 Polyurethane urea elastomer

Polyurethane urea elastomer is a type of elastomer that falls under the category of polymers, specifically a subclass of polyurethanes. These materials are known for their excellent mechanical properties, flexibility, and resilience. Here are some key features and characteristics of polyurethane urea elastomers: 1. **Composition**: Polyurethane urea elastomers are formed by the reaction of polyisocyanates (commonly diisocyanates) with polyols and diamines.
