Grade, concentration or configuration
Which exact polyurethane supplier grade, concentration or configuration is required for this host system? Write the preferred form and leave unknowns blank.
APPLICATION MAPPING
Polyurethane supplier questions mapped along a purchase path
Application language helps a polyurethane supplier understand the process, but it does not prove fitness. The path below turns a use case into purchase fields. Suitability, compliance and plant capability stay unconfirmed until written answers and buyer review exist.
- 01Name the host system: foam, elastomer, coating, adhesive or casting stock.
- 02State form, viscosity window and any aromatic versus aliphatic preference as a question.
- 03List documents and transport constraints for the US destination.
Application matrix used to write the RFQ
| Use context | Specification questions | Evidence still required |
|---|---|---|
| Foam processing | Grade, form, viscosity, moisture, blowing notes | Exact SDS, TDS, CoA and loading trial criteria |
| Elastomer casting | NCO or OH value, pot-life question, color, hardness window | Whether the quote is chemical or finished stock |
| Coatings and adhesives | Solids content, viscosity, flash point if solvent-borne | TDS range, package size and destination freight class |
| Thermoplastic routes | Melt flow, molecular weight, moisture, pellet or chip form | Lot CoA format and any TSCA statement for the exact grade |
Selection trade-offs buyers still decide
Industry files do not publish a scored dispute list, so this matrix records trade-offs rather than a verdict. Aromatic systems may be requested for a known processing history; aliphatic options may be requested for a color or weather question. A higher NCO index can change hardness or pot life; the site does not predict that change. A family SDS is faster to obtain, yet only the exact-product SDS, technical data sheet and certificate of analysis can support a receiving decision.
Limitations that stay on the brief: this desk does not assign a UN number, does not choose a carrier, and does not replace EHS review. Flash point, assay and viscosity are copied from supplier text. If two polyurethane supplier replies use different units, we do not convert them silently. Sample purpose must be written in advance: identity, appearance, assay, compatibility or packaging check.
Open questions before an application quote is compared
Grade and form confirmation
What must the quotation confirm about grade and form so two plants are not priced on different polyol or isocyanate bases?
Documents still missing
Which SDS, TDS, CoA, packaging, transport and unresolved decisions remain after the first reply?
