    Polyethylene Polyamine CAS 68131-73-7

    Polyethylene Polyamine CAS 68131-73-7 is a complex mixture of ethyleneamines utilized as a cost-effective precursor in the formulation of industrial hardeners and additives. Often referred to commercially as PEPA, this higher boiling amine blend serves as a versatile backbone for synthesizing polyamide resins, fuel additives, and cationic surfactants used in asphalt emulsification. The material, known technically as amines, polyethylenepolyamines, provides reactive amine hydrogens essential for crosslinking reactions in epoxy systems and wet-strength resins for paper production. We provide competitive factory pricing and flexible options for customized specifications regarding viscosity and amine value. Our bulk supply is supported by comprehensive safety and technical documentation, including MSDS, TDS, COA, ensuring compliant industrial usage.

    Applications

    Our Polyethylene Polyamine is engineered to meet the rigorous demands of various downstream industries:

    Industrial & Chemical Manufacturing

    • Epoxy Curing Agents: Acts as a highly effective cross-linking agent and hardener for epoxy resins used in coatings, adhesives, and floorings.
    • Paper Industry: Used in the synthesis of wet-strength resins (PAE resins) to improve the durability of paper products.
    • Fuel & Oil Additives: Serves as a dispersant and ashless detergent in lubricating oils and fuel systems.

    Water Treatment

    • Chelating Agents: Due to its polyamine structure, it effectively chelates heavy metal ions, making it suitable for wastewater treatment and sludge dewatering applications.

    Research & Synthesis

    • Chemical Intermediates: Utilized in the synthesis of surfactants, corrosion inhibitors, and textile auxiliaries.

    Quality Assurance (QA/QC)

    At Industrochem, quality is not just a promise; it is a quantified standard. Our manufacturing partners operate under strictly controlled GMP-compliant environments and ISO 9001:2015 management systems.

    • Batch Consistency: Every batch undergoes rigorous testing using Gas Chromatography (GC) for composition analysis and titration methods for amine value verification.
    • Traceability: We maintain full lot traceability from raw material intake to final packaging.
    • Pre-Shipment Inspection: We support third-party testing (SGS/BV) upon request to ensure the cargo meets your specific requirements before it leaves the port.

    Storage & Safety

    Storage Conditions

    • Store in a cool, dry, and well-ventilated area, away from direct sunlight and heat sources.
    • Keep containers tightly closed to prevent moisture absorption (hygroscopic) and reaction with carbon dioxide in the air.
    • Incompatible with strong acids, oxidizing agents, and halogenated hydrocarbons.

    Safety Handling & PPE

    PEPA is classified as corrosive. Strict adherence to safety protocols is required:

    • Respiratory Protection: Use a NIOSH/MSHA-approved respirator if ventilation is inadequate.
    • Eye Protection: Chemical safety goggles and a face shield are mandatory to prevent eye damage.
    • Skin Protection: Wear chemical-resistant gloves (Butyl rubber or Neoprene) and protective clothing.
    • Emergency: In case of contact with eyes, rinse immediately with plenty of water for at least 15 minutes and seek medical advice.

    FAQ - Technical & Supply Chain

    • Q:

      Is this material suitable for manufacturing epoxy curing agents?

      A: This product is widely applied in the synthesis of polyamide curing agents and adducts, where its mixture of amine functionalities provides tailored crosslinking density for industrial coatings and adhesives.
    • Q:

      Does this CAS number correspond to the mixed amine stream known as PEPA?

      A: Yes, CAS 68131-73-7 specifically identifies Polyethylene Polyamine, a complex mixture of linear, branched, and cyclic ethyleneamines typically used when a specific single-component amine is not required.
    • Q:

      Is polyethylene polyamine used at the formulation level in epoxy systems?

      A: Yes. Polyethylene polyamine is typically applied as a reactive component in epoxy curing systems, where amine functionality participates in crosslinking reactions during formulation and processing.
