Songsorb CS 928: A Reliable Light Stabilizer for Diverse Applications
As the demand for high-performance materials increases, the need for effective stabilizers and additives also rises. Among the most critical factors that affect the durability and longevity of materials is exposure to UV radiation. UV rays can cause significant damage to plastics, coatings, and other materials, leading to discoloration, degradation, and loss of mechanical properties. To combat this problem, manufacturers turn to UV stabilizers, which can absorb or reflect UV radiation and prevent its harmful effects. One of the most popular and reliable UV stabilizers in the market is Songsorb CS 928.
Songsorb CS 928 is a benzotriazole-based UV absorber that belongs to the family of hindered amine light stabilizers (HALS). It is a white or off-white powder with a molecular weight of 530.8 g/mol and a melting point of 127-132°C. Songsorb CS 928 has a high degree of solubility in organic solvents and is compatible with a wide range of polymers, including polyolefins, PVC, PS, ABS, and PET. Its main function is to absorb UV radiation in the 300-400 nm range, which is the most damaging to materials.
Songsorb CS 928 provides various benefits to materials, depending on the application and the polymer matrix. Some of the most significant advantages of Songsorb CS 928 are:
- Excellent UV absorption: Songsorb CS 928 has a high extinction coefficient in the UV region, which means it can absorb a significant amount of UV radiation and convert it into harmless heat. This property helps prevent yellowing, cracking, and chalking of materials exposed to sunlight.
- Low volatility: Songsorb CS 928 has a low vapor pressure and does not evaporate or migrate easily from the polymer matrix. This feature ensures that its UV protection remains stable and long-lasting.
- Synergistic effect: Songsorb CS 928 can work in combination with other stabilizers, such as antioxidants and HALS, to boost the overall performance of the material. This synergy can enhance the resistance of the material to weathering, oxidation, and heat aging.
- FDA compliance: Songsorb CS 928 is approved by the FDA for food contact applications, making it suitable for use in packaging and containers that come into direct contact with food.
Songsorb CS 928 has a broad range of applications, from outdoor products to indoor items. Some of the most common uses of Songsorb CS 928 are:
- Automotive parts: Songsorb CS 928 is widely used in the automotive industry to protect the exterior and interior parts of vehicles from UV radiation. It can prevent fading, cracking, and discoloration of bumpers, dashboards, and door panels.
- Building materials: Songsorb CS 928 is added to PVC window profiles, roofing membranes, and siding to prevent degradation and loss of transparency. It can also improve the weatherability of sealants and adhesives used in construction.
- Packaging: Songsorb CS 928 is used in food packaging films, containers, and closures to ensure that the food remains fresh and safe. It can prevent the oxidation and rancidity of fats and oils in food products.
- Personal care products: Songsorb CS 928 is added to cosmetics, sunscreens, and hair care products to protect them from UV radiation. It can prevent the degradation of colors, fragrances, and active ingredients in these formulations.
In conclusion, Songsorb CS 928 is a versatile and effective UV stabilizer that can enhance the durability and quality of a wide range of materials. Its excellent UV absorption, low volatility, synergistic effect, and FDA compliance make it a preferred choice for many industries.
