UV-312: A Versatile Ultraviolet Absorber for Effective Protection of Polymers

In the world of polymer chemistry, ultraviolet (UV) radiation is a major cause of degradation, leading to loss of strength, discoloration, and other undesirable effects. To combat this issue, various types of additives are used to protect polymers from UV radiation. One such additive is UV-312, also known as BASF TINUVIN 312, SONGWON SABO®STAB UV 312, and Matsubara UV 312, among others. INNO SPECIALTY CHEMICALS is a leading manufacturer and supplier of UV-312 from China, providing high-quality and cost-effective solutions for polymer protection.

UV-312 belongs to the class of benzophenone-based UV absorbers, which are widely used in various polymers, including polyethylene, polypropylene, polycarbonate, and others. The main function of UV-312 is to absorb the harmful UV radiation and convert it into harmless heat, thereby preventing polymer degradation. UV-312 has a broad absorption spectrum, ranging from 270 to 380 nm, which makes it effective against both UVA and UVB radiation. Moreover, UV-312 has good compatibility with various polymers and other additives, making it a versatile choice for polymer protection.

One of the key advantages of UV-312 is its high thermal stability, which allows it to withstand the high processing temperatures of polymers without degradation. This is particularly important for polymer applications that involve high-temperature processing, such as injection molding, extrusion, and blow molding. UV-312 also has good light stability, meaning that it does not degrade over time under prolonged exposure to UV radiation. This makes it a reliable choice for long-term polymer protection.

UV-312 is typically used in concentrations ranging from 0.1% to 2% by weight, depending on the polymer and the desired level of UV protection. The exact dosage should be determined by the polymer manufacturer or compounder based on the specific application requirements. UV-312 is usually added to the polymer in the form of a masterbatch or a concentrate, which simplifies the handling and dosing process.

UV-312 has many applications in various industries, including packaging, automotive, construction, and agriculture. In packaging, UV-312 is used to protect food and beverage containers from UV radiation, which can cause discoloration and spoilage. In automotive applications, UV-312 is used to protect exterior parts from fading and cracking due to UV radiation. In construction, UV-312 is used to protect building materials from UV radiation, which can cause discoloration and degradation. In agriculture, UV-312 is used to protect greenhouse films and crop covers from UV radiation, which can reduce their lifespan.

In conclusion, UV-312 is a versatile and effective ultraviolet absorber that provides reliable protection for polymers against UV radiation. INNO SPECIALTY CHEMICALS is a leading manufacturer and supplier of UV-312 from China, offering high-quality and cost-effective solutions for polymer protection. With its broad absorption spectrum, high thermal stability, and good compatibility with various polymers, UV-312 is an ideal choice for a wide range of applications in various industries.
