SI Group UV Stabilizers


SI Group UV Stabilizers prevent photo-oxidative degradation in thermoplastic or rubber parts caused by ultraviolet light. The range of products include benzophenones, benzotriazoles, and hindered amine light stabilizers (HALS) to provide options on volatility, color sensitivity, solubility, and resin and pigment compatibility.

Problems Solved

Color stability issues caused by exposure of polymers to light and UV rays FDA clearances for the use of light and UV stabilizers in food contact films and applications Degradation of organic polymers by exposure to UV radiation High volatility and low thermal stability of commercially available light and UV stabilizers Long lead time, high cost, and minimum order quantity of UV and light stabilizers
