UV Stabilizer/Absorb Masterbatch

UV stabilizer masterbatch plays a crucial role in prolonging the service life of polymer-based products. They function is to interfere with the free radical formation of the polymer molecules, which typically occurs due to UV exposure. This protection is essential, as it prevents the products from losing their physical and mechanical properties.


In addition, acid-resistant UV stabilizer masterbatches offer superior protection against acidic substances such as pesticides and acid rain. They enhance the product's properties and durability by increasing its resistance to chemical attack, which can otherwise cause premature degradation.


Moreover, when products are exposed to UV radiation, UV absorber masterbatches act as a barrier by selectively absorbing harmful wavelengths. This protects the product's color, texture, and other sensory attributes, and ensures that it remains fresh for longer, thus extending the quality guarantee period.


Note: Loss 20% in strength of products (AATCC TM186-2022 48H, 3% dosage).

What Are The Benefits Of Using Uv Stabilizer/Absorb Masterbatch?

The benefits of using a UV stabilizer/absorb masterbatch include protecting plastic materials from UV radiation, preventing discoloration and degradation, increasing their durability and lifespan, and being environmentally friendly.

What Is The Difference Between UV Stabilizers And UV Absorbers?

UV absorbers and UV stabilizers are both used to protect materials from the damaging effects of ultraviolet (UV) light, but they work in different ways:


UV Absorbers:

Function: These chemicals absorb UV radiation and convert it into harmless heat, which is then dissipated. This prevents UV light from penetrating the material and causing damage.

Application: Often used in plastics, coatings, and textiles to protect them from UV degradation and extend their lifespan.

Example: Benzotriazoles and benzophenones are common UV absorbers.


UV Stabilizers:

Function: UV stabilizers work by either absorbing UV light or by preventing the chemical reactions that UV light can initiate. They help to maintain the material's integrity and appearance over time.

Application: Used in a wide range of products, including polymers, paints, and coatings, to enhance their durability and prevent degradation.

Example: Hindered amine light stabilizers (HALS) are a type of UV stabilizer.

In summary, UV absorbers primarily work by absorbing UV radiation and converting it into heat, while UV stabilizers prevent or slow down the degradation process caused by UV light.
