^{Product Overview: UV-1164 (CAS 2725-22-6)}

Performance Advantages

High Thermal Stability: Volatility <1% at 150°C; stable during high-temp processing (e.g., PC, PBT)

Broad Spectrum: Exceptional absorption 280-400 nm, protecting polymers from UV-A and UV-B

Low Color Contribution: Minimal initial color; ideal for natural and transparent grades

Synergistic: Works efficiently with HALS (e.g., RIASORB UV-292) and antioxidants

Non-hazardous for transport: Not classified as dangerous goods (IATA/IMDG)

Applications & End-uses

UV-1164 is utilized across diverse sectors requiring long-term UV stability under demanding conditions
