SYMPATEX GOES GREEN WITH ARNITEL® B-MB

In 2021 at the virtual ISPO Munich fair, Envalior and membrane manufacturer Sympatex Technologies introduced bio-based mass-balanced Arnitel®, a thermoplastic elastomer, which is manufactured with bio-based feedstock using a mass-balance approach—the end product contains more than 25% bio-based content by weight.  

Envalior and Sympatex have a long-lasting partnership in which we work together to reduce carbon footprint and use more sustainable feedstock sources for the Sympatex grade. This dedicated grade will now be replaced by the Arnitel B-MB version.

With this brand new range of mass-balanced bio-based Arnitel®, we are enabling Sympatex Technologies to make more sustainable choices for their new range of waterproof, windproof and breathable membranes for their outdoor sports apparel. Without having to requalify materials as the functionality and performance is exactly the same as the 100% fossil based grade, Sympatex is lowering their carbon footprint by using a more sustainable material. The first Sympatex customer to use Arnitel B-MB is Mammut, and its outdoor clothing collection Sympatex (B-MB).

What is the mass balance approach?

Mass balance accounting is a well-known approach that has been designed to trace the flow of materials through a complex value chain. The mass balance approach provides a set of rules for how to allocate the bio-based and/or recycled content to different products to be able to claim and market the content as ‘bio’-based or ‘recycled’-based.
