Technical background
UV Green 007 (the equivalent of Tinuvin 1600) functions as a hydroxyphenyl-triazine UV absorber with a narrow but highly effective performance profile: it is designed to protect polymers by converting UV radiation into low-energy heat, preventing chain scission and surface degradation. Unlike benzotriazole or benzophenone systems, HPT technology provides higher thermal stability and lower volatility, enabling its use in polymers processed at temperatures above 260–300 °C. This makes UV Green 007 a reliable UV stabilizer for plastics, particularly in engineering polymers where conventional UV additives may show processing loss or insufficient long-term retention.
Chemical identity of UV Green 007
The chemical name of UV Green 007 (an alternative to Tinuvin 1600) is 2-hydroxyphenyl-s-triazine derivative.
CAS number: 204583-39-1

Product synonyms: UV Green 007, Tinuvin 1600, UV 1600
UV Green 007 (Tinuvin 1600) is a high-purity hydroxyphenyl-triazine UV absorber, identified in the chemical industry by its CAS number 204583-39-1. Its chemical properties provide excellent compatibility met engineering plastics, thin films and coatings, maintaining long-term stability even under high-temperature processing.
Performance advantages
UV 1600 is a hydroxyphenyl-triazine (HPT) class UV absorber providing broad-spectrum protection against UV-A and UV-B radiation. Its chemical structure absorbs harmful ultraviolet light, preventing polymer chain degradation, discoloration and surface embrittlement. This makes UV Green 007 a preferred UV stabiliser for outdoor-exposed plastics and coatings.
UV Green 007 exhibits low volatility and high thermal stability under high-temperature processing. Unlike many conventional UV absorbers, it remains stable during extrusion, injection moulding or other polymer processes above 260–300 °C. This allows its use in engineering plastics such as polycarbonate (PC), polyethylene terephthalate (PET/PBT), ABS, ASA, SAN and polyamide (PA).
UV Green 007 is compatible with transparent, pigmented and reinforced polymer systems. Its molecular design ensures uniform dispersion without affecting clarity, colour or mechanical properties. This makes it particularly suitable as a UV stabilizer for plastic, including thin films, sheets and coated materials.
The additive maintains transparency and prevents yellowing in clear polymers and coatings. It is suitable for applications requiring visual quality, such as automotive glazing, optical components, packaging films and decorative panels. Its performance ensures the polymer retains its original appearance while being protected from UV degradation.
By mitigating UV-induced degradation, UV Green 007 prolongs the service life of polymers and coatings exposed to sunlight or outdoor environments. Components maintain gloss, colour and mechanical properties for longer periods, reducing maintenance and replacement needs in applications such as construction, automotive and outdoor equipment.
UV Green 007 (Tinuvin 1600) is used in various sectors due to its versatility:
- Engineering plastics: PC, PET, PBT, PMMA, ABS, ASA, SAN, PA
- Thin films and sheets: transparent, co-extruded, or pigmented
- Coatings and surface finishes: long-term outdoor durability, industrial and automotive
- High-temperature processed components: automotive parts, structural polymers
