¿Qué es el Estabilizador UV UV-1 CAS 57834-33-0？

UV Stabilizer UV-1 (CAS 57834-33-0) is a highly effective ultraviolet light absorber used to protect polymers, coatings, and plastics from UV-induced degradation. Also referred to as Light Stabilizer UV-1 or Omnistab UV 1, this compound belongs to the benzophenone derivative family and provides excellent light stability by absorbing harmful UV radiation.

Estabilizador UV UV-1 es de color amarillo claro líquido con fórmula molecular C17H18N2O2, peso molecular 282.3, humedad ≤1.0%, el punto de ebullición de 188 ~ 190℃/13Pa, densidad relativa: 1.127, la viscosidad (20℃) de alrededor de 4752mPa·s, el índice de refracción de 1.64. Solubilidad: >50 en etanol, >50 en alcohol isopropílico, >50 en acetato de butilo, y cero en el agua. En términos de la PU,UV-1 es mejor que el otro anti-ultravioleta de los agentes, y se utiliza en espuma de materiales, revestimientos, cuero y placas.

It is particularly suitable for transparent and light-colored systems, where long-term protection against discoloration, brittleness, and loss of mechanical strength is critical. As a China UV Absorber UV-1 supplier, we provide consistent quality and competitive pricing for global customers.
