The sun emits a broad spectrum of electromagnetic radiation, with ultraviolet (UV) rays being particularly detrimental to organic materials like polymers. UV radiation is broadly categorized into three types: UV-A, UV-B, and UV-C. While UV-C is largely absorbed by the Earth's ozone layer, UV-A and UV-B rays reach the surface and can penetrate various materials, initiating photochemical reactions that lead to degradation.

The Dual Threat: UV-A and UV-B Radiation

UV-B radiation, typically in the 280-315 nm range, carries more energy and is the primary cause of sunburn. In polymers, it can lead to rapid surface degradation, yellowing, and loss of mechanical properties. UV-A radiation, on the other hand, spans 315-400 nm and penetrates deeper into materials. While less energetic than UV-B, its longer exposure times contribute significantly to long-term polymer aging, causing embrittlement, cracking, and color fade.

To ensure comprehensive protection, polymer formulations often require additives that can effectively absorb both UV-A and UV-B wavelengths. This is where advanced UV absorbers, such as UV Absorber UV-360 (CAS 103597-45-1), become indispensable.

UV Absorber UV-360: Comprehensive Protection from a Trusted Supplier

UV Absorber UV-360 is specifically engineered to offer robust protection across the entire 300-400 nm spectrum, with peak absorption in key areas that effectively neutralize both UV-A and UV-B threats. This broad-spectrum efficacy makes it a highly sought-after additive for applications demanding superior light stability and weather resistance. Its ability to convert absorbed UV energy into harmless thermal energy prevents photo-oxidative degradation, thereby extending the service life of polymers significantly.

As a leading manufacturer and UV-360 supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. ensures that our UV-360 meets the highest standards of purity and performance. Its low volatility is a critical advantage, allowing it to remain within the polymer matrix even at elevated processing temperatures, unlike some lower molecular weight UV absorbers that can volatilize or migrate out. This persistent protection is vital for applications such as automotive coatings, exterior building materials, and durable plastics.
