycled polyester fiber for rubber reinforcement.
According to the company, this is the world's first commercialization of a tire cord thatcombines an RF-free adhesive and a chemically recycled polyester fiber.

Teijin Frontier’s new tire cord

Teijin Frontier will now begin to develop reinforcing-fiber applications for various rubber
products, including tire cords, belts, hoses and other diverse uses. The company will start
test production of its new tire cord in 2023, targeting annual production of 200,000 tons by
2030.
Teijin Frontier, guided by its THINK ECO® environmental initiative, is striving to improve
its environmental value by developing greener materials and products for applicationsranging from clothing to industrial materials. The new tire cord is a result of thecompany’s increasing emphasis on low-environmental impact solutions.
Thanks to its use of an adhesive polymer compound instead of RF, the new tire cord
reduces the environmental impact of adhesive processing. In addition, due to its strong
affinity with fibers and rubber, its adhesion performance is equivalent to that ofconventional resorcinol-formaldehyde-latex (RFL) adhesives. Also, its chemicallyrecycled fibers, which are made from polymers produced with chemical recycling method,maintain their strength, fatigue resistance, dimensional stability and heat resistance.
Compared to conventional tire cords made from petroleum-derived polyester fiber, thenew tire cord achieves the same levels of quality and performance in addition to reducing
CO2 emissions during production.
The demand for more eco-friendly tires is growing due to rising environmental awareness.
In response, Teijin Frontier has been actively developing eco-friendly materials andproducts for tires as well as other rubber products. In 2008, it launched the world's firsttire cord incorporating chemically recycled polyester fiber, and in March 2020 thecompany introduced an eco-friendly rubber-reinforced fiber cord that does not containRF.
The newly developed tire cord will be exhibited at the International Tire Exhibition andConference, one of North America's largest tire-related exhibitions and conferences, inAkron, Ohio from September 13 to 15.
