It's usually said that Natural Latex material you buy degrades over time which I assume if treated well is mainly from being exposed to oxygen in the air? Even with a silicone based polish coat on the material all the time.
At typical temps & moisture levels, is it oxygen that primarily degrades Latex? Or is it more complicated with wear & tear & molecules breaking down?
What time scales until it starts to noticeable degrade? If the material is thicker does it take alot longer?
As for acrylic plastics that store things like cd's, do they noticeable degrade in our life time from the air?
