Bio-based TPE compounds are the newest member in the FKuR TPE family.

Customers are more conscious about environmental frirendly solutions, therefore the industry is demanding more sustainable solutions. Consequently FKuR Polymers is able offer thermoplastic elastomer compounds based on bio based sources. Bio-based TPE help to decrease the dependency on limited fossil ressources.

The Terraprene® family includes compounds from hardnesses 20 Shore A to 40 Shore D and up to 90% of bio-based content. In addition they can be easily coloured and for a more natural look they can be filled with organic fibers like wood or cork.

The mechanical and physical properties of our bio-based compounds are close to TPE compounds based on fossil sources.



Terraprene® compounds can be used in various applications for example in soft-touch handles, toys, tools or sports equipment. As a result it can be used a sustainable replacement for PVC as well.
