Indorama advances sustainable polymers for tire fibres

Bangkok, Thailand – Indorama Ventures has advanced sustainability efforts with the production of 100% bio-based polymers for tire and other speciality applications.

The high-tenacity PA4,10 yarn is manufactured at the group’s site in Obernburg, Germany, and is produced from ‘mass balanced’ 100% bio-based sebacic acid and bio-based di-amino butane.

The Thai-based chemicals group said it also achieved ISCC+ certification for two other fibre manufacturing sites in Italy and China.

Both units, it said, are supplying technical yarns for applications in mobility, tire cords, airbags as well as industrial and technical rubber goods.

Among other products, Indorama now produces ‘mass balanced’ PA6,6 and PA4,6 at its sites in Obernburg and Pizzighettone, Italy, the group said 4 Sept without specifying the sustainability percentage.

Developed in collaboration with key partners, these products are claimed to match the performance of standard polyamide yarns while reducing greenhouse gas emissions by 55% at the polymer level.

Indorama is also producing recycled PET yarns and tire cord fabric at its manufacturing site in Kaiping, China.

The yarns and fabrics, it said, are made from 100% recycled PET, highlighting the company’s “circular practices and lower carbon products.”

The certifications, said Indorama, reinforce the group’s commitment to expanding its portfolio of sustainable fibres for the tire and automotive industries, including airbags.
