TinToll Performance Materials Co., Ltd.
TinToll Performance Materials Co., Ltd.

As a professional UV absorbers supplier, TINTOLL offers the plastics industry a range of hindered benzoates, benzotriazoles, benzoxazinones, benzophenones and triazine as high-performance chemical UV absorbers for polymers that effectively protect adhesives, plastics, coatings and elastomers from the damaging effects of outdoor weathering caused by exposure to UV light. The selection of UV light absorber should consider the characteristics, melting point, volatility, solubility and absorption spectrum of different products.

Types of UV Absorbers Wholesale

UV absorbers are a common way to protect plastics from UV rays. They are classified by chemical classes such as benzotriazoles, benzophenones and triazines. Each category has its own UV absorbing properties. For example, benzophenone and triazine UV absorber tend to absorb more strongly in the short wavelength UV-B region than benzotriazole types. Some common examples of chemical UV absorbers include: Benzophenone, Benzotriazole, Cyanoacrylate, Carbon Black, Hydroxybenzophenone, Hydroxyphenylbenzotriazole, Rutile Titanium Oxide, Oxalanilide. The most commonly used light stabilizers in plastics are hindered amine light stabilizers (HALS).

How to choose UV Absorber?

How to choose UV Absorber?

Chemical UV absorbers are a common way to protect plastics from UV rays. When choosing a UV light absorber additive, you can consider the following factors:

  • Type and model of plastic

  • Processing equipment and conditions

  • Selection and use of other chemicals

UV absorbers wholesale are types of polymer stabilizers and are classified by chemical classes such as benzotriazoles, benzophenones, triazines and oxanilide UV absorber. Each category has its own UV absorbing properties. For example, benzophenone and triazine types tend to absorb more strongly.

The most common UV absorbers for polymers are:

  • Benzotriazoles

  • Benzophenones

  • Organic Nickel Compound

As a leading UV absorbers supplier, TINTOLL UV absorbers wholesale dissipate energy in less damaging forms. UV stabilizers act as scavengers, reducing the reactivity of any free radicals formed inside.


What Materials Does UV Damage?

What Materials Does UV Damage?
  • What Materials Does UV Damage?
    Concrete, Masonry and Stucco

    UV light can damage these materials, but not as quickly as wood.

  • What Materials Does UV Damage?
    Polymer

    UV light can degrade many natural and synthetic polymers, including neoprene, polyvinyl chloride (PVC), and most types of rubber. UV light can cause these materials to fade in color and lose strength. UV light also makes rubber hard and brittle.

  • What Materials Does UV Damage?
    Polypropylene (PP) and Low Density Polyethylene (LDPE)

    These polymers are at increased risk from UV light. UV light can interact with tertiary carbon bonds in its chain structure, and then react with oxygen in the atmosphere.

  • What Materials Does UV Damage?
    PVC Pipe

    UV light can cause slight degradation of the outer shell of PVC pipe. Depending on the color of the pipes, they may start to appear brown or yellow.

    However, not all materials are harmed by UV rays. Metals, ceramics, and some types of glass are often UV resistant. Acrylic is one of the only materials of manufacture that is inherently UV resistant.

How Does UV Light Absorbers Work?

How to choose UV Absorber?

UV absorbers are additives that protect materials from UV damage and degradation.

They work by absorbing UV rays and re-emitting them in a lower energy state. This converts the UV light into harmless heat energy.

Chemical UV absorbers help protect materials from fading, discoloration and other problems.

The amount of UV light absorber required depends on its concentration and the thickness of the surface.

The most important class of UV absorbers wholesale are the hydroxybenzophenones. Triazines are considered the best chemical UV absorbers. It helps protect coatings by absorbing sunlight instead of letting it reach adhesives, plastics, coatings and elastomers.
