Product Description
Product Overview
Lupranate® M20S is a polymeric MDI isocyanate with approximately 2.7 functionality, specifically engineered for high-performance rigid foam insulation applications. This versatile chemical is ideal for manufacturing rigid insulation foams through various methods including molding, spraying, and frothing processes.
Key Applications
- Rigid insulation foams (molded, sprayed, frothed)
- Rigid and semi-flexible integral skin foams
- Adhesives, sealants, and elastomers
- High-resiliency flexible foams
