What that means in practice

685 plus meat wrap — the food-contact variant of the same K70 flexible grade. As with 676H, the approval paperwork is the thing that distinguishes it in practice.

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 685A

• High-K grades are bought for plasticiser uptake, so ask about porosity and how consistently the batch absorbs.
• If the end use is wire, cable or anything food-contact, the approval documentation matters more than the K-value.
• Ask for a batch certificate of analysis rather than the generic datasheet — at this end of the range the batch is what you are buying.
