When it comes to producing high-quality products, manufacturers need to ensure that their materials remain stable and durable under various environmental conditions. This is especially true when it comes to products that are exposed to light, which can cause discoloration, degradation, and other negative effects. To prevent these issues, BASF has developed a state-of-the-art light stabilizer called Tinuvin 944, also known as Chimassorb 944.

Tinuvin 944 is a highly effective UV absorber that protects materials from the damaging effects of sunlight and other sources of UV radiation. It is particularly useful for applications in the automotive, construction, and packaging industries, as well as in coatings, adhesives, and other specialty materials. With its exceptional performance and reliability, Tinuvin 944 has become a top choice for manufacturers and suppliers around the world.

What is Tinuvin 944?

Tinuvin 944 is a light stabilizer that belongs to the class of hindered amine light stabilizers (HALS). HALS are a type of UV absorber that work by scavenging free radicals and other reactive species that are generated by the UV radiation. This prevents the degradation of the polymer chain and helps to maintain the original physical and chemical properties of the material.

Tinuvin 944 has several advantages over other types of HALS. For one, it has a highly efficient UV absorption spectrum that covers both the UV-A and UV-B regions. This means that it can provide broad-spectrum protection against a wide range of UV radiation. Additionally, Tinuvin 944 has a high level of thermal stability, which means that it remains effective even at high temperatures. This makes it an ideal choice for applications that require high-temperature processing or exposure to hot and humid environments.

Benefits of Tinuvin 944

There are several key benefits of using Tinuvin 944 in manufacturing and supply applications. First and foremost, it provides excellent UV protection, which helps to prevent discoloration, yellowing, and other forms of degradation. This is particularly important for products that are exposed to sunlight or other sources of UV radiation, such as automotive parts, building materials, and packaging materials.

Another benefit of Tinuvin 944 is its high level of compatibility with other materials. It can be easily added to a wide range of polymers, including polyolefins, PVC, and polystyrene, without affecting their physical or chemical properties. This makes it a versatile and flexible choice for manufacturers and suppliers who need to produce a variety of products with different materials.

In addition, Tinuvin 944 has a long-term stability, which means that it can provide reliable protection for extended periods of time. This is especially important for products that need to maintain their appearance and performance over several years, such as outdoor furniture, window profiles, and other building materials.

How to Use Tinuvin 944

Tinuvin 944 is available in both liquid and powder forms, depending on the specific needs of the application. It can be easily incorporated into the polymer matrix using standard processing techniques, such as extrusion, injection molding, or blow molding. The recommended dosage of Tinuvin 944 varies depending on the specific application, but typically ranges from 0.1% to 1.0% by weight of the polymer.

To ensure optimal performance, it is important to choose the right type of Tinuvin 944 for the specific application. BASF offers a range of Tinuvin 944 products with different molecular weights, melt points, and other properties to suit different processing and performance requirements.
