In the dynamic world of polymer manufacturing, ensuring the long-term durability and aesthetic appeal of plastic products is a constant challenge. Ultraviolet (UV) radiation from sunlight is a primary environmental factor that degrades polymers, leading to yellowing, embrittlement, and loss of mechanical strength. To combat this, formulators rely on effective UV absorbers. Among the most potent and versatile are benzophenone-based UV absorbers, with 2,4-Dihydroxybenzophenone being a prime example.

As a dedicated manufacturer and supplier of high-quality chemical additives, we understand the critical need for reliable UV protection in plastics. Our 2,4-Dihydroxybenzophenone (CAS 131-56-6) is engineered to provide exceptional performance, safeguarding your plastic products against the harshest UV conditions.

Understanding UV Degradation in Plastics

Polymers are complex organic molecules. When exposed to UV radiation, these molecules can absorb energy, leading to bond breakage and the formation of free radicals. These free radicals can initiate a cascade of degradation reactions, altering the polymer’s physical and chemical properties. This is particularly evident in:

  • Color Change: Yellowing or discoloration is a common symptom of UV exposure.
  • Loss of Mechanical Properties: Plastics can become brittle, crack, or lose tensile strength.
  • Surface Degradation: Chalking or surface dulling can occur, impacting appearance and functionality.

The Advantage of 2,4-Dihydroxybenzophenone in Plastics

Our 2,4-Dihydroxybenzophenone offers significant advantages for plastic manufacturers:

  • Broad Spectrum UV Absorption: It effectively absorbs UV light in the 280-320 nm range, a critical window for preventing photodegradation.
  • Excellent Compatibility: This UV absorber demonstrates good solubility in common organic solvents and excellent compatibility with a wide array of polymers. This ease of incorporation ensures uniform distribution within the plastic matrix, maximizing its protective effect.
  • Prevention of Yellowing: It is particularly effective in preventing yellowing in polymers like polystyrene, maintaining the clarity and visual appeal of products.
  • Improved Mechanical Properties: For materials such as polymethacrylates, it contributes to maintaining optical clarity and mechanical integrity, even under prolonged UV exposure.
  • Manufacturer-Direct Supply: As a reliable manufacturer and supplier based in China, we offer this essential additive at competitive prices, ensuring your production costs remain optimized.
