Grade
Buyer records: Requested value or open
Supplier must answer: Quoted grade and system type
Status: Open until accepted
What a comparable quotation must confirm
Family names are not enough. Similar labels can hide different isocyanate indices, polyol hydroxyl numbers, stabilizer packages or drum fills. The cards below are a buyer checklist, not a product specification issued by this site.
Form
Buyer records: Polyol, isocyanate, prepolymer or system
Supplier must answer: Quoted form and package
Status: Open until accepted
Viscosity
Buyer records: Process window if known
Supplier must answer: TDS range and test temperature
Status: Open until accepted
Melt flow or NCO / OH
Buyer records: Requested index if used
Supplier must answer: Lot method and CoA field
Status: Open until accepted
Color and moisture
Buyer records: Appearance limit if known
Supplier must answer: Written range for the lot
Status: Open until accepted
Packaging and documents
Buyer records: Drum, IBC, tote, SDS TDS CoA
Supplier must answer: Net fill and exact-product files
Status: Open until accepted
No inventory, compliance outcome or savings percentage is implied. Compare product subtotal, packaging, samples, freight and destination charges only when each quotation states those lines.
Application and specification matrix
These cells describe how buyers usually turn a use context into RFQ fields. They are inquiry families, not stocked SKUs and not fitness claims.
Flexible or rigid foam
Specification questions: Grade, form, viscosity, water or blowing-agent notes, moisture
Evidence still required: Exact SDS, TDS, CoA and trial purpose
Elastomer, TPU or casting stock
Specification questions: Molecular weight target, hardness window, color, melt flow if solid, system ratio and pot-life question for casting
Evidence still required: Lot CoA format, package fill, and whether the quote is chemical or finished stock
Coatings and adhesives
Specification questions: Solids content, viscosity, NCO if relevant, flash point if solvent-borne
Evidence still required: Destination freight class and TDS range
Read the procurement brief or open the document guide before expanding the inquiry.
SDS, TDS and CoA questions that keep quotes comparable
-
Which exact polyurethane raw material suppliers grade, concentration or configuration is required?
Write the chemical name, CAS if known, grade, purity or concentration, and whether the request is polyol, isocyanate, prepolymer, system or foam-related chemistry. Leave unknown fields blank rather than guessing.
-
What must the quotation confirm about grade and form?
Ask the proposed plant to state grade, form, viscosity, moisture, color and the certificate-of-analysis fields that will accompany a lot. A related-grade SDS is not evidence for the quoted material.
-
Which SDS, TDS, CoA, packaging, transport and unresolved decisions remain?
List current safety data sheet, technical data sheet, CoA template, UN number if assigned, packaging, and any TSCA or REACH status the buyer still needs the supplier to confirm. Handling follows the exact SDS and carrier rules, not this page.
SAMPLES AND FILES
Define the sample purpose before comparing landed scope
A sample is useful only when the buyer writes what it must confirm: identity, appearance, assay, viscosity, compatibility, processing behavior or packaging. Qualified lab, EHS and formulation staff keep those verdicts; this desk only lines up written answers. After the brief is complete, we coordinate outreach and place responses on one comparison sheet.
