For procurement managers and R&D scientists in the chemical and plastics industries, selecting the right additives is crucial for product performance and market competitiveness. Light Stabilizer 944, a high-performance Hindered Amine Light Stabilizer (HALS), has emerged as a go-to solution for enhancing the durability and lifespan of polymers. This article explores its key properties and the diverse applications where it proves invaluable.

At its core, Light Stabilizer 944 is characterized by its high molecular weight and polymeric structure. This imparts several critical advantages: low volatility, superior resistance to extraction, and excellent thermal stability. These attributes are highly sought after by product formulators, as they ensure the additive remains effective throughout the polymer’s processing and service life. When researching the Light Stabilizer 944 CAS 70624-18-9 price, these performance metrics are key considerations for value assessment.

Typical specifications for Light Stabilizer 944 often include its appearance, typically a white to light yellow powder or granules, and a defined melting point range of 110-130°C. Its molecular weight usually falls between 2000-3100 g/mol, a testament to its polymeric nature. Light transmittance values at specific wavelengths (e.g., ≥93% at 450nm) further indicate its purity and suitability for applications where optical clarity is important. For companies looking to buy Light Stabilizer 944 manufacturer-grade products, these specifications are vital for ensuring quality control.

The application spectrum for Light Stabilizer 944 is remarkably broad. It is extensively used in polyolefins such as polypropylene (PP) and polyethylene (PE), including thin films and fibers, where UV exposure is a major concern. Its effectiveness extends to olefin copolymers like EVA, as well as engineering plastics like polyamides (PA) and polyurethanes (PU), and even flexible and rigid PVC. This versatility makes it a staple for manufacturers in automotive, construction, agriculture, and textiles.

When considering the properties of high molecular weight hindered amine light stabilizer, one must also acknowledge its synergistic capabilities. Light Stabilizer 944 works exceptionally well in conjunction with antioxidants and UV absorbers, creating a robust protection system that significantly outlasts the performance of individual components. This integrated approach is essential for applications demanding long-term outdoor exposure resistance.

For businesses seeking to enhance the UV stability of their products, understanding where to source this vital additive is crucial. Engaging with a reputable Light Stabilizer 944 for polyolefins supplier ensures access to not only the product itself but also the technical know-how required for optimal formulation. Many companies in China are well-positioned to serve as this trusted source, offering competitive pricing and reliable delivery.

In summary, Light Stabilizer 944’s unique combination of high molecular weight, low volatility, broad polymer compatibility, and synergistic potential makes it an indispensable component for modern polymer formulations. By understanding its detailed properties and application benefits, R&D scientists and purchasing managers can make informed decisions to improve product performance and longevity.
