For procurement managers and R&D professionals in the chemical and materials industries, selecting the right additives is critical for product performance and market competitiveness. UV Absorber UV-360 (CAS: 103597-45-1), also known as Bisoctrizole, is a highly sought-after additive for its exceptional ability to protect materials from UV radiation damage. This guide aims to provide insights into purchasing UV-360, focusing on specifications, applications, and how to identify a reliable manufacturer and supplier, particularly from China.

What is UV Absorber UV-360?

UV Absorber UV-360 is a benzotriazole-based organic compound. Its primary function is to absorb harmful ultraviolet radiation, typically in the 300-400 nm wavelength range, and convert it into thermal energy. This process shields polymers, coatings, and other susceptible materials from photodegradation, which can cause discoloration, loss of mechanical strength, and embrittlement.

Key characteristics that make UV-360 a preferred choice include:

• High UV Absorption Efficiency: Excellent performance across the UV spectrum.
• Low Volatility: Crucial for high-temperature processing, ensuring additive retention.
• Excellent Photostability: Resists degradation itself, providing long-term protection.
• Broad Compatibility: Works well with a wide range of polymers, including polycarbonates, polyesters, polyamides, and polyolefins.

The chemical formula is C41H50N6O2, with CAS number 103597-45-1.

Key Specifications to Look For When Buying

When you decide to buy UV absorber UV-360 in China, it’s essential to ensure the product meets your quality requirements. Here are critical specifications to inquire about:

• Purity: Look for high purity, typically 97% min or higher (e.g., ≥99% by HPLC). Higher purity ensures better performance and fewer undesirable side reactions.
• Appearance: Usually described as a white to light yellow powder.
• Melting Point: A narrow melting range (e.g., 195-199 °C) indicates good purity.
• Solubility: Check solubility in common organic solvents relevant to your formulation (e.g., chloroform, toluene).
• Volatile Content: Ensure low loss on drying or volatile content, confirming its low volatility.
• Ash Content: Typically very low (≤0.1%), indicating minimal inorganic impurities.

Common Applications Requiring UV-360

UV Absorber UV-360 is indispensable in applications where materials are exposed to UV radiation and/or high processing temperatures:

• Plastics: Automotive parts, construction materials, outdoor furniture, electronic housings, agricultural films.
• Coatings: Automotive paints, industrial coatings, wood finishes, architectural paints.
• Adhesives and Sealants: For outdoor applications or products exposed to sunlight.
• Fibers and Textiles: Synthetic fibers for outdoor use, upholstery, and performance apparel.

Finding a Reliable Manufacturer and Supplier

To ensure product quality and supply chain reliability, selecting the right partner is paramount. As a dedicated UV absorber UV-360 manufacturer, we recommend the following when sourcing:

• Verify Certifications: Look for ISO certifications or other quality management system compliance.
• Request Samples: Always obtain samples for in-house testing to confirm performance and compatibility.
• Check Technical Data Sheets (TDS) and Safety Data Sheets (SDS): Ensure these documents are comprehensive and readily available.
• Inquire about Pricing and MOQ: Understand the cost per kilogram and any minimum order quantities (MOQ). A competitive UV stabilizer for polycarbonate price from a reliable source is key.
• Assess Supplier Reputation: Look for established suppliers with good track records and positive customer feedback. A reputable high purity bisoctrizole manufacturer will be transparent about their processes.

By following these guidelines, procurement professionals can confidently source UV Absorber UV-360, ensuring their products are well-protected against UV damage and maintain their integrity and market appeal. When you need to buy UV absorber UV-360, choose a partner committed to quality and reliability.
