Selecting the appropriate light stabilizer is a critical decision for manufacturers aiming to protect their products from the damaging effects of UV radiation. NINGBO INNO PHARMCHEM CO.,LTD. offers a high-performance solution in the form of HS-508 (292) Light Stabilizer, a versatile liquid Hindered Amine Light Stabilizer (HALS) with a well-defined set of properties and broad applicability. This guide aims to elucidate the characteristics of HS-508 (292) to aid in informed selection.

Understanding the Key Properties of HS-508 (292)

HS-508 (292) is characterized by its liquid appearance, making it exceptionally easy to handle and incorporate into various formulations. Its chemical name often relates to mixtures of hindered amines, such as bis(1,2,2,6,6-pentamethyl-4-piperidinyl) sebacate and methyl(1,2,2,6,6-pentamethyl-4-piperidinyl) sebacate, with a CAS number of 41556-26-7. Its high purity, often exceeding 99%, ensures consistent and reliable performance. Key physical properties, such as a low melting point of 20°C, a boiling point of 220°C (at 26.7 Pa), and a density of 0.9925 g/ml, contribute to its ease of use across different processing conditions. Furthermore, its solubility profile, with high solubility in solvents like styrene, acetone, and toluene, makes it compatible with a wide range of chemical systems, particularly polyols, which is vital for its recommended use in polyurethanes.
