How does the K-value on the row affect PVC processing?

The K-value indicates the average molecular weight of the Polyvinyl Chloride (PVC) resin. A higher K-value means longer polymer chains, which results in higher viscosity and greater mechanical strength. You must select a K-value that matches your extrusion or injection molding temperature profile. If the K-value is too high for your machine, the material will not melt properly. If it is too low, the final product will lack durability.

What happens if the PVC moisture content exceeds the spec?

Excess moisture in the resin causes hydrolysis during high-temperature processing. This creates voids, silver streaks, or surface defects in the final product. The seller states the moisture limit on the row. You must ensure the drying process before extrusion removes this water. Ignoring the moisture spec leads to wasted material and machine downtime.

Why do I need a fresh Certificate of Analysis for this batch?

The Certificate of Analysis confirms the specific batch meets the destination chemical regulations. It lists the exact heavy metal content and residual monomer levels. These values can vary between production runs even for the same grade. Customs will reject the shipment if the certificate does not match the physical goods. Always request this document before paying the deposit.

How does the posting date impact the reliability of the quote?

The listing shows when the seller last updated their price data. Vinyl chloride monomer prices fluctuate based on oil and gas markets. An old row may reflect costs from weeks ago. The factory will likely reject an order based on an outdated price. Check the date to ensure the quote is current before sending an enquiry.

Who pays for inland haulage of PVC from the factory?

This depends on the incoterm stated in the listing. If the price is EXW, you pay for the truck from the plant to the port. If the price is FOB, the seller covers this inland transport. PVC is dense and heavy, so trucking costs are significant. Misunderstanding the incoterm leads to unexpected landed cost increases.

What distinguishes rigid PVC from flexible PVC on this page?

Rigid PVC contains no plasticizers and is used for pipes and profiles. Flexible PVC includes plasticizers to increase bendability. The row should state the plasticizer content or the intended application. Confusing the two leads to processing errors and failed products. Verify the formulation type before comparing prices.

Why is the unit of sale critical for PVC pricing?

PVC is often sold by the metric ton or by the bag. The price per unit changes based on the packaging size and handling requirements. A quote per bag may look cheaper but cost more per kilogram. Always convert all quotes to a standard weight unit. This ensures you are comparing the actual material cost, not just the packaging format.
