Hindered Amine Light Stabilizers (HALS)

The intermediates for hindered amine light stabilizers (HALS) are key chemicals for synthesizing high-performance HALS. They play an important role in the supply chain for light stabilizers. Thanks to their specifically designed molecular structures, these intermediates give the final products an exceptional radical scavenging capability, making them long-acting stabilizers.

Hindered Amine Light Stabilizers

Hindered Amine Light Stabilizers (HALSs) are a class of highly effective light stabilizers for polymeric materials, providing long-term photostability through a unique radical scavenging mechanism. Unlike traditional UV absorbers that absorb UV radiation directly, HALSs offer superior protection against material degradation by inhibiting photo-oxidation through chemical means.

UV Absorbers

UV absorbers are functional additives designed to absorb ultraviolet (UV) radiation, protecting materials or skin from UV damage. Their mechanism involves selective absorption of UV light (200-400nm) through specific molecular structures, which convert the energy into harmless heat or lower-energy emissions, thereby minimizing penetration and harm.

Antioxidants

Antioxidants are essential chemical additives that effectively inhibit oxidative degradation of polymers by interrupting oxidation chain reactions. As a core component of material stabilization systems, antioxidants are widely used in plastics, rubbers, lubricants, petroleum products and other industrial fields.
