Polyurethane insights
Practical, jargon-light writing on the chemistry we trade — polyols, TDI, MDI and the additives that tune a formulation — plus the logistics that move them.
The two isocyanates behind nearly all polyurethane. What separates TDI from MDI, and a practical way to pick the right one for your product.
Polyols are the backbone of polyurethane. A clear guide to polyether vs polyester polyols, OH value, functionality and how they shape the final foam.
ChemistryCatalysts control the speed and balance of the polyurethane reaction. How amine and tin catalysts work, and why most foams use both.
ApplicationsSame chemistry, very different materials. What makes a polyurethane foam soft or hard, and which raw materials drive each.
LogisticsFOB, CIF, CFR, DAP — what each Incoterm actually shifts between buyer and seller, and how to read a quote before you sign.
