BASF, a global leader in chemical innovation, and Hagihara Industries, a leading synthetic fiber producer in Japan, have joined forces to develop highly durable polyolefin yarns for artificial turf used in sports arenas, including football stadiums, baseball fields, and tennis courts.

After three years of collaborative research and development, the two companies have created an advanced formulation with a series of Tinuvin grades that significantly enhances the durability of synthetic grass, making it less susceptible to damage from sun exposure and ensuring it retains its vibrant color.

"One of the challenges we faced in producing yarns for artificial grass was improving its ability to endure relentless exposure to sunlight and extreme weather conditions,” said Norio Funakoshi, Chief of Fundamental Research Section, Hagihara Industries, Inc. “As our customers were looking for enhanced durability, BASF stepped in to address this issue by recommending the ideal blend of additives,” added Funakoshi.

BASF’s range of light stabilizers are designed to convert UV rays into harmless thermal energy, serving as an umbrella to shield against the sun's damaging effects. Certain UV rays can attack polymers, compromising their strength and elongation. However, with the use of selected Tinuvin grades, this radical reaction can be effectively prevented.

Hagihara Industries successfully incorporated the advanced formulation of these additives into their yarn manufacturing process, which resulted in the production of artificial turf that lasts up to 10 years. Fagiano Okayama, a J-League football club located in Okayama Prefecture, manages the company's exceptionally durable artificial turf on its practice field. The turf has been acclaimed for its quality.

“We are thrilled to highlight the fruitful partnership between BASF and Hagihara Industries,” said Hazel Sprafke, Vice President, Global Business Management, Plastic Additives, Asia Pacific. “This collaboration exemplifies our commitment to addressing our customers' needs through continuous innovation and effective solutions.”
