My experience with them is they dry out crack and fail. The good ones are used all over the place, you will find them on most duct work these days, inside and outside. You will find them all over solar systems, that sort of thing.
Its sort of like tarps.....the blue ones you find for a couple of bucks each will last about 2 months in the sun, but the expensive ones you find in professional use can last for 10 years or more. Both are made of the same material. The difference is a few chemicals added in processing that blocks UV. This allows oxidation on the surface but not deep enough to destroy the product.
