Learn what TDS, COA, label and application information to send for HDPE, LDPE or LLDPE grade matching with a China supplier.
A technical data sheet helps identify the exact producer, complete grade, test methods and key material properties currently used by the buyer. It gives a more reliable basis for screening a potential PE resin source than a short description such as “film grade,” “pipe grade” or “MFI 1.”
Jiuting Polymers uses the buyer’s current TDS together with the finished application and processing information. We do not claim direct equivalence from one or two numbers, and we do not change the producer or grade name in the document.
A complete PDF is preferred. Clear JPG or PNG files can also be used when the original PDF is unavailable. Please send all pages and make sure the producer, grade and test conditions remain readable.
The test condition matters. An MFI value measured under a different temperature or load cannot be compared directly. Density values and mechanical properties should also be compared using equivalent test bases where possible.
You may cover your current purchase price, supplier salesperson, contract number, purchase-order number and other confidential commercial terms. We do not need those details to begin a technical review. However, hiding the producer, full grade, test conditions or critical specification can make a meaningful comparison impossible.
State the film type, number of layers, thickness, blend, line type, seal requirement, optical target and important dart, tear, puncture or shrink performance.
State the container volume, target weight, filled product, line information, ESCR, drop, stacking and compliance requirements.
State the material class, applicable standard, compound color, SDR or pressure class, project approval and required producer documentation.
Provide the molding or extrusion process, finished part, operating conditions and tests that the material must pass.
A TDS describes typical technical properties for a grade. A COA reports values for a sample or actual production batch. An MSDS or SDS addresses safety, handling and regulatory information. One document cannot replace the others, and each document must correspond to the correct producer and grade.
Send the current TDS, application, required parameters, quantity, destination port and preferred trade term to sales@jiutingpolymers.com. Suggested file name: Producer_Grade_TDS.pdf. We will confirm whether the information is sufficient for a sourcing review.
A clear photograph of the bag label, the exact producer and full grade name, or your internal material specification can start the review. A complete producer TDS in PDF remains the most reliable basis.
Yes. Purchase price, contract numbers and other confidential commercial terms can be covered. The producer, complete grade and test conditions must stay visible, or a meaningful comparison is not possible.
We will tell you exactly which items are missing — usually the test conditions, application details, or quantity and destination information — so you can complete the request in one reply.
