Covestro has announced the launch of Desmopan FLY, an advanced Thermoplastic Polyurethane (TPU) series specifically engineered for supercritical fluid (SCF) foaming technology.

This high-performance material solution addresses the growing demand for lightweight, performance, and sustainable footwear design while expanding possibilities across sport gears, furniture and electronic products.

Desmopan FLY features an advanced formulation that enables superior supercritical fluid dispersion during the molding process, resulting in uniform fine-cell structured foams with outstanding mechanical properties. For footwear applications, this translates into midsoles with superior cushioning and energy return properties, and long-lasting comfort performance.

"Leading sports brands are driving unprecedented demand for materials that combine elite performance with strong environmental credentials,” says Wilson Chan, Head of Business Development TPU Asia Pacific at Covestro.

“Desmopan FLY brings exceptional lightweight and resilience properties while maintaining dimensional stability and durability throughout the product lifecycle. Its optimized processing enables efficient production through automated injection molding, allowing brands to create high-performance, recyclable footwear that meets demanding consumer expectations.”

Covestro has installed the advanced SCF injection foaming system at its TPU Asia-Pacific R&D Center in Taiwan. “Our investment in the SCF injection foaming system marks another milestone in Covestro’s continuous innovation journey,” explains Dr. Christian Haessler, Head of Global Innovation TPU at Covestro.

“This in-house capability enables us to optimize TPU material properties with precise SCF processing parameters. By being among the first in the industry to integrate this advanced technology within our R&D center, we can effectively combine TPU material and SCF injection expertise to accelerate customers’ development from concepts to commercial production.”
