TPU / Desmopan
Product Description:
Covestro's thermoplastic polyurethanes are characterized by a wide range of properties. Desmopan® has a linear polymerization chain consisting of alternating flexible and rigid segments. The flexible segment has a low glass transition temperature, while the crystalline segment exhibits a high melting point. Modification of these phases makes it possible to change properties such as hardness, strength, stiffness, elasticity and cold elasticity. The material is also inherently flexible and does not require the use of plasticizers.
In addition, our Desmopan® EC range offers exciting new possibilities for improving sustainability. Depending on the hardness of the product, up to 60% of the carbon content* of the Desmopan® EC series comes from biomass. Compared to fossil-based TPUs, the carbon footprint can be reduced by more than 20%. In addition to offering the same quality and high performance product properties as other Desmopan® products, Desmopan® EC has excellent resistance to oils, greases and solvents, as well as weathering and high energy radiation resistance.
*Bio-based content determined according to ASTM-D6866 standard
