NINGBO INNO PHARMCHEM CO.,LTD. is pleased to highlight Sunovin 5586, a key product in our portfolio of high-quality chemical additives. As a leading supplier dedicated to providing essential raw materials for the polymer industry, we understand the critical need for effective stabilization solutions against environmental degradation.

Sunovin 5586 is a highly effective UV absorber and light stabilizer, chemically known as Hexadecyl 3,5-Bis-Tertbutyl-4-Hydroxybenzoate, with the CAS number 67845-93-6. This versatile additive is particularly well-suited for use in polyolefin applications, including films, fibers, and molded articles. Its primary function is to protect these materials from the harmful effects of ultraviolet radiation, which can lead to degradation, loss of mechanical properties, and discoloration over time. By absorbing UV light, Sunovin 5586 helps to significantly extend the service life and maintain the aesthetic appeal of polyolefin products.

One of the standout characteristics of Sunovin 5586 is its excellent property profile. It is presented as a white to off-white powder, making it easy to handle and incorporate into various polymer processing methods. Key advantages include low volatility, ensuring minimal loss during processing and throughout the product's lifespan. It also demonstrates good solubility in polyolefin matrices and excellent compatibility with other common additives such as hindered amine light stabilizers (HALS) and antioxidants, allowing for the creation of synergistic stabilization packages tailored to specific application requirements.

Furthermore, Sunovin 5586 is recognized for its robust performance under challenging conditions. Its molecular weight is approximately 475 g/mol, contributing to its stability. Quality parameters such as low ash content (typically ≤ 0.1%) and minimal volatile matter (≤ 0.5%) underscore its purity and consistent performance. The melting point ranges between 59-64ºC, facilitating easy dispersion during compounding.

The application of Sunovin 5586 in polyolefins provides tangible benefits, such as improved weathering resistance, reduced yellowing, and prolonged retention of physical strength. This makes it an indispensable additive for a wide range of polyolefin products exposed to sunlight, from agricultural films and geomembranes to automotive components and consumer goods.
