What that means in practice
K57, IV 0.69 — effectively the 2000-series twin of 5265, with an identical application list. If both are offered, the difference is not in the published figures, so ask the seller what they actually have.
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 2070
- Confirm the K-value on the batch, not just the grade name — low-K grades are chosen for flow, and a drift upward changes how it fills.
- Ask what it was intended for. Low-K resin sold as general-purpose will disappoint in an application that needed mechanical strength.
- For anything moulded, ask about colour consistency and regrind content if it is not prime.
