What that means in practice

K85, the highest K-value on this site by some margin and the top of VESTOLIT's suspension range. If you are offered this for a general job, something is wrong — resin this high in molecular weight is bought deliberately, for applications that genuinely need it, and it will not process like ordinary PVC.

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 330

  • 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.
