Thermoplastic Polyurethane Elastomers

Elastollan® is essentially formed from the inter-reaction 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 form linear polyurethane. Flexible segments are created by the reaction of the polyol with the diisocyanate.
