For procurement professionals in the plastics industry, ensuring the quality and performance of additives is paramount. Ultraviolet (UV) radiation poses a significant challenge, leading to material degradation that can compromise product aesthetics and functionality. 2,4-Dihydroxybenzophenone (UV-0, BP-1, CAS No. 131-56-6) is a highly effective UV absorber vital for protecting a wide range of plastic materials. This guide aims to provide procurement managers with essential information on its application and sourcing, particularly from China.

Why is UV Protection Crucial for Plastics?

Plastics, when exposed to UV light, undergo photochemical reactions that break down polymer chains. This can manifest as:

  • Yellowing and Fading: Loss of color intensity and the development of an undesirable yellow hue.
  • Brittleness: A significant reduction in flexibility and an increased tendency to crack or shatter.
  • Surface Degradation: Chalking, surface roughness, and loss of gloss.
  • Loss of Mechanical Strength: Reduced tensile strength, impact resistance, and overall structural integrity.

To combat these issues and extend product lifespan, UV absorbers are incorporated during the compounding or manufacturing process.

The Role of 2,4-Dihydroxybenzophenone (UV-0/BP-1)

2,4-Dihydroxybenzophenone is a benzophenone derivative that excels at absorbing UV radiation in the 280-340 nm range. This specific spectrum is particularly damaging to many common polymers. Its key advantages include:

  • Effective UV Absorption: It efficiently converts UV energy into harmless heat, protecting the polymer matrix.
  • Broad Compatibility: It integrates well into various polymers, including polyolefins (like PE and PP), PVC, and polystyrene, making it a versatile choice for diverse applications such as outdoor furniture, automotive components, packaging films, and construction materials.
  • Good Stability: It exhibits good light and thermal stability, ensuring its effectiveness throughout the polymer processing stages and during the product's service life.
  • Cost-Effectiveness: Compared to some other UV stabilizers, it offers a good balance of performance and price, especially when sourced efficiently.

Sourcing 2,4-Dihydroxybenzophenone from China: What Procurement Managers Need to Know

China has emerged as a global leader in chemical manufacturing, offering high-quality products at competitive prices. For procurement managers sourcing 2,4-Dihydroxybenzophenone, partnering with a reputable manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. ensures:

  • High Product Purity: We guarantee a minimum assay of 99%, along with low ash and volatile matter content, critical for consistent performance in demanding applications.
  • Competitive Pricing: As a direct manufacturer, we offer attractive pricing, particularly for bulk orders, allowing for significant cost savings. We encourage you to request a quote to understand these benefits.
  • Reliable Supply Chain: Our manufacturing capabilities and robust logistics ensure a stable and timely supply, mitigating risks of production downtime.
  • Technical Documentation: Access to comprehensive technical data sheets (TDS) and safety data sheets (SDS) is vital for R&D and quality control teams.

Key Considerations for Application in Plastics:

  • Dosage: Typical usage levels range from 0.1% to 0.5% for thin materials and 0.05% to 0.2% for thicker products, depending on the specific polymer and exposure conditions.
  • Processing: It can be incorporated during the extrusion, injection molding, or compounding phases. Its good solubility in common organic solvents and compatibility with many polymers simplify integration.
  • Synergistic Effects: For enhanced protection, it can sometimes be used in conjunction with light stabilizers (like HALS), although UV-0 itself offers significant standalone protection.
