What that means in practice

K70 at IV 1.02, the 5000-series counterpart to 2100. The one-hundredth of a point difference in IV is not something to trade on — treat these two as the same material from a buying point of view.

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 Westlake 5415

• 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.
