Covestro and Reverdia develop bio-based TPU

摘要

Covestro, formerly Bayer Material-Science, and Reverdia have agreed to jointly develop and promote thermoplastic polyu-rethanes based on renewable raw materials. Covestro will employ Biosuccinium succinic acid from Reverdia for the production of its Desmopan brand TPU for use in a variety of applications, including in the footwear and consumer electronics industries. Coves- tro said it plans to expand its bio-based TPU production in Taiwan to industrial scale. Bio-based Desmopan products are already available in various hardness grades, including 85 Shore A, 95 Shore A and 60 Shore D. According to the manufacturer, they match the good physical properties of conventional grades while also providing a better carbon footprint along the value-added chain. Sim- ulations by Reverdia suggest a roughly 65 % reduction in the carbon impact compared with products produced with petrochemicals. The biomass content of the Desmopan TPU in the aforementioned hardness grades is 65 % (85 Shore A), 52 % (95 Shore A) and 42 % (60 Shore D).
