Poetry and truth, how does the hydrolysis-resistant structure come into the polyurethane?

New, soft, chemical-resistant TPU for pneumatics with proportionate biogenic raw material content: Elastic sealing materials contribute significantly to the function, energy efficiency and service life of pneumatic cylinders and valves. These should be correspondingly soft, i.e. in particular smaller than 90 Shore A. Traditionally, thermoplastic polyurethanes compete with soft rubber materials, especially when it comes to meeting high-quality chemical requirements within this genre. Also to enable the important sliding properties required for energy efficiency. Rubber materials have so far been the first choice when it comes to higher temperature requirements and chemical resistance. The TPU grades available on the market are considered to be particularly susceptible to hydrolysis. Konzelmann GmbH has recently started to represent TPU materials that are tailored to pneumatic requirements. In addition to the high-quality physical property profiles, their special properties are primarily in the area of chemical resistance. These new materials are suitable for various types of pneumatic applications and can be flexibly adjusted in terms of Shore hardness. In addition to their exceptional chemical stability, these TPU materials were also certified to have outstanding cold properties. In this lecture, the targeted innovations in the TPU structure in contrast to commercially available TPU will be described and differentiated, thereby providing an explanation for this progress.
