K-value

67

Producer lists it for

Rigid calendering · Flexible calendering · Flexible extrusion

What that means in practice

The odd one in the 622 family: at K67 it is listed for flexible calendering and extrusion as well as rigid, which none of the other 622 grades are. If you need one resin covering both, this is the one Formosa point at.

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 622F

• K65 is the most traded band, which means it is also the band where 'general-purpose PVC' gets used loosely. Get the actual grade name.
• For pipe and conduit work, ask whether the material is prime, near-prime or off-spec, and what the deviation is if it is off-spec.
• Check the packaging and storage history — suspension resin is a powder and it picks up moisture.
