UV Absorber UV-234

Product Overview

UV Absorber UV-234 represents a premium class of benzotriazole-type ultraviolet light stabilizers designed for high-performance polymer applications. This advanced chemical additive is engineered to protect susceptible materials from photodegradation caused by prolonged exposure to sunlight and artificial UV sources. By effectively absorbing harmful ultraviolet radiation and dissipating it as harmless thermal energy, this product significantly extends the service life and maintains the aesthetic integrity of finished goods. Our manufacturing process ensures a purity level that meets or exceeds global industry standards, making it a reliable drop-in replacement for established benchmarks in the market.

Manufactured under strict quality control protocols, this light stabilizer is particularly valued for its exceptional thermal stability. This characteristic allows it to withstand rigorous processing conditions without decomposing or losing efficacy, which is critical for high-temperature polymer manufacturing. Whether used in engineering plastics or protective coatings, UV-234 provides consistent performance batch after batch, ensuring that your final products remain robust against environmental stressors.

Technical Specifications

Quality assurance is paramount in chemical manufacturing. The following table outlines the key physical and chemical parameters that define the standard grade of this product. Each batch is accompanied by a Certificate of Analysis to verify compliance with these specifications.

Industrial Applications

The versatility of UV Absorber UV-234 makes it an essential component in a wide array of polymer formulations. It is highly effective for polymers that require processing at elevated temperatures where lesser stabilizers might fail. Key application areas include polycarbonates, polyesters, and polyacetals, where clarity and durability are non-negotiable. Additionally, it is extensively used in polyamides, polyphenylene sulfides, and polyphenylene oxides to prevent yellowing and mechanical property loss.

• Ideal for aromatic copolymers and thermoplastic polyurethane systems.
• Enhances the longevity of polyurethane fibers and polyvinyl chloride products.
• Compatible with styrene monomers and various copolymer blends.
• Suitable for manufacturing molds, films, sheets, and synthetic fibers.
• Provides superior protection for automotive coatings and industrial finishes.

Formulators appreciate this product for its ability to maintain high transmittance values, ensuring that the final product does not suffer from unwanted coloration while still receiving maximum UV protection. This balance is crucial for applications where visual appearance is as important as structural integrity.

Storage and Handling

To maintain the optimal quality of this light stabilizer, proper storage conditions must be observed. The product should be kept in a sealed, dry environment away from direct sunlight and sources of high heat or humidity. It is critical to avoid storage near light stabilizers containing sulfur or halogen elements, as cross-contamination could affect performance. The standard packaging consists of cardboard drums lined with plastic bags, with a net weight of 25kg per unit. This packaging ensures protection during transit and storage. As a non-dangerous good, it can be shipped via standard logistics channels, though local regulations should always be consulted. For bulk orders, comprehensive technical data sheets and safety documentation are available upon request to facilitate seamless integration into your supply chain.
