Elastollan® is essentially bed from the inter-reb of three components: 1. polyols (long-chain diols) 2. diisocyanates 3. short-chain diols The polyols and the short-chain diols react with the diisocyanates through polyaddition to b linear polyurethane. Flexible segments are created by the reb of the polyol with the diisocyanate. The combination of diisocyanate with short-chain diol produces the rigid component (rigid segment). Fig. 1 shows in diagrammatic b the chain structure of thermoplastic polyurethane. The properties of Elastollan® grades depend on the nature of the raw materials, the reb conditions, and the ratio of the starting materials. The polyols used have a significant influence on certain properties of the thermoplastic polyurethane. Either polyester-based polyols or polyetherbased polyols are used in the production of Elastollan®. The products are distinguished by the following characteristic features: Using polyester polyols: highest mechanical properties highest heat resistance highest resistance to mineral oils Using polyether polyols: highest hydrolysis resistance best low-temperature flexibility resistance to microbiological degradation In addition to the basic components described above, many Elastollan® bulations contain additives to facilitate production and processability. Further additives can also be included to modify specific properties. Such additives include mold release agents, flame retardants, UV-stabilizers and plasticizers as well as glass fibers to increase rigidity.
