Meaning
Chemical breakdown of molecules and materials caused by the absorption of light energy, particularly ultraviolet radiation. This aging process is a major consideration in the storage, packaging, and shipping of light-sensitive goods like pharmaceuticals and plastics. It results in structural damage, color changes, and loss of mechanical strength.
Product Longevity
Distribution contracts for outdoor equipment and agricultural packaging often mandate minimum resistance to solar radiation. When photolytic degradation affects these materials prematurely, they can fail, causing leaks, tears, or structural collapses during shipping. Manufacturers utilize light-stabilizing additives to ensure their packaging survives the distribution cycle without loss of strength.
Contractual Indemnity
Retailers frequently require suppliers to guarantee that products will not degrade under standard retail exposure for a specified period. If photolytic degradation reduces the utility or safety of the goods prior to sale, the supplier is obligated to replace the stock or refund the purchase price. This indemnity helps protect the retailer from losses caused by premature material failure.
Exposure Testing
Accelerated weathering tests simulate long-term exposure to sunlight to verify the durability of new material formulations. This testing helps manufacturers evaluate whether their products can safely enter high-radiation markets. It confirms compliance with industry standards before bulk shipments occur.
