There are numerous
factors that adversely affect the quality of the polymers over a period of
time. After a usage of a product for a given
period of time, the quality of the polymers starts affecting. Normal wear and
tear are usually
seen in every product but apart
from this, there are numerous properties that get affected due to the
environmental exposure and related factors.
The environmental factors
that leave a great impact on the properties of a polymer are solar radiation,
moisture, rain, acid, humidity ultraviolet radiations, etc. Solar radiation
greatly affects the chemical bond of the materials due to the reaction that are
initiated due to the absorption of sunlight by the material. Ultraviolet is
another major component of the sunlight that breaks down chemical bonding of
the material. This degradation is popularly known as the UV degradation of the
polymers. Moreover, different temperatures also affect the quality of the
material in various manners. When the
polymers are exposed to different temperatures, the breaking in the chemical
bonding will be accelerated. At high temperatures, the molecules of the
polymers move at a fast rate,
and this will enhance the photochemical
process that result in degradation of the polymers. Moisture in the form of dew
drops, rain, moisture, frost, and humidity, are usually absorbed by the synthetic
materials that negatively affect the polymers and degrade the quality of the
materials.
