UV radiation is a primary cause of degradation in plastics, which can lead to discoloration, brittleness, and loss of strength and flexibility. Therefore, it is crucial to add UV stabilizers to plastic products to protect them from the harmful effects of UV radiation. Among the various UV stabilizers available in the market, Light Stabilizer UV-3638 stands out as one of the best. Manufactured by Ningbo Inno Pharmchem Co., Ltd., this product offers optimum protection to plastic materials against UV radiation.

Light Stabilizer UV-3638, also known as Cytec Cyasorb UV 3638, Cytec 3638, Cyasorb UV 3638, or UV Absorber UV-3638, is a highly effective UV stabilizer that belongs to the class of benzoxazinone derivatives. Its chemical name is 2,2-(1,4-Phenylene)bis-4H-3,1-benzoxazin-4-one, and its molecular formula is C30H18N2O4. The product is available in the form of a yellow powder, which is soluble in organic solvents such as chloroform, dichloromethane, and ethyl acetate.

One of the unique features of Light Stabilizer UV-3638 is its broad-spectrum UV absorption capacity. It can absorb UV radiation in the range of 280-400 nm, which includes both UVA and UVB rays. This wide absorption range ensures that the plastic products protected with Light Stabilizer UV-3638 are shielded against the entire UV spectrum, providing maximum protection against UV-induced degradation.

Another advantage of using Light Stabilizer UV-3638 is its excellent compatibility with various polymers, including polyolefins, styrenics, polyesters, and engineering plastics. It can be used in a wide range of applications, such as films, fibers, injection-molded parts, and extruded profiles. The product is also heat-stable, which means it can withstand high temperatures during processing without losing its effectiveness.

Light Stabilizer UV-3638 works by absorbing the UV radiation and converting it into harmless heat energy, thus preventing the radiation from reaching the polymer matrix. This process, known as photodegradation, is the primary mechanism of UV-induced polymer degradation. By blocking the UV radiation, Light Stabilizer UV-3638 prevents photodegradation and extends the lifespan of plastic products.

In addition to its UV stabilization properties, Light Stabilizer UV-3638 also offers other benefits, such as improved weatherability, enhanced color retention, and increased gloss. These properties make it an ideal choice for outdoor applications, where plastic products are exposed to harsh weather conditions, such as sunlight, rain, and wind.

As a leading manufacturer of UV stabilizers, Ningbo Inno Pharmchem Co., Ltd. has extensive experience in producing high-quality products that meet the needs of various industries. The company's state-of-the-art manufacturing facility ensures that the products are manufactured under strict quality control standards, ensuring consistent quality and performance.

In conclusion, Light Stabilizer UV-3638 is an excellent UV stabilizer that provides optimum protection to plastic materials against UV radiation. Its broad-spectrum UV absorption capacity, compatibility with various polymers, heat stability, and other benefits make it an ideal choice for a wide range of applications. As a trusted supplier of UV stabilizers, Ningbo Inno Pharmchem Co., Ltd. ensures that customers receive the best product quality and performance, making Light Stabilizer UV-3638 the manufacturer's best UV stabilizer.
