Understanding vinyl durability

[RONIN]

Hi,

I'm just wondering, if vinyl has a low durability rating of say 2 years what would happen to it after 3, 4 or even 10 years if it was applied behind acrylic. The acrylic blocks UV, so would it still fade? What exactly would happen over time in this scenario since it's well protected.

Thanks

The vinyl would shrink back from the edges of the acrylic quite a bit, also the acrylic blocks some uv, not all, so it would start to crack and yellow at some point. If you are going to the expense and time of reverse mounting on acrylic, spend the extra couple bucks on good vinyl.

Thanks for replying. I'm trying to find some decent mirror gold polyester vinyl that I can mount onto the back of acrylic and laser cut. The ones that I've come across here in the UK have a short durability.

Polyester might be a different story, it doesn't really behave like PVC vinyl in terms of shrinkage/failure etc.

Is mirror gold acrylic an option? (Assuming this exists)

Aslan makes some nice polyester films, they are based in Germany, might be an option

That's good to hear. How do you think it might fair for my use case? What I'm looking to do is apply a UV printed graphic with lots of small transparent section to the back of some clear acrylic. I wanted to then back with gold mirror to fill those sections. Some of the ones I really like are only rated for 2 years though. This is for interior use though.

Almost all of the mirror gold acrylic that I've come across only seems to run in 3mm thickness.

Thanks for the suggestion. I've had a quick glance and some of them look promising.
