CESA® light 7501

CESA® light 7501 by Avient is hindered amine based UV light stabilizer masterbatch containing effective substance in PET carrier. It absorbs harmful UV radiation, dissipating it as harmless thermal energy. It acts as radical interceptor, effectively inhibiting polymer degradation. Significant stabilization levels can be achieved at relatively low concentrations, regardless of wall thickness. It is believed that it converts nitro-oxyl free-radicals under photo-oxidative conditions and may also cause the deactivation of carbonyl groups. It is highly recommended for injection extrusion in polyethylene terephthalate. CESA® light 7501 is used in food-, drug- and personal care product packaging, agricultural films, construction materials, lawn and garden equipments. The dosage rate is 1.0-3.0 %.
