UV Stabilizer

SUNOVIN can be categorised by two general classifications - ultraviolet light absorbers (UVA) and hindered amine light stabilizers (HALS). UVAs slow down the degradation process by preferentially absorbing harmful ultravoilet radiation and dissipating it as thermal energy. However, high concentrations of absorbers and sufficient thickness of the polymer are required before enough absorption takes place to effectively remove photo degradation.

HALS do not absorb UV radiation, but act to inhabit degradation of the polymer. Significant levels of stabilization are achieved at relatively low concentrations. HALS high efficiency and longevity are due to a cyclic process wherein the HALS are regenerated rather than consumed during the stabilization process.

The industries to which SUNSHOW serves are Petrochemicals, Agricultural film, Anti bacteria, Coatings, Inks, Personal Care, Elastic floor, Wires & Cables, Masterbatches, and Adhesives.
