Description

Aluminum Phenylphosphinate is an organophosphorus compound that serves as a highly effective flame retardant and smoke suppressant. This material is particularly valued for its ability to enhance the fire safety of polymer composites without significantly compromising their physical properties. It is a critical additive for manufacturers in the plastics, textiles, and coatings industries seeking to meet stringent international fire safety regulations.

Application

• Primary flame retardant and smoke suppressant in engineering thermoplastics like polyamides (PA), polyesters (PBT, PET), and polyolefins.
• Key additive in fire-resistant coatings and intumescent paints for construction materials and electrical cables.
• Used in the formulation of fire-retardant synthetic fibers and textiles for protective clothing and home furnishings.
• Component in epoxy resin systems and unsaturated polyesters for electronic encapsulants and circuit boards.
• Synergistic agent combined with other nitrogen-based flame retardants to enhance efficacy and reduce loading levels.
• Applied in the production of thermoplastic elastomers (TPE) and wire & cable compounds.

Quality Control

Our Aluminum Phenylphosphinate is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure consistent performance as a flame retardant, including analysis of key parameters like phosphorus content, particle size distribution, and thermal stability. Certificates of Analysis (COA) documenting purity and specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and should be stored in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent absorption of moisture from the air, which can affect performance.
