In the complex world of chemical procurement, understanding product identifiers like CAS numbers is crucial for efficient sourcing and application. CAS Number 106214-84-0 refers to Aminopropyl Terminated Polydimethylsiloxane, a functional silicone fluid widely used across various industrial sectors. For procurement managers and R&D scientists, a clear grasp of this chemical's identity, properties, and sourcing channels is paramount.

Aminopropyl Terminated Polydimethylsiloxane (PDMS) is a polymer characterized by a flexible siloxane backbone and terminating primary amine groups. The CAS number 106214-84-0 uniquely identifies this specific chemical compound. Its chemical structure, H₂N(CH₂)₃Si(CH₃)₂O[Si(CH₃)₂O]nSi(CH₃)₂(CH₂)₃NH₂, highlights the presence of reactive amino propyl groups at both ends of the polydimethylsiloxane chain. This structural feature is key to its diverse applications.

The physical properties of this silicone fluid typically include being a colorless to transparent liquid. Its viscosity can vary depending on the degree of polymerization, influencing its handling and application characteristics. The presence of amino groups imbues it with a certain polarity and reactivity, differentiating it from inert silicone oils. Understanding these properties is essential for formulators when considering its use as a reactive modifier, paint additive, or mold release agent.

For procurement professionals, identifying reliable sources for chemicals with specific CAS numbers is a core responsibility. When looking to buy Aminopropyl Terminated Polydimethylsiloxane, it's advisable to work with established manufacturers and suppliers, particularly those with a strong presence in regions like China, known for its robust chemical manufacturing capabilities. These suppliers often provide competitive prices and a wide range of product specifications to meet diverse industrial needs.

The key advantage of this chemical lies in its dual functionality: the inertness and flexibility of the silicone backbone combined with the reactivity of the amine end groups. This allows it to be used in applications where adhesion, cross-linking, or surface modification is required. For example, in the coatings industry, it can improve substrate adhesion and surface slip. In textiles, it acts as a softening agent, and in molding operations, it serves as an effective release agent.

When initiating a purchase, procurement specialists should always request detailed technical data sheets (TDS) and safety data sheets (SDS) for CAS 106214-84-0. These documents provide critical information regarding physical and chemical properties, hazard identification, safe handling procedures, and environmental impact. Furthermore, clarifying minimum order quantities (MOQ) and lead times with the supplier is crucial for effective supply chain management.

In conclusion, understanding CAS 106214-84-0, Aminopropyl Terminated Polydimethylsiloxane, is fundamental for chemical procurement and R&D. By focusing on reliable suppliers and thoroughly reviewing product specifications, businesses can effectively source this versatile silicone fluid to enhance their product formulations and manufacturing processes.
