Quick Answer: What Happens To Plastic In The Sun?

Does PVC degrade in sunlight?

When exposed to direct sunlight, CPVC and PVC shows “UV degradation”, but only between 0.001 to 0.003 inches.

Once pipes are removed from the direct exposure, the ultraviolet rays no longer affect them.

Long-term sunlight exposure can decrease the CPVC and PVC’s impact strength and resistance..
