In the vast world of polymer additives, UV absorbers play a critical role in protecting plastics from the detrimental effects of ultraviolet radiation. For R&D scientists and procurement managers alike, understanding the nuances of these stabilizers is key to ensuring product longevity and performance. Among the most effective and versatile UV absorbers available today is UV Absorber 312, a high-performance oxalanilide compound. As a prominent manufacturer and supplier in China, we aim to provide a comprehensive overview of this vital additive, detailing its chemical properties, applications, and the advantages it offers to the plastics industry. For businesses looking to buy this essential component, our insights will highlight why sourcing from a trusted provider is crucial.

The Science Behind UV Protection in Plastics

Plastics are ubiquitous, found in everything from packaging and consumer goods to automotive parts and construction materials. However, many common polymers are susceptible to photodegradation when exposed to sunlight. UV radiation initiates chemical reactions that can lead to loss of color, reduced mechanical strength, cracking, and surface chalking. This degradation significantly shortens the lifespan and compromises the performance of plastic products. A UV absorber works by preferentially absorbing UV light and dissipating the energy as heat, thereby shielding the polymer matrix. The choice of UV absorber depends on the polymer type, processing conditions, and the specific UV exposure the product will face. For procurement managers, ensuring a stable and cost-effective supply of high-purity UV absorbers is a key operational goal.

UV Absorber 312: Chemical Profile and Key Advantages

UV Absorber 312, chemically known as N-(2-ethoxyphenyl)-N’-(2-ethylphenyl)oxamide, is a highly effective UV stabilizer, particularly noted for its strong absorption in the UV-B range. Its oxalanilide structure contributes to several desirable characteristics that make it a popular choice for plastics manufacturers:

  • Broad UV Spectrum Absorption: Its primary function is to absorb UV radiation, acting as a molecular shield for the polymer. This is crucial for outdoor applications and products with extended service life requirements.
  • Low Color and Non-Discoloring Nature: A significant benefit of UV Absorber 312 is its minimal impact on the color of the final plastic product. This makes it ideal for clear, transparent, or lightly colored applications where maintaining aesthetic appeal is important.
  • Excellent Thermal Stability: The compound exhibits good resistance to thermal degradation, which is essential for surviving the high temperatures often encountered during polymer processing techniques like extrusion or injection molding. This ensures the additive remains effective throughout the manufacturing process.
  • High Compatibility: UV Absorber 312 shows excellent compatibility with a wide range of polar polymers, including polyamides (PA), polyesters (PET, PBT), polyurethanes (PU), and polyvinyl chloride (PVC). This broad compatibility allows for its use in diverse plastic product lines.
  • Synergistic Effect: When formulated in combination with other light stabilizers, such as Hindered Amine Light Stabilizers (HALS), UV Absorber 312 can provide enhanced, synergistic UV protection, offering superior long-term performance.

Applications in the Plastics Industry

UV Absorber 312 finds extensive use in various plastic applications, including:

  • Engineering Plastics: Protecting components made from PA, PET, PBT, and PC used in automotive, electronics, and industrial equipment.
  • PVC Applications: Stabilizing both rigid and flexible PVC products, such as window profiles, pipes, flooring, and films.
  • Polyurethanes: Enhancing the lightfastness of PU foams, coatings, and elastomers used in furniture, automotive interiors, and footwear.
  • Adhesives and Sealants: Protecting polymeric adhesives and sealants that might be exposed to UV radiation.
