PolyurethaneRaw answers the questions that come up when polyurethane raw materials are specified, bought and processed: which polyol for which foam, what the NCO content on a certificate means, why a catalyst change can collapse a foam, and what to ask a supplier before the first trial. It is written in plain technical English, without a sales pitch on every line.
01What The Site Covers
- Raw material families: polyols, isocyanates and prepolymers and additives, with grades, typical values and handling.
- Applications: how the raw materials combine in rigid and flexible foam, footwear, coatings, adhesives, sealants, elastomers and binders, in the application guide.
- Buying and quality: incoming inspection, supplier comparison and total cost, in the articles.
02Who It Is Written For
Purchasing managers comparing offers, formulation chemists checking a grade, production engineers investigating a defect and students who need a reliable overview. The guides assume a basic knowledge of chemistry but explain every abbreviation the first time it appears.
03How The Content Is Written
- Typical values are typical. Ranges for NCO content, hydroxyl value, viscosity, dosage or isocyanate index are general industry values and are labelled as such. They are not product specifications. For a specific grade, use the supplier's technical data sheet and the certificate of analysis for the batch.
- Company facts are sourced. Where a supplier is named as an example, its figures come from that company's own published pages. Nothing on this site invents customer names, prices or test results.
- Regulation is cited. Statements about regulation, such as the EU training requirement for diisocyanates, link to the official text or to the industry association that explains it.
- Pages are dated. Each guide and article shows when it was published and last updated, and is reviewed when standards, regulation or common practice change.
04Photography
The photographs illustrate typical applications and laboratory work. They do not show any particular company's products or premises.
05Technical Review
The technical content is reviewed by Pluskim Kimya, a polyurethane systems house in Istanbul. Where Pluskim products are mentioned in the guides, they appear as one example of a supplier, next to the independent sources listed on each page.
06Updates And Corrections
Pages are checked against current standards, regulation and the cited sources, and every correction changes the page's update date. The site does not publish a contact form; for buying, the supplier checklist explains what to ask a producer.
07About This Domain
