PVC foam plasticizer migration issue
PVC foam plasticizer migration issue
(OP)
Howdy all,
I am considering spec'ing a flexible PVC foam with an acrylic pressure-sensitive adhesive backing. This material would be stuck down to a plasticizer-sensitive substrate. Do you think that the plasticizers in the PVC foam could migrate through the PSA and harm the substrate?
I've considered using foams that don't have plasticizers (silicone, urethane), but I would prefer to use PVC foam if possible.

The PVC plasticises will always migrate to some extent if present, but some plasticises are much more resistant than others.
If your PVC supplier will provide you with the information as to the types of plasticises, you can treat the adhesive with a concentrated application then you can assess the risk.
