Antioxidant UV stabilizer additives guide

1. Polymer degradation and stabilization

Autoxidation may be initiated by heat, high energy radiation such as ultraviolet light, mechanical stress, or through reaction with other impurities. Antioxidant delay the formation of free radical species and hydroperoxides in polymers both during storage and conversion. UV absorbers and hindered amine stabilizers protect polymers from UV light degradation.

what are antioxidants?

Antioxidants are used for anti-oxidising function. Vitamins have anti-oxidation functions. when it comes to industry, certain antioxidant work for the same purpose.  Antioxidant as used to improve polymers’ high-temperature stability and shelf-life.

Polymer antioxidants including hindered phenolic, amine which belongs to the primary antioxidant,  phosphite, thioesters which belongs to the auxiliary group, and blends of a primary with an auxiliary. Typical antioxidant types as follows.

what’s antioxidants’ application and how to choose?

antioxidants are widely used in plastics, rubber, fiber, coatings, polymers and adhesives industry. basically, antioxidants are used in every polymer processing. Effective use temperatures for antioxidants as the photo below.

3. UV stabilizers

what is UV stabilizer?

Except for the heat, products are exposed to light, no matter its direct sunlight or light from the lamp. Thus UV protection for polymers is vital,  otherwise, the products could cracking,  yellowing and delamination due to UV light degradation.

UV stabilizer contains two groups, the first is Ultraviolet Light Absorbers, also known as UVA or UV absorber, the second group is Hindered Amine Light Stabilizers which known as HALS or light stabilizers. They are used individually or as blends. UV absorber filters harmful UV light and helps prevent color change and delamination of coatings, adhesives, and sealants.  Types of UV absorber include benzophenone(UV 531), benzotriazole(UV P, 234, 326, 327, 328, 329) and hydroxyphenyl-triazine which market share is decreasing as the former two increases.

Light Stabilizers trap free radicals once they are formed and are effective in retaining surface properties such as gloss and prevent cracking and chalking of paints. The combination of these two families is highly synergistic.  Hindered amine light stabilizer reaction mode as photo below.

what is UV stabilizers’ application and which to choose?

UV stabilizers are used in plastics, rubber, coatings, paint, adhesive, polymer, and different resins.
