What that means in practice

At K56 this is one of the lowest-molecular-weight grades Formosa list, which is what makes it flow well enough for injection moulding and blow moulding — processes where a higher-K resin would simply not fill. The trade-off is mechanical performance, so it is not a pipe resin.

If K-values are not something you work with daily, our PVC grades and pricing guide explains what the number is measuring and how rigid, flexible, resin, compound and regrind differ.

What to check before buying Formolon 608

  • 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.
