How to Prevent Condensation on Tempered Glass | Hunker

How to Prevent Condensation on Tempered Glass | Hunker

Aug 01, 2017 · Condensation is a natural occurrence, but condensation on tempered glass can be prevented. Condensation in the home occurs when there is high humidity in the home. As inside air warms, it retains more moisture, creating humidity. The moisture in the air collects on the coolest surfaces, typically on windows, mirrors or tempered glass.

Thermoplastic Polyurethane Elastomers

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.
