Three Types of Light Stabilizers for Specialty Compounding

When people go outside on sunny and hot days, they usually protect their screen with lotions or clothing. UV rays from the sun can do severe damage to skin when it is not adequately protected. Just as individuals defend themselves from the sun, so must engineers who are constructing plastic products. If the products being created will be used outside or in frequent direct sunlight, you will want to consider plastic additives that will heighten the final product’s UV stabilization. Sunlight will degrade plastics over time. The damage done to plastic is called photodegradation, and it can diminish impact strength, color, tensile strength, and elongation.

When creating products that can withstand the power of the sun, there are three main ways to approach the products:

  1. Ultraviolet absorbers: this light stabilization works by working against chromophores to absorb UV radiation. These absorbers can transform UV radiation into benign infrared radiation/heat that dissipates through the polymer matrix.
  2. Quenchers: these additives transform chromophores in an excited state to ground states. A transfer of energy process does this.
  3. Hindered Amine Light Stabilizers: these stabilizers are frequently referred to by their letters HALS. These stabilizers are considered long-term thermal stabilizers. They work by trapping free radicals that are created during photo-oxidation of plastic.
