Light Stabilizers

 The addition of light stabilizers for plastics can effectively prevent the photodegradation of polymers. TINTOLL's comprehensive range of solutions including hindered amine light stabilizers (commonly known as HALS), hindered benzoates and UV absorbers can mitigate degradation of plastics exposed to harmful UV radiation and achieve excellent lifetime.

 

The UV light stabilizer can be divided into UV absorbers and hindered amine light stabilizers (HALS):

 

UV absorbers slow down the degradation process by preferentially absorbing harmful UV radiation and dissipating it as heat.

 

Therefore, UV absorbers can effectively protect the contents in packaging products (such as wrapping films or bottles, etc.). UV absorbers also protect other UV-sensitive additives such as pigments and flame retardants.

 

HALS are very effective stabilizers for polymers, especially polyolefins. They do not absorb UV radiation, but inhibit polymer degradation by scavenging free radicals. Remarkable plateaus are achieved at relatively low concentrations. The high efficiency and long life of HALS is due to a cyclic process where HALS are regenerated rather than consumed during stabilization.

 

Therefore, HALS are the most effective additives for light stabilization of polyolefins and they are very effective in high surface area applications such as films and fibers. HALS are also efficient heat UV stabilizers that can prolong the service life of polyolefin products.

 

Selection of an appropriate light stabilization system depends on material type, end application, material thickness, environment of use, interaction with other components of the system, and performance and cost expectations.

 

Ultraviolet absorbers (UVA) and hindered amine light stabilizers (HALS) are often used together to show a synergistic effect to achieve photostabilization of polymeric materials.
