I'll still keep an eye on it though :-)
Good man! :thumbright:

...I'd still be careful, regardless. The thing that keeps flexible plastics flexible, the so-called "plasticisers" are extremely volatile so they don't last, especially for foam (because of its greater surface area). Unfortunately this component that keeps plastics flexible is also the thing that spells their demise - plasticizers, because they're volatile, will either evaporate over time making the plastic brittle or react with the carrier polymers and break them down, causing the plastic to liquify. These effects can be seen in as little as five years and are especially bad for expanded plastics like PVC foam, styrene foam, Butyrate foam and a host of other compounds.

Over twenty years experience with diverse material types has made me cautious. :lol:
