If it relys on a plastisizer for retaining flexibility, the chemical
will eventualy leach out into the substrait and the resin will become
brittle and subject to cracking. The length of time for this is
dependent on what the resin is ,what plastisizer chemicals are used,
the environment it is exposed to and so on. Think plastic dashboards
on automobiles and what happens to them with sunlight over time.
(Might take longer in UK ?? :-))
