Frequently Asked Questions
What is the difference between MDI and polyols?
MDI is the isocyanate component and polyols are the hydroxyl component of polyurethane. They react to form foams, elastomers, coatings, adhesives and binders; the choice of polyol sets flexibility, hardness and durability.
Can you supply formulated PU systems as well as raw materials?
Yes. Besides MDI and polyols, PANDA COLLECTIONS sources formulated two-component systems for pipe insulation, cast elastomers, automotive parts, composites, sports surfaces and roads, matched to your process.
Do you show chemical prices on the website?
No. Chemical prices move with feedstock markets and depend on grade, quantity, packaging, Incoterms and destination. Send your requirement for a customised quotation.
