UV radiation can cause significant damage to materials and products, leading to discoloration, degradation, and reduced performance. This is particularly true for polymers, plastics, and coatings, which are often used in outdoor applications and exposed to sunlight. To protect against UV radiation and ensure the longevity of these materials, UV absorbers are used. One of the most effective UV absorbers available today is UV-329, also known as BASF light stabilizer Tinuvin 329 or Cytec Light Stabilizer CYASORB UV-5411. This powerful compound is produced by Ningbo Inno Pharmchem Co., Ltd., a leading manufacturer of high-quality UV stabilizers and other specialty chemicals.
What is UV-329?
UV-329 is a benzotriazole derivative that absorbs UV radiation in the 290-400 nm range. It is a highly effective UV absorber for polymers, plastics, and coatings, providing excellent protection against UV-induced degradation and discoloration. UV-329 is a light yellow powder, soluble in common organic solvents, and compatible with a wide range of polymers, including polyethylene, polypropylene, PVC, PET, polycarbonate, and others.
UV-329 is also known by several other names, including Oxytriazole, 2-(2-Hydroxy-5-tert-octylphenyl)benzotriazole, 2-[2-Hydroxy-5-(1,1,3,3-tetramethylbutyl)phenyl]benzotriazole, 2-[2-Hydroxy-5-tert-octylphenyl)benzotriazole, 2-(2H-benzotriazol-2-yl)-4-(1,1,3,3-tetramethylbutyl)phenol, Octrizole, Ultraviolet Absorber UV-329, and others.
Why choose UV-329?
UV-329 is one of the most effective UV absorbers available today, offering several benefits over other UV stabilizers. Some of the key advantages of UV-329 include:
1. Excellent UV absorption: UV-329 is a highly effective UV absorber, providing excellent protection against UV radiation in the 290-400 nm range, which is the most damaging part of the solar spectrum. It absorbs UV radiation by converting it into harmless heat energy, preventing it from causing damage to the polymer matrix.
2. Broad compatibility: UV-329 is compatible with a wide range of polymers, including polyethylene, polypropylene, PVC, PET, polycarbonate, and others. It can be used in various applications, including films, fibers, molded parts, and coatings, without affecting their properties.
3. High thermal stability: UV-329 has excellent thermal stability and does not degrade or decompose at high temperatures. It can withstand processing temperatures up to 300°C without losing its UV absorption properties.
4. Low volatility: UV-329 is a low-volatility compound, which means it does not evaporate or migrate easily from the polymer matrix. This ensures long-term UV protection and reduces the risk of blooming or staining.
5. Cost-effective: UV-329 is a cost-effective solution for UV protection, offering high performance at a reasonable price. It is available in various grades to suit different applications and processing conditions.
UV-329 vs. other UV stabilizers
There are several other UV stabilizers available on the market, such as HALS (Hindered Amine Light Stabilizers), benzophenones, and triazines. However, UV-329 offers several advantages over these alternatives. For example:
- HALS are effective against UV radiation but are not suitable for all polymers and can cause yellowing or blooming. They also require the presence of oxygen to function, which limits their performance in enclosed environments.
- Benzophenones are effective in the UV-B range but do not provide sufficient protection in the UV-A range. They can also cause discoloration and yellowing over time.
- Triazines are effective in the UV-A range but are not suitable for all polymers and can cause yellowing or staining. They also require a co-stabilizer to function, which adds to the cost and complexity of the formulation.
UV-329, on the other hand, provides broad-spectrum UV protection, is compatible with various polymers, and does not cause discoloration or staining. It is also a cost-effective solution for UV protection, making it an ideal choice for many applications.
