Product Description
TODI-based Polyurethane Elastomers For High-temperature Resistance
Product Overview
3,3'-dimethylbiphenyl-4,4'-diyl diisocyanate (TODI) is an aromatic diisocyanate used to enhance the mechanical and chemical properties of polyurethane elastomers. Due to steric hindrance, the reactivity is lower than that of TDI and MDI.
Key Features
- Improves heat resistance and hydrolysis resistance
- Provides superior mechanical properties for harsh conditions
- Enhances physical and chemical properties of polyurethane elastomers
