CAS 9002-98-6 PEI Purity 98% MW 10000/ 25000 Branched Polyethylenimine For Speciality Chemicals

 

Product Description

Polyethylenimine (PEI)

Description:
Polyethylenimine (PEI) is a polymer with repeating units of the amine group (-NH2) and is commonly used in various applications due to its unique properties. PEI is available in different molecular weights and forms, such as linear or branched structures.

 

Technical Data Sheet:

• Chemical Formula: (C2H5N)n
• Appearance: Colorless to pale yellow liquid
• Solubility: Highly soluble in water and common organic solvents
• Molecular Weight: Varies depending on the specific type of PEI
• CAS Number: 9002-98-6

Features:

1. Cationic Nature: PEI is highly cationic, meaning it carries a positive charge due to the presence of amino groups. This property makes it useful in various applications, including as a polyelectrolyte and a gene transfection agent.

2. Versatility: PEI is a versatile polymer with applications in adhesives, coatings, flocculants, and as a component in various formulations due to its ability to interact with a wide range of compounds.

3. Film-Forming Properties: Some forms of PEI can create films with good adhesion properties, making them suitable for coating applications.

4. Gene Delivery: Branched PEI, in particular, is widely used in gene therapy and transfection studies due to its high transfection efficiency and ability to condense and protect DNA.

Applications:

1. Gene Delivery: PEI is extensively used in gene therapy and genetic research as a transfection agent to deliver nucleic acids, such as DNA and RNA, into cells for various biomedical applications.

2. Coatings and Adhesives: PEI can be used in coatings to improve adhesion and as a cross-linking agent. It is also employed in adhesives for bonding various materials.

3. Water Treatment: PEI is used in water treatment processes as a flocculant to remove impurities and particles from water by aggregating them for easier removal.

4. Paper Industry: In the paper industry, PEI is utilized as a wet-strength resin, enhancing the strength and durability of paper products.

5. Textile Industry: PEI can be employed in the textile industry for various applications, such as dye fixing and as a sizing agent.

6. Biomedical Applications: Apart from gene delivery, PEI is used in various biomedical applications, such as tissue engineering, drug delivery systems, and as a component in medical devices.
