In the chemical industry, CAS (Chemical Abstracts Service) numbers are vital for identifying chemical substances accurately. For professionals in material science, procurement, and product development, understanding specific CAS numbers and the compounds they represent is crucial. This article focuses on CAS 225789-38-8, which identifies Aluminum Diethylphosphinate (ADP), a significant player in the field of flame retardants. We will explore its properties, applications, and the importance of sourcing it from a reliable China-based manufacturer.

What is CAS 225789-38-8? Aluminum Diethylphosphinate (ADP) Explained

Aluminum Diethylphosphinate, often abbreviated as ADP, is an organophosphorus compound characterized by its aluminum center coordinated with diethylphosphinate groups. Its chemical formula is typically represented as C12H30AlO6P3, though variations exist depending on the exact stoichiometry and coordination. It is generally supplied as a white powder.

Key Properties and Chemical Characteristics

ADP possesses several properties that make it highly desirable in various industrial applications, particularly as a flame retardant:

  • High Phosphorus Content: The significant presence of phosphorus contributes to its flame retardant efficacy.
  • Thermal Stability: ADP exhibits excellent thermal stability, with decomposition temperatures often exceeding 350°C. This allows it to withstand the high processing temperatures common in engineering plastics.
  • Halogen-Free Nature: As a halogen-free compound, it offers environmental and safety benefits over traditional brominated or chlorinated flame retardants, producing less smoke and toxic byproducts during combustion.
  • Water Resistance: It shows good resistance to moisture, preventing issues like hydrolysis or reduced performance due to water absorption.
  • Good Dispersion: ADP can be effectively dispersed in various polymer matrices, ensuring uniform flame retardancy without significantly compromising the mechanical properties of the final product.

Applications of Aluminum Diethylphosphinate

The primary application for ADP is as a flame retardant additive, especially in polymers that require high performance and safety standards. It is widely used in:

  • Engineering Plastics: Particularly in polyamides (PA6, PA66), polyesters (PET, PBT), and polyurethanes (TPU), where it helps achieve UL 94 V-0 ratings.
  • Thermoset Resins: Enhancing the fire resistance of epoxy resins and other thermosets used in electrical insulation and structural components.
  • Electrical and Electronics (E&E): Components like connectors, switches, housings, and circuit board related materials benefit from ADP's flame retardancy.
