Germany’s Evonik has created a new combination of bio-based polyamides and bio-based fibres which the company claims offers CO2 savings of 67%.
The new range comproses two polyamide grades – Terra HS and Terra DS – which contain fibres derived from wood residues.
The company says reinforcing fibres are often added to a polymer to improve its mechanical properties, but they can lower the bio-content and ecological advantage. But Vestamid Terra retians the high-bio content as well as excellent reinforcing potential, it says.
The overall bio-content of the new materials is between 67-100% and the CO2 savings for a viscose fiber system of PA1010 with a fibre content of 30%, for example, are 57% higher than for a 30% glass fiber reinforced PA66.
And depending on fibre content, they offer a weight reduction of up to 10%, adds Evonik
