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.

Fermentors under 60 Gallons | MoreWine

During fermentation, yeast create alcohol and CO2 gas. As the CO2 bubbles up through the wine, a portion gets trapped in the skins and causes them to float on the surface of the wine in a mass called "the cap". The cap actually lifts itself above the surface of the liquid and this causes the volume of must to expand in the tank.
