7 Jan 2019
UV Protection: Light stabilizers effectively absorb or neutralize UV radiation to prevent it from damaging chemical bonds in materials.
Enhanced Durability: They significantly extend product life by reducing photodegradation, discoloration and loss of mechanical properties.
Thermal Stability: Many light stabilizers also provide thermal stability, ensuring the material can withstand high temperatures without degrading.
Compatibility: They are compatible with a variety of polymers and other materials, making them suitable for a variety of applications.
Principles of Action
Ultraviolet Absorbers (UVA): These compounds absorb harmful UV radiation and dissipate it as low-level heat, preventing UV rays from reaching and damaging materials.
Hindered Amine Light Stabilizer (HALS): HALS does not absorb ultraviolet light, but works by scavenging free radicals formed during photo-oxidation. This prevents a chain reaction of degradation, thus stabilizing the material.
Light stabilizers are incorporated into the material during the manufacturing process. The concentration and type of stabilizer used depends on the specific requirements of the application, such as expected UV exposure, type of polymer, and desired service life of the product.
Plastics and Polymers: Used in packaging, automotive parts, agricultural films, and construction materials to prevent UV-induced degradation.
Coatings and Paints: Used in automotive coatings, industrial coatings, and exterior coatings to maintain color and integrity over the long term.
Textiles: Incorporated into fibers and fabrics to protect against UV damage, which can cause materials to fade and weaken.
Adhesives and Sealants: Used to ensure long-term performance and durability when exposed to sunlight.
Cosmetic: Added to sunscreen and other skin care products to protect skin from harmful UV radiation.
Light stabilizers are essential to improve the durability and performance of materials exposed to UV radiation. By understanding their properties, principles of action and applications, industries can effectively utilize these additives to produce high-quality products that last longer.
