What that means in practice

K80 is far above the range most PVC buyers ever see — well past the K65 general-purpose band and into specialist territory. Very high molecular weight, very demanding to process, bought for mechanical performance in cable, geomembrane and hose.

If K-values are not something you work with daily, our PVC grades and pricing guide explains what they measure and how prime, off-spec, regrind and regranulate differ.

What to check before buying PRIMEX P 300

• High-K grades are bought for plasticiser uptake, so ask about porosity and how consistently the batch absorbs.
• If the end use is wire, cable or anything food-contact, the approval documentation matters more than the K-value.
• Ask for a batch certificate of analysis rather than the generic datasheet — at this end of the range the batch is what you are buying.
