Plastic products tend to discolor and degrade in presence of light. The UV radiation has the power to break the chemical bonds within the polymer, and this process is termed as photodegradation. This might finally result in changes in colour, cracking, loss of polymer’s physical properties, and chalking. So, to keep these damaging effects of UV rays at bay, UV stabilizers for plastics play the vital role. UV stabilizer additives will lower the degradation level related to harmful UV rays.
HALS can be noted to be the most effective version of UV stabilizers for polymers against any light-related degradation of polymers. By using this stabilizer at the lowest concentrations, you can increase the stabilization levels in polymers. Longer life and high retention levels are achieved by using different type of monomeric & polymeric HALS. Here, the HALS can be seen regenerated and not consumed during the stabilization process.
This regeneration property makes HALS extremely cost-effective in the long run despite UV stabilizer price, which varies based on formulation, concentration, and application. Especially for manufacturers looking to stabilize outdoor-use plastics like UV stabilizer for PP (polypropylene) or UV stabilizer for polyethylene, this becomes an essential consideration.
UV light will be within the range of 280 to 400nm, and you can find visible light within 400 to 800nm. Later the UV light gets subdivided under UV-A and UV-B. The intensity of sunlight along with its composition is subject to vary as per atmospheric effects, latitude, and more. So the designing of the UV stabilizer masterbatches is very critical based on the retention requirements and the area /location of use. Some of the other points to be taken care of are the other ingredients added along with stabilizers like colorants, flame retardants, Antioxidants etc. Application information like food contact, pesticide use etc. also play a vital role.
Choosing the right UV stabilizer for polyethylene or UV stabilizer for PP requires careful evaluation of not just end-use conditions, but also compatibility with other masterbatches in the system—such as engineering polymer masterbatches or engineering polymer color masterbatch, depending on the resin type.
AddKan UV stabilizer additive Masterbatches are produced considering the above points with ultimate consistency to ensure the end product performance. But proper information like UV ray intensity (based on geographical location), article’s thickness, exposure time, and life expectancy are important to decide the type/types of additives & the final dosage. In many cases combination of additives gives synergistic effect.

Yes, UV stabilizer price depends on the type of stabilizer used, the polymer it is meant for, the concentration required, and the performance life expected.
HALS-based UV stabilizer for PP and UV stabilizer for polyethylene are highly recommended for outdoor use due to their durability, regeneration property, and long-lasting effect.
