Polyolefins, such as polyethylene (PE) and polypropylene (PP), are ubiquitous in modern applications, from packaging films and automotive components to construction materials and agricultural films. However, these versatile polymers are susceptible to degradation when exposed to ultraviolet (UV) radiation. To combat this, the integration of advanced additives like Hindered Amine Light Stabilizers (HALS) is crucial. For manufacturers of polyolefin products, understanding the role and benefits of specific HALS, such as our Light Stabilizer 622, is key to ensuring product longevity and performance. As a dedicated manufacturer and supplier, we aim to provide clarity on why HALS 622 is a preferred choice for many.

Light Stabilizer 622, also known by its CAS number 65447-77-0, stands out as an oligomeric HALS. Its designation as 'oligomeric' refers to its polymeric structure, which confers significant advantages over lower molecular weight stabilizers. The primary benefit of this higher molecular weight is its dramatically reduced volatility and migration. This means that once incorporated into the polymer matrix, Light Stabilizer 622 is far less likely to evaporate during high-temperature processing or leach out over time due to contact with solvents or environmental factors. This characteristic is particularly important for applications requiring long-term stability and where product integrity must be maintained.

For polyolefin applications such as PE films, injection-molded parts, and rotational molding products, the consistent protection offered by HALS 622 is invaluable. It effectively intercepts the photo-oxidative degradation pathways that can lead to surface chalking, loss of gloss, and embrittlement. Furthermore, its compatibility with carbon black and high pigment loadings makes it an excellent choice for colored polyolefin articles where UV protection is often more challenging to achieve uniformly.

Procurement managers and product formulators often look for suppliers who can provide not only high-quality chemicals but also reliable supply chains and competitive pricing. We pride ourselves on being a trusted manufacturer and supplier of Light Stabilizer 622 from China, ensuring that our clients can buy with confidence. Our commitment to quality control and efficient production processes means you receive a consistent, high-purity product that meets your specifications.

The effectiveness of Light Stabilizer 622 is further amplified when used in conjunction with other stabilizers, such as antioxidants. This synergistic approach ensures a multi-layered defense against degradation, extending the usable life of your polyolefin products significantly. For those in the market to purchase or obtain a quote for Light Stabilizer 622, exploring its unique properties and benefits reveals why it is a staple in advanced polymer formulations.
