As we all know, UV rays can cause irreversible damage to materials, shorten their lifespan, and alter their physical properties. That's why it's crucial to protect your products from the harmful effects of UV exposure. Fortunately, there's a solution that can help you achieve that: UV-770, a light stabilizer that can effectively absorb UV radiation, prevent degradation, and extend the durability of your products. In this article, we'll introduce you to UV-770, its features, benefits, and applications, and tell you why it's the best choice for your UV protection needs.
What is UV-770?
UV-770, also known as BASF light stabilizer TINUVIN 770, is a bis(2,2,6,6-tetramethyl-4-piperidinyl) sebacate-based light stabilizer that belongs to the hindered amine light stabilizer (HALS) family. HALS are organic compounds that can scavenge free radicals, prevent oxidative degradation, and enhance the photostability of materials. UV-770 is a white to light yellow powder with a molecular weight of 480.8 g/mol and a melting point of 110-120°C. It's soluble in organic solvents such as methanol, ethanol, acetone, and benzene, but insoluble in water.
UV-770 is produced by Ningbo Inno Pharmchem Co., Ltd., a leading supplier of high-quality light stabilizers, UV absorbers, antioxidants, and other specialty chemicals. With more than ten years of experience in the field, Inno Pharmchem has established itself as a reliable manufacturer that provides customized solutions, competitive prices, and excellent customer service.
What are the features and benefits of UV-770?
UV-770 has several features and benefits that make it a versatile and effective UV absorber for various applications. Here are some of them:
1. High thermal stability: UV-770 can withstand high temperatures and remain active in polymer matrices without decomposition or sublimation. It has a decomposition temperature of 270°C and a sublimation pressure of 2.21E-7Pa at 25°C.
2. Low volatility: UV-770 has low vapor pressure and low volatility, which means it won't evaporate or migrate from the polymer matrix over time. This ensures long-lasting UV protection and prevents yellowing, cracking, or delamination.
3. Non-discoloring: UV-770 is a non-staining and non-discoloring light stabilizer that won't affect the color or transparency of the substrate. It can be used in clear, white, or colored materials without affecting their appearance or performance.
4. Synergistic effect: UV-770 can be used in combination with other light stabilizers, UV absorbers, or antioxidants to enhance their performance and provide a synergistic effect. This means that you can tailor your UV protection system to your specific needs and achieve optimal results.
5. Broad application range: UV-770 can be used in various polymers, including polyolefins, PVC, polyurethanes, polyesters, and others. It's suitable for outdoor and indoor applications and can provide excellent protection against weathering, aging, and yellowing.
What are the applications of UV-770?
UV-770 can be used in a wide range of applications that require UV protection and long-term durability. Here are some examples:
1. Packaging: UV-770 can be used in food packaging films, containers, and bottles to prevent UV degradation of the contents, maintain their quality and freshness, and extend their shelf life.
2. Building and construction: UV-770 can be used in roofing membranes, window profiles, siding, and other building materials to prevent discoloration, cracking, or deformation caused by UV exposure and weathering.
3. Automotive: UV-770 can be used in automotive parts such as dashboards, door panels, and exterior trims to prevent fading, cracking, or peeling caused by UV exposure and heat.
4. Textiles and fibers: UV-770 can be used in synthetic fibers, fabrics, and carpets to prevent fading, yellowing, or loss of strength caused by UV exposure and washing.
5. Adhesives and sealants: UV-770 can be used in adhesives and sealants to prevent yellowing, cracking, or loss of adhesion caused by UV exposure and aging.
Conclusion
UV-770 is a versatile and effective light stabilizer that can provide long-lasting UV protection and enhance the durability of your products. It has high thermal stability, low volatility, non-discoloring, and a synergistic effect that makes it suitable for various applications in different industries. As a product of Ningbo Inno Pharmchem Co., Ltd., UV-770 is produced by a reliable and experienced manufacturer that can provide customized solutions and excellent customer service. If you're looking for a UV absorber that can meet your UV protection needs, UV-770 is the best choice for you.
