UV Absorber 1164

Product Overview

UV Absorber 1164 represents a class of advanced hindered amine and triazine-based light stabilizers engineered for demanding industrial applications. Identified by CAS number 2725-22-6, this chemical compound serves as a critical additive in the preservation of polymer integrity against ultraviolet radiation. Our manufacturing process ensures high purity levels, making it an ideal choice for producers seeking long-term durability in plastic products exposed to harsh environmental conditions.

The molecular structure of this absorber allows for efficient energy dissipation, converting harmful UV radiation into harmless thermal energy. This mechanism significantly reduces the rate of photo-oxidative degradation, thereby extending the service life of materials such as polyolefins and engineering plastics. As a leading supplier in the speciality chemicals sector, we guarantee consistent quality across all batches.

Key Technical Advantages

• Broad-spectrum protection with strong absorption peaks in both UVA and UVB regions, specifically at 342nm and 293nm.
• Exceptionally low volatility ensures the additive remains within the polymer matrix during high-temperature processing.
• High inherent light stability provides prolonged protection compared to conventional stabilizers.
• Superior compatibility with most polyolefins and engineering polymers prevents blooming or exudation.
• Thermal stability supports processing in high-temperature applications without decomposition.

Technical Specifications

Quality control is paramount in our production facility. Each batch undergoes rigorous testing to meet international standards. The following table outlines the typical physical and chemical characteristics of our UV Absorber 1164.

Industrial Applications

This UV absorber is versatile and suitable for a wide range of polymer systems. It is highly recommended for use in polyethylene (PE) films, tapes, and sheets, including metallocene catalyzed grades. In polypropylene (PP) applications, it protects fibers, tapes, and thermoplastic olefins (TPO) from yellowing and brittleness.

Furthermore, it demonstrates excellent performance in engineering plastics such as polyacetal, polyamides, and polycarbonate (PC) capstock or general-purpose grades. It is also compatible with polyesters like PET and PBT, as well as styrenic polymers including ASA, ABS, and PMMA. This broad compatibility makes it a valuable asset for formulators seeking a single solution for multiple product lines.

Storage and Handling

To maintain optimal quality, containers should be kept tightly closed when not in use. The product must be stored in a cool, dry place away from direct sunlight and moisture. Proper handling procedures ensure safety and prevent contamination. We provide comprehensive documentation, including Certificates of Analysis (COA), with every shipment to verify compliance with specified parameters.
