Over 25% bio-based material content in all membranes
In addition, global life sciences and materials sciences company Royal DSM NV, Heerlen/Netherlands, will launch mass-balanced bio-based Arnitel, a thermoplastic elastomer, together with Sympatex Technologies. Arnitel is manufactured with bio-based feedstock using a mass-balance approach. The end product contains more than 25% bio-based content by weight.
Sympatex uses Arnitel to manufacture its waterproof, windproof, and breathable membranes for sports applications. The transition to bio-based feedstock will maintain the functional properties of Arnitel and will enable Sympatex to shift to a more sustainable solution with a lower carbon footprint without having to requalify materials.
One of the first brands in whose collection this milestone will be effective is Mammut Sports Group AG, Seon/Switzerland, which will hit stores with a Sympatex collection in the coming winter season.
