The polyol used in Covest's innovative TPU helps to reduce the carbon footprint of the material.
Covestro launched the first TPU based on carbon dioxide technology. The company first developed a carbon polyether carbonate based on carbon dioxide technology, which is currently being marketed.
With the recent launch of the Desmopan 37385A series, the company offers the first representative of the new range of TPUs, which are based on CO2 technology and contain new polyether carbonate polyols.
Compared to traditional TPU materials, the new TPU products have a lower carbon footprint and help to shorten the carbon cycle. They also protect fossil resources. Unlike many biobased materials, they do not compete with food production. Covestro's TPU Expert Georg Fuchte pointed out, 'With the new TPU, our customers can reduce the carbon footprint of their products and be able to play a pioneering role in sustainability compared to their competitors. This is especially true for companies in the consumer goods industry, which usually Production of products with a short service life. '
Desmopan 37385A has a Shore hardness of 85 A and is reported to have mechanical properties at least comparable to conventional TPU grades of similar hardness and, in some cases, superior to conventional TPUs of similar hardness. For example, its tensile strength is 36 MPa (5221.3671 psi) with an elongation at break of 660 %. Although designed for extrusion, it is also suitable for injection molding. According to Fuchte, the application covers the typical end use of traditional TPU, its hardness and The range of applications ranges from soles and uppers to sportswear, handles, knobs and sensitive electronics packaging.
Covestro plans to expand the new TPU product range with variants of different hardness. For example, a product with a Shore hardness of 95A, which melts and solidifies rapidly during processing, has been well developed. 'So our goal is to The product is used in applications where short-cycle economic production is particularly important,' Fuchte explained.
