Light Stabilizers: Guardian UV Absorbers Manufacturers That Protect Materials From UV Damage

Introduction:

In modern industry and daily In life, many materials are exposed to ultraviolet radiation and are susceptible to problems such as color changes, aging and deterioration. Fortunately, light stabilizers as a An important additive that can effectively protect materials from UV damage and prolong their service life.

Main categories:

1, organic light stabilizers: including phenols, benzophenones, aminoketones, etc. They have good light absorption and energy conversion capabilities and are able to absorb and disperse UV radiation.

2. Inorganic light stabilizers: such as metal oxides and metal salts, such as titanium dioxide and zinc oxide. They protect materials by reflecting, scattering and absorbing UV light.

3, Mixed light stabilizer: It is composed of a mixture of organic light stabilizer and inorganic light stabilizer, in order to have both absorption and Advantages of scattering UV rays.

Commonly used light stabilizer models:

UV-123, UV-292, UV-783, UV-327, UV-622, UV-770, UV-944

Features:

1, light absorption Capabilities: Ability to effectively absorb UV radiation and convert it to a lower energy form, reducing damage to materials.

2. Dispersion performance: It can disperse ultraviolet radiation, distribute energy evenly, and slow down the aging process of materials.

3. Free radical capture ability: It can capture free radicals caused by ultraviolet rays and prevent them from oxidizing and degrading materials.

4. Thermal stability: It has high thermal stability and can maintain stable performance at high temperatures.

Physical properties:

1, appearance: powder, granule or liquid

2, solubility: soluble in organic Solvent

Chemical Properties:

The chemical properties of light stabilizers vary depending on the specific compound, but they generally have high thermal stability and chemical inertness, and are not easy to react with other substances. They do not cause adverse effects or side reactions to materials during the application of light stabilizers.

Application field:

Light stabilizers are widely used in various fields, as follows:

1, plastic products: The application of light stabilizers in polymer plastics is very common. They are used to enhance the weather and light resistance of plastic products, preventing color change, deterioration and cracking. The application range of plastic products includes construction materials, auto parts, home appliances, packaging materials, etc.

2, Coatings and paints: Light stabilizers are widely added to coatings and paints to improve their weather resistance and UV resistance performance. This enables the coating to maintain color stability and gloss over time in outdoor environments.

3. Fibers and textiles: In the textile industry, light stabilizers are used in the dyeing and finishing processes of fibers and textiles. They protect the fibers from UV radiation, increasing their durability and color fastness.

4. Automobile industry: Light stabilizers play an important role in automobile manufacturing. They are added to automotive coatings and plastic parts to protect the vehicle from UV radiation, extending the life of its appearance and performance.

5. Medical devices: Light stabilizers are used in medical devices and medical equipment to improve their durability and long-term stability sex. This is critical to avoid the effects of material aging and color changes on medical devices.

Summary:

As an important additive, light stabilizer plays a key role in protecting materials from UV damage. Their choice depends on the type of material, application needs and environmental conditions. Light stabilizers protect the appearance, performance and stability of materials through mechanisms such as absorbing and dispersing UV radiation and trapping free radicals. Plastic products, coatings, fibers, the automotive industry and medical devices are widely used fields of light stabilizers. With the continuous development of science and technology, the research and innovation of light stabilizers will further promote the development of light stabilizers, making them show wider application prospects in more fields. For example, with the rise of renewable energy, the application of light stabilizers in the field of solar cells has also attracted attention. They can help improve the weatherability and stability of solar cells, extending their lifespan.

In addition, the urgent need for environmental protection and sustainable development has also promoted the development of new light stabilizers research and development. Scientists are working to develop more environmentally friendly and efficient light stabilizers to reduce environmental impact and improve material sustainability. This could include biodegradable light stabilizers or novel light stabilizers based on nanomaterials, among others.
