The effectiveness of any polymer additive is intrinsically linked to its ability to remain within the polymer matrix and maintain its functional properties over time. This is especially true for light stabilizers, which are crucial for protecting plastics from the relentless assault of UV radiation. Key to achieving this long-term protection are two critical characteristics: low volatility and low reactivity with other components in the polymer system.

NINGBO INNO PHARMCHEM CO.,LTD. prides itself on developing advanced polymer additives that embody these essential traits. Our high molecular weight Hindered Amine Light Stabilizers (HALS), such as the N,N'-Bis(2,2,6,6-tetramethyl-4-piperidinyl)-1,6-hexanediamine polymers, are specifically engineered for low volatility. This means they are far less likely to evaporate or be lost during high-temperature processing steps like injection molding or extrusion. Furthermore, their low volatility ensures they remain sequestered within the polymer, providing consistent and durable protection throughout the product's lifecycle.

Equally important is low reactivity with other materials present in the polymer formulation. Many polymer systems contain acidic by-products from processing, residual catalysts, or other additives that can interact with and deactivate traditional stabilizers. Our HALS are formulated to exhibit minimal reactivity with such acidic components. This ensures that the stabilizer's performance is not compromised, allowing it to effectively scavenge free radicals and protect the polymer from UV-induced degradation, even in complex formulations.

The combination of low volatility and low reactivity offers a significant advantage for manufacturers. It leads to more predictable and reliable performance of the final product, extending its service life and maintaining its aesthetic and mechanical integrity. For applications such as automotive exteriors, outdoor construction materials, and agricultural films, where exposure to sunlight and environmental factors is constant, these properties are not just beneficial—they are essential for product longevity.
