The "tailor-made" nature of PU stems from its :
These segments naturally separate into distinct domains, giving PU a unique balance of toughness and extensibility. 3. Industrial Applications Polyurethane
Used in seating for comfort, bumpers for impact resistance, and coatings for corrosion protection and aesthetics. The "tailor-made" nature of PU stems from its
This reaction is often facilitated by catalysts, such as or organometallic compounds (e.g., dibutyltin dilaurate). To create a solid foam, a "blowing agent" is added; commonly, water reacts with isocyanate to produce CO2CO sub 2 gas, which expands the polymer into a cellular structure. 2.
