Now that you understand some negative effects of light degradation on polymers, let’s discuss the solutions to these problems. These by-products then escape into the environment and accumulate in animals and humans. The degradation of some polymers is often characterized by the release of harmful by-products. This is because of the polymers dispersing the incident light rays instead of letting them through. Transparent polymers lose their transparency on exposure to light degradation. And when this happens, the polymer becomes weaker and it’s only a matter of time before a little amount of stress breaks it. This is a consequence of the breaking of long molecular chains into shorter bits. Light degradation causes the molecular weight of the polymers to reduce. UV degradation leads to the loss of those mechanical properties that once enabled the polymers to do their jobs. These are the various ways light and UV degradation can affect polymers: And for an unfortunate handful, they experience both. Some other polymers become weak in their molecular structures and break easily. Some polymers only get affected in their looks and their coloration. The effects of UV degradation on polymers range from physical to chemical. view of a bottom-up How UV Degradation Affects Polymers Each part talks about everything from what light stabilizers are, their types, the polymers they are most compatible with, and how to ship the polymer additives.īut before we go further, let’s have you understand the effects of light and UV degradation on polymers. And to ensure you don’t get lost somewhere before the end, we have divided this guide into four parts. This guide discusses light and UV stabilizers exhaustively. This is why we use light and UV stabilizers. But there are ways of protecting these polymers from degradation factors. And so polymers that are used outdoors are at constant risk of degradation through these three unavoidable factors. So do the light and heat from the same sunlight. The UV rays that come from the sun bear nothing but evil tidings for polymers.
