Polymeric MDI

1-Product Name: POLYMERIC MDI 

2-Chemical Name: POLYMETHYLENE POLYPHENYL POLYISOCYANATE

Specification:

This product can be used for the production of rigid insulation foams by molding, spraying, and frothing. It is also used for rigid and semi-flexible integral skin foams, adhesives, sealants, elastomers, and high-resiliency flexible foams. In low catalyzed rigid urethane formulations, the foam rise time can be lengthened by 20-30%. The slower reactivity can be advantageous in applications such as large rigid foam panels or molded flexible foams
