Functional fabric specialist Sympatex Technologies is using a new bio-based thermoplastic elastomer to manufacture its waterproof, windproof and breathable membranes for sports applications.

The Arnitel elastomer has been developed by the DSM Engineering Materials business of Dutch conglomerate Royal DSM. It is manufactured with bio-based feedstock using a mass-balance approach that has been designed to trace the flow of materials through a complex value chain. The end product contains more than 25% bio-based content by weight, according to the firm.

The transition to bio-based feedstock will maintain the unique functional properties of Arnitel and will enable Sympatex to easily shift to a more sustainable solution with a lower carbon footprint without having to requalify materials.

Caroline Mittlerlehner, vice president specialties DSM Engineering Materials, said the firms are working to drive the industry's transition from fossil-based to renewable resources.

Dr Rüdiger Fox, CEO of Sympatex Technologies, added: "We are seeing that partnerships such as ours with DSM accelerate the progress of our collective journey to a more sustainable world. Everyone in the value chain is benefiting, from suppliers to our customers and sports brands."
