For R&D scientists and product formulators in the plastics industry, selecting the correct UV stabilizer is crucial for ensuring the longevity and aesthetic appeal of their creations. The choice of stabilizer directly impacts a product's resistance to weathering, color retention, and overall mechanical integrity when exposed to sunlight. Understanding the different types of UV absorbers and their specific properties is key to making an informed decision. As a dedicated manufacturer and supplier, we aim to guide you through this selection process.

One of the most versatile and high-performing UV stabilizers available is UV Absorber 234 (CAS: 70321-86-7). This hydroxyphenyl benzotriazole derivative is prized for its ability to absorb a broad spectrum of UV light (300-400nm), effectively preventing photodegradation. Its molecular structure provides excellent light stability, meaning it doesn't easily break down when exposed to UV radiation itself. This longevity of the stabilizer is paramount for long-term protection.

When evaluating UV absorbers, consider factors such as volatility and compatibility. UV Absorber 234 boasts low volatility, making it an excellent choice for polymers that are processed at elevated temperatures. This property ensures that the stabilizer remains within the polymer matrix during manufacturing, rather than evaporating. Its compatibility with a wide range of substrates, including polycarbonates, polyesters, polyacetals, and polyolefins, further enhances its utility. For those looking to purchase in larger quantities, understanding the cost-effectiveness and availability from a reliable manufacturer like ourselves is essential. We offer competitive pricing for this vital additive.

Another critical aspect is the concentration. Typical use levels for UV Absorber 234 range from 0.15% to 0.60%, depending on the specific polymer and the desired level of protection. It can also be used synergistically with other light stabilizers, such as Hindered Amine Light Stabilizers (HALS), to provide even greater protection. If you are a procurement manager seeking to enhance your product's performance and durability, we highly recommend exploring our range of UV Absorber 234.
