Plastic Additives

UV protection of plastics
Global solar irradiance

1 kLy = 41.84 MJ / m?, Data provided by the Ozone P

rocessing Team at the NASA Goddard Space Flight Center.

This map depicts the global variation of average irradiation energy reaching the earth’s surface. UV irradiation energy is responsible for light induced deterioration of plastics and other materials. Therefore, light stabilizer formulations must consider the global location where the ?nal article is used and its expected service life.

Absorption characteristics of UV absorbers
Individual polymers are affected by different wavelengths. Choosing the most effective light stabilizer for a given substrate depends upon matching the right UV absorber with the susceptible wavelength range of the polymer.
