    Melamine CAS 108-78-1

    Melamine (CAS 108-78-1) is an organic base and trimer of cyanamide functioning as a primary feedstock in the production of thermosetting resins and durable laminates. Chemically identified as 1,3,5-Triazine-2,4,6-triamine or Cyanurotriamide, this white crystalline powder acts to impart heat resistance and structural integrity to molded plastics and adhesives. As a high-nitrogen Heterocyclic amine, it is extensively polymerized with formaldehyde to create melamine-formaldehyde resins used in decorative surfaces, dinnerware, and flame-retardant foams. We ensure bulk supply capabilities for this material, providing access to competitive factory pricing and customized specifications to meet specific particle size and purity needs. Full technical documentation, including MSDS, TDS, COA, is available to support compliance and safety protocols.

    Product Description

    Melamine is synthesized from urea. When reacted with formaldehyde, it forms Melamine-Formaldehyde resin, a very durable thermosetting plastic.

    Key Features:

    • High Purity: Our standard production guarantees a minimum purity of 99.8%, ensuring consistent reaction rates in resin production.
    • Thermosetting: Products made with Melamine are hard, scratch-resistant, and retain their shape under heat.
    • Flame Retardancy: Due to its nitrogen-rich structure, it releases nitrogen gas when burned, which extinguishes flames, making it a key additive in fire-retardant foams and coatings.
    • Chemical Resistance: Provides excellent resistance to chemical corrosion in finished coatings and laminates.

    Applications

    1. Laminates: Used in the production of High-Pressure Laminates (HPL) for flooring, furniture, and kitchen cabinets due to its high hardness and scratch resistance.
    2. Wood Adhesives: Reacted to form Melamine-Urea-Formaldehyde (MUF) resins, used as waterproof adhesives in plywood, particleboard, and MDF manufacturing.
    3. Molding Compounds: Used to make melamine dinnerware (plates, bowls) which are durable, heat-resistant, and non-breakable.
    4. Coatings: Used as a cross-linking agent in baked enamels and automotive coatings (HMMM series) to improve gloss and durability.
    5. Concrete Admixtures: Used to produce Sulfonated Melamine Formaldehyde (SMF), a high-range water reducer (superplasticizer) for high-strength concrete.
    6. Textile & Paper: Used as a finishing agent to provide wrinkle resistance and water repellency.

    Storage Conditions

    • Environment: Store in a cool, dry, and well-ventilated warehouse.
    • Humidity: Critical. Keep away from moisture. Melamine powder can cake or clump if exposed to high humidity.
    • Separation: Store separately from oxidants and strong acids. Do not mix storage.
    • Packaging: Keep bags sealed when not in use.
    • Shelf Life: 12-24 months under proper storage conditions.

    Safety Precautions

    • Industrial Use Only: This product is strictly for industrial applications. Do not use in food or feed processing.
    • Inhalation: Melamine dust may cause irritation to the respiratory tract. Use local exhaust ventilation and wear a dust mask (N95 or equivalent) during handling.
    • Skin/Eye Contact: May cause mechanical irritation. Wear protective gloves and safety goggles. Wash thoroughly with soap and water after handling.
    • Fire: Not combustible, but decomposes upon heating to produce toxic fumes (cyanide, nitrogen oxides).
