Understanding CAS 131-54-4: The Chemical Profile

CAS 131-54-4 is a benzophenone derivative recognized for its potent UV-absorbing capabilities. Its molecular structure allows it to effectively absorb ultraviolet light, particularly in the UV-A and UV-B spectrums, converting this energy into harmless heat. This mechanism is fundamental to its role as a photostabilizer. The compound typically presents as a light yellow powder with a high purity assay, often exceeding 99%, which is crucial for consistent performance in demanding applications.

Key Properties for Industrial Applications

• UV Absorption: Effectively absorbs UV light below 380nm.
• Appearance: Light yellow powder.
• Purity: Typically ≥99%, ensuring reliable performance.
• Melting Point: Around 134°C, indicating good thermal stability for processing.
• Compatibility: Demonstrates excellent compatibility with a broad range of polymers and resins.

Diverse Applications for a Versatile UV Absorber

The versatility of CAS 131-54-4 makes it a sought-after ingredient across multiple sectors. When considering its applications, think about where UV degradation is a concern:

• Plastics Industry: Essential for protecting polymers like PVC, acrylic resins, polycarbonates, and polyurethanes from photodegradation. It helps maintain mechanical properties, prevents yellowing, and extends the service life of plastic products exposed to sunlight. Businesses looking to purchase UV stabilizers for plastics will find this compound highly effective.
• Coatings and Paints: Incorporated into formulations for paints, varnishes, and industrial coatings to prevent color fading, chalking, and loss of gloss. This is critical for automotive finishes, architectural coatings, and protective layers. Sourcing this from a reputable UV absorber manufacturer in China ensures high quality for your coating formulations.
• Resin Systems: Used in epoxy resins, phenolic resins, and nitrocellulose to enhance their resistance to UV light, thereby preserving their structural integrity and appearance in various composite and adhesive applications.
• Cosmetics and Personal Care: While primarily used in industrial settings, its UV filtering properties also lend themselves to certain cosmetic applications for sun protection.

Sourcing CAS 131-54-4 from China: What to Look For

For businesses seeking to buy UV absorber CAS 131-54-4, China offers a robust manufacturing base. However, it's crucial to partner with a reliable supplier. When evaluating potential manufacturers, consider:

• Purity and Quality Control: Ensure the supplier provides clear specifications and Certificates of Analysis (CoA) confirming the ≥99% assay.
• Production Capacity and Reliability: For bulk orders, the manufacturer's capacity to meet demand consistently is vital.
• Technical Support: A good supplier offers technical data and support to assist with formulation challenges.
• Pricing and Logistics: Compare pricing while considering shipping costs and lead times. Getting a clear UV absorber price quote is essential for budgeting.
