TPU Based on Carbon Dioxide Technology
Covestro A.G. has incorporated polycarbonate polyols made with carbon dioxide into its Desmopan thermoplastic polyurethane (TPU) product range. The company said that this is the first time CO technology
2 is being used in a TPU. The Company claims that the new TPU products left a lower carbon footprint than conventional ones, and helped close the carbon cycle. This also conserves fossil resources and, unlike many bio-based materials, would not compete with food production.
Desmopan 37385A is designed for extrusion, and is also suitable for injection molding. Its physical properties include Shore A 85 hardness, 36 MPa tensile strength and 660 percent elongation at break. With this the company also plans to expand the new TPU series by developing another Desmopan CO grade with
Shore A 95 hardness.
