Identity lock
Chemical name, CAS number where known, and whether the buyer will accept an alternative polyol or isocyanate system. Substitutions move to a separate line for approval.
Quote matching
Thermoplastic polyurethane resin quoted on one field set
This matching desk normalizes what each factory must answer for thermoplastic polyurethane resin. It does not rank plants, claim capacity or treat a returned SDS as this site's credential.
| Quote field | Buyer records | Factory confirms |
|---|---|---|
| Grade | Requested hardness or series | Actual grade code and lot window |
| Form | Pellet, chip or other | Cut, pellet size and packaging |
| Melt flow | Process window if known | Measured melt flow on the TDS |
| Color | Natural, clear or specified | Color and any stabilizer system |
Requirement cards used before a thermoplastic polyurethane resin factory is contacted
Use these cards to stop apples-to-oranges replies. A missing field stays visible; it is not filled with a marketing default. Trace metals, moisture and particle size are requested only when the conversion line actually needs them.
Assay lock
Hardness, melt flow, density, moisture and any viscosity limit for liquid intermediates. Molecular weight is recorded only when the buyer already uses that control.
Document lock
SDS, TDS and certificate of analysis format for the quoted product. ISO 9001, GMP, REACH or TSCA evidence is a supplier question, not a site badge.
Lane lock
Quantity unit, requested timing, US destination, UN number if the factory already assigned one, and whether a sample precedes the bulk lot.
Optional budget should name currency and whether it applies per kilogram, per bag or to the whole order. High-end, mid-range, budget or undecided is a buyer preference used to sequence outreach, not a verified factory rating.
SDS, TDS and CoA questions for thermoplastic polyurethane resin replies
Documents describe the quoted grade. They do not authorize Polyurethane Resin Sourcing to operate a plant or to instruct hazardous mixing. Final storage and transport follow the exact SDS, carrier rules and destination law.
- Can one CoA cover the next lot?
- A CoA is lot-specific. Ask whether the next production batch will reissue melt flow, hardness, moisture and residual solvent on the same method.
- If TDS lists a typical melt flow, is that the specification?
- Typical values are not purchase limits unless the factory writes a min/max. Record the gap instead of treating the typical column as a guarantee.
- What if flash point is blank on a pellet grade?
- Leave the field open. Do not copy a flash point from a solvent-borne polyurethane resin. Transport class can change with that number.
- Should TPU pellets and thermoset liquids be compared as one SKU?
- No. Processing route, moisture control and package format are different buyer decisions. Keep them as parallel quotations.
