Ultraviolet (UV) radiation from the sun and other light sources, such as fluorescent lighting, are harmful to polymer properties. Finished plastic parts exposed to direct or indirect sunlight can exhibit surface chalking as the polymer becomes oxidized and can lose physical properties, becoming brittle to the point of no longer being suitable for their original use. UV light also speeds up the fading of plastic colorants.
The extent and rate of this degradation are influenced by various parameters, such as climatic conditions, the thickness of the part, polymer type, or the presence of other additives.
The use of UV stabilizer additives can inhibit or absorb the harmful UV radiation that causes polymer degradation. There are two primary types of stabilizers used today: UV absorbers and Hindered Amine Light Stabilizers (HALS).
It is important to know the specifics of the end-use environment, polymer base, and processing conditions to design the most effective UV stabilization package to meet the performance expectations.
Samtone Industries offers a wide range of Samtone UV stabilizer masterbatches. These cover applications in agriculture, industrial, and food packaging for polymers such as PE, PP, EVA, PLA, PC, PMMA, ABS, and range from standard grades to highly performing stabilizer packages based on the latest generation of HALS stabilizers.
The expertise developed by Samtone Industries in this field allows us to provide you with tailor-made and cost-effective masterbatch solutions for your specific needs. Below is the wide range of UV masterbatch applications.
