The relentless assault of ultraviolet (UV) radiation from the sun poses a significant threat to the integrity and longevity of many materials, particularly polymers. For industries ranging from plastics manufacturing to coatings and textiles, understanding how to effectively combat UV-induced degradation is critical for product durability and consumer satisfaction. Central to this defense is the application of specialized UV absorbers, among which 2,4-Dihydroxybenzophenone (also known as UV-0 or BP-1, CAS No. 131-56-6) holds a prominent position.

At NINGBO INNO PHARMCHEM CO.,LTD., we are dedicated to providing advanced chemical solutions that empower manufacturers. As a leading supplier and manufacturer of functional material additives in China, our 2,4-Dihydroxybenzophenone is engineered to deliver superior UV protection, ensuring that your products maintain their performance and aesthetic qualities even under prolonged UV exposure.

Understanding UV Absorption: The Role of Benzophenones

UV radiation, typically categorized into UVA, UVB, and UVC, can initiate photochemical reactions within polymer structures. These reactions lead to chain scission, cross-linking, and the formation of chromophores, resulting in visible degradation like yellowing, cracking, and loss of mechanical strength. UV absorbers like 2,4-Dihydroxybenzophenone function by:

  • Absorbing UV Light: They selectively absorb specific wavelengths of UV radiation, primarily in the higher-energy UVB and shorter UVA range (280-340 nm for UV-0).
  • Dissipating Energy: Upon absorbing UV photons, the molecule enters an excited state. It then safely dissipates this energy through non-radiative pathways, such as vibrational relaxation, returning to its ground state without causing damage to the surrounding polymer matrix.
  • Preventing Degradation: By intercepting the UV radiation before it can initiate detrimental photochemical processes in the polymer, UV absorbers effectively shield the material.

The benzophenone structure of 2,4-Dihydroxybenzophenone, with its hydroxyl groups, enhances its ability to undergo tautomerization and efficiently dissipate absorbed energy, making it a highly effective UV stabilizer. This is particularly beneficial for polymers like polyolefins, PVC, and polystyrene, where maintaining clarity, color, and mechanical properties is often essential.
