Polymers are widely used in various industries, including construction, automotive, packaging, and many more. However, prolonged exposure to ultraviolet (UV) radiation can cause degradation to polymers, resulting in discoloration, cracking, and reduced mechanical properties. To counteract this, manufacturers use UV absorbers and light stabilizers to enhance the UV resistance of polymers.

Ningbo Inno Pharmchem Co., Ltd. is a leading manufacturer of specialty chemicals, including UV absorbers and light stabilizers. Among their product line is the Light Stabilizer BP-3, also known as 2-Hydroxy-4-methoxyphenyl)phenyl ketone or Benzophenone-3. It is a highly effective UV absorber that provides excellent protection against UV radiation in various polymers.

UV Absorber UV-9 is another product produced by the factory that can be used in combination with BP-3. UV-9 is a highly efficient UV absorber that absorbs UV radiation in the 300-400 nm range. When combined with BP-3, it provides a broader spectrum of UV protection, resulting in enhanced UV resistance and increased lifespan of the polymer.

Light Stabilizer UV-9 is a blend of UV absorber UV-9 and a hindered amine light stabilizer (HALS). HALS is a class of compounds that inhibit the degradation of polymers by scavenging free radicals generated by UV radiation. When combined with UV-9, it provides superior UV resistance and long-term stability to polymers exposed to outdoor weathering.

Benzophenone-3, also known as Sunscreen No. 2, is widely used in personal care products as a UV absorber. Its ability to absorb UV radiation makes it an excellent candidate for use in polymers to enhance their UV resistance. BP-3 is soluble in many organic solvents and has low volatility, making it easy to incorporate into polymer formulations.

2-Hydroxy-4-methoxydiphenyl is another name for BP-3, which is a solid white crystalline powder. It has a melting point of 62-65°C and is stable at room temperature. The recommended dosage of BP-3 varies depending on the polymer and the application. However, typically, it ranges from 0.2% to 2.0%, with higher dosages required for more demanding applications.

4-Methoxy-2-hydroxybenzophenone, also known as 2-Hydroxy-4-methoxybenzophenone, is a related compound to BP-3. It is a highly effective UV absorber and can be used in combination with BP-3 to provide enhanced UV resistance to polymers.

2-Hydroxy-4-methoxy-benzotriazole, also known as Oxybenzone, is another UV absorber commonly used in polymers. However, it has been found to have harmful effects on marine life and is banned in some countries. BP-3 is considered a safer alternative to Oxybenzone, making it an excellent choice for environmentally conscious applications.

Ultraviolet Absorber UV-9 and BP-3 are both highly effective UV absorbers, but they have different absorption spectra. UV-9 absorbs UV radiation in the 300-400 nm range, while BP-3 absorbs in the 280-340 nm range. By using a combination of both, a broader spectrum of UV protection can be achieved, resulting in enhanced UV resistance and increased lifespan of the polymer.

In conclusion, Ningbo Inno Pharmchem Co., Ltd. is a leading manufacturer of specialty chemicals, including UV absorbers and light stabilizers. Their Light Stabilizer BP-3, also known as Benzophenone-3, is a highly effective UV absorber that provides excellent protection against UV radiation in various polymers. When combined with UV absorber UV-9, it provides a broader spectrum of UV protection, resulting in enhanced UV resistance and increased lifespan of the polymer. BP-3 is a safer alternative to Oxybenzone, making it an excellent choice for environmentally conscious applications.
