APPLICATION TO RFQ
Polymers supplier requirements mapped from the process site
Compounding, molding, film and converting plants often describe a job first and a chemistry second. This page turns that job into purchase fields: resin family, melt flow window, required documents, quantity rhythm and destination limits. Suitability is not decided here; the RFQ only records what the buyer already knows and what factories must still confirm.
- 01 Compounding fields
- 02 Molding windows
- 03 Film and converting notes
- 04 Destination limits
USE MATRIX
Application rows that change polymers supplier fields without claiming a qualified part
| Use context | Fields to add on the RFQ | Still open until quoted |
|---|---|---|
| Rigid molding | Resin family, melt flow window, color, pellet form | Impact values, shrinkage, factory process capability |
| Flexible compounds | Hardness target if known, plasticizer question, color | Compression set, aging data, additive package |
| Film and converting | Density, optical need, roll versus pellet | Gel count, residual monomer, line yield |
| Distributor refill | Repeat cadence, 25 kg bag versus gaylord, dock height | Minimum run, ship window, bilingual labels |
Selection trade-off: one polymer family versus several grades
Buyers sometimes want one polymers supplier grade to cover molding, film and compounding. Factories may instead quote different melt-flow windows, densities or additive packages. The worksheet keeps those alternatives on separate lines. Choosing one grade for convenience versus several grades for process fit is a buyer decision after documents arrive; this site does not pick a winner.
Selection trade-off: melt-flow window versus method temperature
A melt-flow number without load, temperature and method name is not comparable to a buyer’s process window. Ask the factory to name the method. Viscosity for liquid resins follows the same rule. This is a measurement alignment issue, not a claim that the quoted resin will run on a specific press.
Selection trade-off: lowest unit price versus delivered scope
A bag price that excludes hazardous freight, pallets or sample testing is not comparable to a delivered lot. Compare product subtotal, packaging, samples, testing, freight, duties and destination charges only when each quotation states them. No lowest-price outcome is promised.
Limitations that stay visible: this page cannot set a tool design, cannot classify a shipment, and cannot treat a related SDS as evidence for another concentration. Flash point, UN number and packing group must come from the quoted product file. Moisture, particle size and molecular weight stay open until the CoA format is confirmed.
APPLICATION DOCUMENTS
Files that application owners usually request before a polymer lot is compared
- Safety data sheet matching the quoted concentration and form.
- Technical data sheet with method names for melt flow, viscosity or density if those limits exist.
- Certificate of analysis columns the receiving lab will actually check, including assay, moisture and color where relevant.
- Transport classification and package confirmation for the US destination.
- Sample protocol: what the sample is intended to confirm and who signs pass/fail.
A public resin-family page can only help label the questions. TSCA or REACH status is asked of the named plant and bound to that SKU. Solids or active content apply only to a liquid resin or concentrate, never as a default on dry pellets.
Translate the process site into a polymers supplier brief
Name the molding or film job, the repeating quantity, the receiving dock limit and which SDS or CoA columns are still blank. Outreach follows that process map, not a family catalog page.
