UV radiation can cause significant damage to polymers, leading to their degradation, discoloration, and loss of physical properties. To protect polymers from the harmful effects of UV radiation, manufacturers must incorporate UV absorbers or light stabilizers into their formulations.

One such UV absorber that has gained popularity among manufacturers is Cytec's Cyasorb THT 4611. Produced by Ningbo Inno Pharmchem Co., Ltd, Cyasorb THT 4611 is a high-performance light stabilizer that provides excellent protection against UV radiation.

What is Cyasorb THT 4611?

Cyasorb THT 4611 is a UV absorber or light stabilizer that belongs to the class of hindered amine light stabilizers (HALS). It is a highly effective UV absorber that can protect polymers from UV radiation-induced degradation, discoloration, and loss of physical properties. Cyasorb THT 4611 is a liquid HALS that is soluble in a wide range of solvents, including water.

How does Cyasorb THT 4611 work?

Cyasorb THT 4611 works by scavenging free radicals generated by UV radiation. When exposed to UV radiation, polymers generate reactive free radicals that can initiate a chain reaction leading to their degradation. Cyasorb THT 4611 traps these free radicals and converts them into stable molecules, thereby preventing further degradation of the polymer. In addition, Cyasorb THT 4611 also absorbs UV radiation, thereby reducing the amount of UV radiation that reaches the polymer.

What are the benefits of using Cyasorb THT 4611?

Using Cyasorb THT 4611 in polymer formulations offers several benefits, including:

1. Superior UV protection: Cyasorb THT 4611 provides excellent protection against UV radiation-induced degradation, discoloration, and loss of physical properties. It is highly effective in preventing yellowing, cracking, and chalking of polymers due to UV radiation exposure.

2. Versatile: Cyasorb THT 4611 is a liquid HALS that is soluble in a wide range of solvents, including water. This makes it versatile and easy to incorporate into various polymer formulations.

3. High-performance: Cyasorb THT 4611 is a high-performance light stabilizer that provides long-lasting UV protection. It is resistant to leaching, migration, and extraction, ensuring that the polymer remains protected against UV radiation for an extended period.

4. Cost-effective: Using Cyasorb THT 4611 in polymer formulations can be cost-effective in the long run. Its excellent UV protection properties can extend the life of the polymer, reducing the need for frequent replacements.

How to use Cyasorb THT 4611?

Cyasorb THT 4611 is easy to incorporate into polymer formulations. It can be added to the polymer during the compounding process or as a masterbatch. The recommended dosage of Cyasorb THT 4611 varies depending on the polymer and the desired level of UV protection. Typically, a dosage of 0.2-1.0% is sufficient for most applications.

Conclusion

Cytec's Cyasorb THT 4611 is a high-performance light stabilizer that provides excellent protection against UV radiation-induced degradation, discoloration, and loss of physical properties. Its superior UV protection properties, versatility, and cost-effectiveness make it an ideal choice for manufacturers looking to protect their polymer products from the harmful effects of UV radiation.
