For product formulators and chemical engineers, understanding the precise properties and applications of additives like UV-328 is crucial for developing high-performance materials. UV-328 is a leading UV absorber that plays a vital role in protecting polymers and organic substrates from the damaging effects of ultraviolet radiation. NINGBO INNO PHARMCHEM CO.,LTD., as a specialized manufacturer and supplier, provides a deep dive into this essential chemical.

The Technical Profile of UV-328

UV-328, bearing the CAS number 25973-55-1, is a benzotriazole derivative that functions by absorbing UV light in the 270-340 nm spectrum. This characteristic absorption mechanism is key to preventing photodegradation, which manifests as discoloration, chalking, and loss of mechanical strength in polymers. From a chemical manufacturer's perspective, UV-328 offers several compelling technical advantages: its excellent compatibility with a wide array of polymers, including polyolefins, polyesters, styrenics, and polycarbonates; its low volatility, which is critical for maintaining additive concentration during high-temperature processing operations like extrusion and injection molding; and its significant wash resistance, ensuring that the UV protection remains effective even when the material is exposed to cleaning agents or environmental liquids.

Formulation Considerations and Usage Recommendations

Product formulators will find UV-328 to be a versatile additive. Its compatibility profile allows for seamless integration into diverse polymer systems. The recommended dosage typically ranges from 0.1% to 0.5% by weight, contingent upon the specific polymer, processing conditions, and the desired level of UV protection. For instance, in polyethylene (PE) and polypropylene (PP) applications, typical loadings are between 0.2% and 0.4%. For polycarbonate (PC) and polyester (PET, PBT), dosages of 0.15% to 0.3% and 0.3% to 0.5% are common, respectively. As a dedicated UV-328 supplier, NINGBO INNO PHARMCHEM CO.,LTD. can provide detailed technical data sheets (TDS) to assist formulators in optimizing its use.
