What that means in practice

The top of Westlake's published range at K74, IV 1.09. Highest molecular weight, most demanding to process, and the only grade listing case film. If someone offers this for a general-purpose job, they are selling you more resin than the application needs.

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 2110

  • 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.
