In South Korea, SK chemicals is supplying its biobased material ECOTRION to the 2025 Z-Star series golf balls from SRIXON, a global golf brand under Dunlop Sports Korea.
ECOTRION is a biobased polyol made entirely from 100% bioderived ingredients. The material is characterized by “excellent” elasticity, resilience, and abrasion resistance, making it suitable for use in applications such as urethane and spandex. According to Dunlop’s research lab, the contact time at impact for the New Z-Star Series, which uses ECOTRION in the ball cover, increased by up to 18% compared to the company’s previous models.
The New Z-Star Series is chosen by top global tour professionals such as Brooks Koepka and Hideki Matsuyama, as well as many players on the Korea Professional Golfers’ Association Tour.
“With global interest in sustainability on the rise, the golf industry is also making various efforts to reduce carbon emissions and improve environmental impact,” Dunlop said in a press statement.
