UV Absorbers: The Advanced Plastic Protectors

UV, which is short for ultraviolet, is a specific form of electromagnetic radiation. 

UV is present in many areas, including the earth’s sunlight, and can also be generated artificially by man, in a non-natural process.

Like other forms of radiation, UV can be harmful to the things that it impacts – including living objects. For example, UV light is the reason we humans get a sunburn. 

UV is also used in a variety of sterilization applications, in order to destroy viruses and bacteria.

UV light can also damage non-living objects, especially surfaces of many kinds. This damage is called UV degradation. This degradation can harm surface color and can even change its texture. This characteristic has prompted scientists to formulate UV absorbers for a variety of applications. Perhaps the most famous UV blocker is the sunscreen lotion that we rub on our skin when we go to the beach. But there are other kinds of UV absorbers – including UV absorbers for plastics.

The UV absorber additive: a general definition

UV light can harm plastic. It can ruin its color, change its appearance and even impact the plastic material and change its properties. That’s why UV stabilizer for plastics is so important.

The UV stabilizer is an additive. In fact, it is a very common additive for plastics in a wide range of industries. This is mainly because many plastic products – from packaging to greenhouse and field products – are often exposed to sunlight, which carries UV rays.

The UV stabilizer for plastics is added to the raw polymer during the plastic product’s manufacturing process. By absorbing and eventually scattering UV radiation, UV absorbers protect it from this specific form of electromagnetic radiation – and prolong its life cycle.

Another industry greatly impacted by UV additives for plastic is building and construction. Many pipes and fittings that protrude from below the ground and are exposed to sunlight are in danger of UV degradation. When these plastic products contain UV stabilizing additives, then their properties are aptly protected. Polycarbonate sheets – commonly known as PC sheets – are another common product that is prone to degradation. Fortunately, our UV stabilizer protects the polycarbonate, which is a transparent polymer, and prevents many negative reactions, such as a yellowing hue, ruptures, and more.
