NINGBO INNO PHARMCHEM CO.,LTD. is a leading supplier of high-quality chemical additives, dedicated to providing innovative solutions that enhance the performance and longevity of materials across numerous industries. We specialize in a range of plastic additives designed to protect polymers from environmental degradation, ensuring sustained quality and functionality. Among our key offerings is a high-performance polymeric Hindered Amine Light Stabilizer (HALS), specifically engineered to tackle the challenges of UV radiation and weather exposure in sensitive applications, particularly polyolefins.

Polyolefins, including polyethylene and polypropylene, are widely used materials due to their versatility and cost-effectiveness. However, their inherent structure makes them susceptible to degradation when exposed to ultraviolet (UV) light and heat from sunlight. This degradation process, known as photo-oxidation, leads to a cascade of negative effects, including discoloration, loss of mechanical strength (embrittlement, cracking), reduced flexibility, and overall premature product failure. This is a significant concern for applications like agricultural films, geotextiles, automotive parts, and outdoor furniture, where long-term durability under sunlight is critical.

Our polymeric HALS additive, identified by its chemical class and CAS number 82451-48-7, is a powerful tool in combating this degradation. It functions by effectively scavenging free radicals formed during the photo-oxidation process, thereby interrupting the chain reactions that lead to polymer breakdown. Unlike traditional UV absorbers that primarily prevent UV light from penetrating the material, HALS stabilizers provide protection even after UV light has been absorbed, offering sustained, long-term stability throughout the material's lifespan.

A key advantage of this specific HALS is its polymeric nature. This grants it exceptional properties crucial for demanding applications. It exhibits significantly lower volatility compared to lower molecular weight HALS, meaning less product is lost during processing (like extrusion or film blowing) or during the service life of the final product, especially at elevated temperatures. Furthermore, its polymeric structure results in minimal migration within the polymer matrix. This is vital for applications like thin films or fibers where migration can lead to surface blooming, reduced efficacy over time, or potential issues with indirect food contact or contact with soil in agricultural settings.

The physical form of the product is a slightly yellow solid, available as a powder or granular material, making it easy to handle and incorporate into various polymer processing techniques. Its melting point typically ranges from 110 to 130°C, and it boasts a low volatile matter content, generally ≤ 0.8%, indicating high purity and consistency. It demonstrates good solubility in appropriate polymer systems, facilitating uniform dispersion and optimal performance.

Primary applications where this polymeric HALS excels include Polyolefin Films, such as greenhouse films, agricultural mulch films, stretch wrap, and protective packaging films. In these applications, extending film life under intense sunlight exposure directly translates to economic benefits for farmers and reduced waste. It is also highly effective in Polyolefin Fibers used in geotextiles, artificial turf, ropes, and non-woven fabrics, preserving their tensile strength, color, and structural integrity for years.

Beyond films and fibers, this versatile additive contributes significantly to the durability of polyolefins in other areas. This includes injection-molded and extruded parts for Automotive interiors and exteriors, where resistance to sunlight and heat is essential. It is also used in Agricultural components, Cables and Wires, Adhesives, Coatings, and as a critical ingredient in Masterbatches. Its broad compatibility makes it suitable for a wide range of polyolefin formulations and processing methods.
