Application:

Polymethylene polyphenyl polyisocyanate can be widely utilized in the production of stiff PU foam heat-insulating products; likewise made use of in isocyanurate foam, paints, adhesives, structural foam, mobile important skin foam, automobile bumper and also interior parts, high-resilience foam and also artificial timber, etc.

As a result of its special composition framework, polymethylene polyphenyl polyisocyanate can offer much better flowability. It is, consequently, especially appropriate for the production which call for strict flowability of systems.

It is used along with polyols to create rigid polyurethanes foam.

Security and Reactivity:

Chemical stability: Polymerises at around 200 ° C with evolution of CO2.

Possibility of harmful reactions: Exothermic response with amines and alcohols; responds with water developing carbon dioxide; in closed containers, threat of bursting owing to enhance of pressure.
