The ultraviolet absorber BP-6, also known as UV Absorber UVBP-6, Light Stabilizer BP-6, Bis(2-hydroxy-4-methoxyphenyl)methanone, 2,2-Dihydroxy-4,4-dimethoxybenzophenone, 4,4-Dimethoxy-2,2-dihydroxybenzophenone, Benzophenone-6, or UVBP-6, is a chemical compound used in various applications to protect materials from the harmful effects of UV radiation.

BP-6 is produced by Ningbo Inno Pharmchem Co., Ltd., a leading manufacturer, supplier, and factory of high-quality chemicals and pharmaceutical intermediates. The company's expertise in chemical synthesis, process optimization, and quality control ensures that its products meet the highest standards of safety, purity, and performance.

BP-6 is a white or light yellow crystalline powder with a molecular weight of 317.33 g/mol and a melting point of 96-99°C. It is soluble in organic solvents such as ethanol, methanol, acetone, and chloroform but insoluble in water. BP-6 is stable under normal conditions but can degrade under prolonged exposure to UV radiation, heat, or moisture.

BP-6 is widely used in the plastics, coatings, adhesives, and fibers industries as a UV absorber and light stabilizer. It can prevent the degradation and discoloration of polymers caused by UV radiation, which can lead to loss of mechanical properties, cracking, chalking, and yellowing. BP-6 can also improve the weatherability and durability of materials exposed to outdoor or indoor light sources.

BP-6 can be used alone or in combination with other UV absorbers, antioxidants, or HALS (hindered amine light stabilizers) to achieve optimal performance. Its dosage depends on the type of material, the processing conditions, and the desired level of protection. Typically, BP-6 is added at a concentration of 0.1-2% by weight of the polymer.

BP-6 is compatible with a wide range of resins, including polyolefins, PVC, polyesters, polycarbonates, acrylics, and styrenics. It can be incorporated into the polymer matrix during extrusion, injection molding, or other processing methods. BP-6 can also be used in coatings, paints, and inks to improve their UV resistance and color stability.

BP-6 is a safe and effective UV absorber when used properly. It has been extensively tested for its toxicity, carcinogenicity, and eco-toxicity by various regulatory agencies, such as the US Environmental Protection Agency (EPA) and the European Chemicals Agency (ECHA). BP-6 has been approved for use in food contact materials, cosmetics, and other consumer products.

However, like any chemical substance, BP-6 should be handled with care and according to the recommended safety precautions. It should be stored in a cool, dry, and well-ventilated area, away from heat sources, flames, or sparks. It should be kept out of reach of children and pets. In case of skin or eye contact, rinse with plenty of water and seek medical attention if necessary. BP-6 should be used only by trained personnel who are familiar with its properties and hazards.

In conclusion, BP-6 Ultraviolet Absorber is a high-quality chemical product produced by Ningbo Inno Pharmchem Co., Ltd. that offers excellent UV protection and light stability for a wide range of materials. Its compatibility, versatility, and safety make it a popular choice for manufacturers and consumers worldwide. If you are looking for a reliable and effective UV absorber, BP-6 is definitely worth considering.
