2,4-Dihydroxybenzophenone

Product Overview

2,4-Dihydroxybenzophenone, commercially recognized as UV Absorber BP-1 or UV-0, is a high-performance benzophenone-based ultraviolet absorber designed to enhance the longevity and stability of various polymer matrices. With the CAS registry number 131-56-6, this chemical compound functions by effectively absorbing harmful UV radiation in the wavelength range of 280 to 340 nanometers. By dissipating this energy as harmless heat, it prevents photo-oxidative degradation, thereby preserving the mechanical integrity and aesthetic appearance of finished products exposed to sunlight.

Our manufacturing process ensures exceptional purity levels, typically exceeding 99.5%, which is critical for maintaining clarity and preventing discoloration in transparent applications. As a leading global manufacturer, we adhere to strict quality control protocols, providing comprehensive Certificates of Analysis (COA) with every batch to guarantee consistency and reliability for industrial users.

Key Specifications

Industrial Applications

UV Absorber BP-1 is versatile and compatible with a wide array of synthetic materials. Its primary function is to act as a stabilizer against UV-induced weathering, making it indispensable in industries where product durability is paramount. The chemical structure allows for excellent solubility and dispersion within polymer chains, ensuring uniform protection throughout the material.

• Polyolefins: Enhances the weatherability of polyethylene and polypropylene products used in outdoor construction and packaging.
• Polyvinyl Chloride (PVC): Prevents yellowing and brittleness in PVC pipes, profiles, and flooring materials exposed to sunlight.
• Polystyrene: Maintains impact strength and clarity in consumer goods and electronic housings.
• Coatings and Adhesives: Protects surface finishes from cracking and peeling caused by prolonged UV exposure.

Storage and Handling

2,4-Dihydroxybenzophenone is classified as non-dangerous goods for transport, with no specific UN number or transport hazard class required. It is non-toxic, non-flammable, and non-corrosive under normal handling conditions. For optimal storage stability, the product should be kept in a cool, dry, and well-ventilated area, away from direct sunlight and moisture. The standard packaging consists of cardboard drums lined with plastic bags, with a net weight of 25kg per drum, though custom packaging solutions are available to meet specific logistical requirements. Proper handling ensures the material retains its high performance characteristics over extended storage periods.
