This document introduces two light stabilizer products: UV-944 and UV-2020.

Light Stabilizer UV-944

• Common Chinese Name: Light Stabilizer UV-944
• Chemical Name (Chinese): Poly{[6-[(1,1,3,3-Tetramethylbutyl)amino]-1,3,5-triazine-2,4-diyl][(2,2,6,6-tetramethyl-4-piperidyl)imino]-1,6-hexanediyl[(2,2,6,6-tetramethyl-4-piperidyl)imino]}
• CAS No.: 70624-18-9
• Appearance: Light yellow transparent granules
• Main Applications: Suitable for PP, LDPE, HDPE, XPE, EVA, POM, PU, PVC, and other materials, especially ideal for film products. Its function is to protect polymer materials from photo-degradation and thermal degradation caused by UV irradiation and long-term thermal aging.

Light Stabilizer UV-2020

• Common Chinese Name: Light Stabilizer UV-2020
• Chemical Name (Chinese): Copolymer of N,N’-bis(2,2,6,6-tetramethyl-4-piperidinyl)-1,6-hexanediamine and 2,4,6-trichloro-1,3,5-triazine, reacted with N-butyl-1-butanamine and N-butyl-2,2,6,6-tetramethyl-4-piperidinamine
• CAS No.: 192268-64-7
• Appearance: Light yellow granules
• Main Applications: Suitable for polyolefins (PP and PE) and blends of polyolefins with elastomers. It can be used in all polyolefins, especially PP fibers and textile fibers like films, fabrics, and packaging. Also applicable in marine products such as water platforms and floating bodies, as well as PP fibers for automotive interior carpet yarns and non-woven fabrics.
  • Key Features:
    1. A high molecular weight hindered amine light stabilizer (HALS) with good compatibility and high resistance to extraction.
    2. Very narrow molecular weight distribution, ensuring stable performance during use and processing.
    3. Offers superior UV stability and long-term thermal stability.
    4. Provides unique long-term thermal protection for PP filler and carbon black filler systems.
