France-based chemical company Arkema SA has extended its range of Pebax thermoplastic elastomers with a grade made entirely from renewable resources.

Colombes-based Arkema says it created Pebax Rnew100 by combining a bio-sourced polyol with castor oil chemistry. The material is light-weight and resistant to heat, ultra-violet ageing and flexural and tensile stress, according to the firm.

Pebax Rnew100 is designed for use in applications in eco-design programs, particularly in the auto, electronics and sports equipment sectors.

Other grades in the Pebax range have a bio material content of between 20 and 95 percent.
