What that means in practice

K57 rigid grade covering film, sheet, bottles and fittings. Medical devices appear on the list, which is worth pausing on — that is an application where batch documentation and consistency matter far more than the headline K-value.

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 180

  • 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.
