APPLICATIONS

Typical applications

Suitable processes and end-use scenarios.

The domestically produced ultraviolet absorber UV329 is a benzotriazole compound, appearing as a white to light yellow powder, with a melting point of 101-106°C and a flash point of 239.2°C. It features low volatility, high heat resistance, good dispersibility, and excellent UV absorption efficiency (peak at 343 nm). It is widely used in PC, PE, PP, PS, ABS resins, and outdoor products. By absorbing ultraviolet light of 270-380 nm, it prevents material yellowing and aging. The recommended dosage is 0.1%-1.0%, especially suitable for light-colored or colorless plastics, films, and fiber products for photostability protection, and is often used in combination with antioxidants.

Core Advantages

  • Excellent thermal stability: resistant to high temperatures up to 300°C, suitable for high-temperature injection molding processes
  • Low volatility design: under high-temperature processing conditions, the loss rate is less than 40% of that of ordinary products
  • Transparency system compatibility: does not affect the light transmittance and appearance of light-colored/transparent products
  • Synergistic effect: Can be used in combination with hindered amine light stabilizers (HALS) to enhance protective effects
  • Strict quality control management: Jointly customized by high-quality domestic and international suppliers, with batch-to-batch variation controlled within ±0.3%
  • Application convenience: powder particle size D50 ≤ 15 microns, evenly dispersed in the plastic substrate

TYPICAL APPLICATION FIELDS

  • Polyolefin materials: PE agricultural greenhouse film, PP outdoor furniture, HDPE pipes, etc.
  • Transparent products: acrylic signs, PS food packaging, PET beverage bottles, and other light-colored packaging materials
  • Synthetic fiber textiles: polypropylene outdoor fabrics, car sunshades, awning fabrics, and other fiber products
  • Special applications: solar backsheet films, photovoltaic module encapsulation films, LED lampshades, and other photosensitive materials
  • Synergistic formulation: Used in combination with antioxidants 168/1010, etc., to enhance overall aging performance
