Elastomers are a separate family of polymers, obtained by cross-linking, which gives them great flexibility. These materials, also known as “TPEs” (thermoplastic elastomers), can have varying proportions of biobased materials depending on the production method.
There are different categories of biobased elastomers depending on their chemical nature: biobased TPU (polyurethane-based), SEBS (ethylene-butene-based), etc. The level of flexibility, abrasion resistance and hardness of these materials varies greatly from one grade to another, which allows them to be used in a wide range of applications (injected or extruded parts for the automotive industry, shoe soles, etc.).
