What that means in practice

K66 covering the building-products set plus medical devices and sealants. One of three grades VESTOLIT publish at K66 — the number will not separate them from P 225-2 or S 6658, and the application lists only partly will.

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 PVC 440

• 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.
