TPE compounds with over 70% renewable content

1058
  • Physical properties comparable to TPE from fossil based raw materials
  • Suitable for traditional polymer technologies, incl. injection moulding and extrusion
  • Adhesion to other biobased polymers

At this year’s #Fakuma exhibition the Hexpol TPE group, which brings together the ELASTO and Muller Kunststoffe businesses, will launch a new range of TPE compounds based on raw materials from renewable resources. The range, which is called Dryflex Green, is a family of thermoplastic elastomer compounds based on raw materials from renewable resources such as plant and vegetable crops. The range includes several series with amounts of renewable content to over 70% (ASTM D 6866) with hardnesses from 50 to 80 Shore A.

Physical properties comparable to TPE from fossil based raw materials

Dryflex Green TPE compounds display mechanical and physical properties comparable to TPE from fossil based raw materials. They offer flexibility and tensile properties with a soft-touch feel. They can be processed using traditional polymer technologies such as injection moulding and extrusion.

Adhesion to other biobased polymers

Dryflex green TPE compounds give adhesion to biobased polymers, such as PE, for 2K and multi-component applications. In addition, the compounds can be easily coloured. and are fully recyclable.

“We are excited to introduce low hardness TPE products with such high levels of renewable content to the market. We are seeing increasing demands for the polymer industry to look at how we can work with biobased materials and bring new opportunities for sustainability”, commented Klas Dannäs, Global R&D coordinator for Hexpol TPE.

The new TPE compounds could open up sustainability options in the consumer, automotive, packaging, medical and construction markets, according to the company.
