Product Description
Product Overview
Lupranate® M20S is a polymeric MDI (methylene diphenyl diisocyanate) with a functionality of approximately 2.7, designed as Part B in two-component polyurethane systems for durable industrial applications.
Applications
- Rigid insulation foams via molding, spraying, and frothing
- Rigid and semi-flexible integral skin foams
- Adhesives, sealants, and elastomers
- High-resiliency flexible foams
In low-catalyzed rigid urethane formulations, Lupranate M20S extends foam rise time by 20-30%, providing advantages for large rigid foam panels and molded flexible foams.
