High-performance bio-based fibre now available for product designers

DSM - in partnership with other large companies - has developed Dyneema, a bio-based fibre (ultra-high molecular weight polyethylene).

Dyneema is the UHMWPE fibre (ultra-high molecular weight polyethylene) in the DSM range. It is best known for its excellent fatigue, chemical and abrasion resistance together with its strength / weight ratio, which is one of the best among high-performance polymer fibres.

In early 2020 DSM announced a partnership with Sabic, a global leader in the chemical industry, and UPM Biofuels, which produces sustainable raw materials. The goal of this new partnership is to reduce Dyneema's environmental footprint by making the transition to bio-based raw materials.

UPM Biofuels produces BioVerno organic raw materials using residue from the wood-pulp industry. The materials are treated by Sabic to produce ethylene via its Trucircle process, which is applied to certified renewable products that do not compete with the food chain and help cut carbon emissions.

DSM has set a target of using 60% organic raw materials by 2030. The transition is designed to retain the fibre's performance.

The bio-based Dyneema material will carry the ISCC Plus certification, the international sustainability standard applicable to all sectors that use raw materials of plant origin or derived from recycling.
The fibre will be available from April 2020.
