Biopolymers are partly or completely composed of NAWAROH®, renewable raw materials or other raw materials shown in the diagram. A further distinction is made between biodegradable and resistant materials. Biopolymers are increasingly used as so-called “drop in” solutions, i.e. a replacement of the known engineering plastics by Biopolymers takes place. With regard to ethics the variant of extraction from food is not only discussed at the level of science. Just as with Thermoplastics, a distinction is made between applications in technical sectors or in consumer applications or even in the use of packaging. The performance profiles differ in the key areas as resistance, impact strength, temperature behaviour, electrical characteristics etc. The prices per kg also deviate significantly.
