Formaldehyde Melamine Moulding Compound (MFMC) is a high-performance thermoset plastic. Its unique cross-linked structure and production process—precisely controlled polycondensation (molar ratio 1:2.5–3.5, pH 8.5–9.5) to form a 3D resin network, combined with spray-drying technology to produce free-flowing microspherical powder (50–150μm)—endow it with exceptional heat resistance (long-term 120°C), high surface hardness (3H pencil hardness), and flame retardancy (UL94 V-0). Enhanced by α-cellulose toughening and silane coupling agent surface treatment, MFMC achieves impact resistance and processability, making it ideal for melamine tableware (microwave-safe, food-grade), electrical insulation components (arc-resistant, dimensionally stable), automotive heat-resistant parts (oil/chemical-proof), and fire-retardant decorative panels (high-pressure lamination, wood/stone textures). Its low-formaldehyde formulations (≤0.5%) and eco-friendly processes (waste recycling) comply with international REACH/FDA standards, meeting the demand for high-performance, sustainable materials in consumer, industrial, and emerging sectors.
Formaldehyde melamine moulding compound, commonly known as melamine compound, is a polymer obtained by the reaction of melamine and formaldehyde. its main purpose is to make melamine tableware, a small amount for other products.
Melamine Tableware: Heat-resistant (120°C), food-grade safety (FDA), ideal for microwave-safe bowls and children’s dinnerware.
Electrical Insulation Parts: Flame retardant (UL94 V-0), arc-resistant, used in circuit breaker housings and switch sockets.
Automotive Heat-Resistant Components: Temperature tolerance (-40°C to 150°C), oil/chemical-proof, e.g., engine brackets and headlight bases.
Decorative Fireproof Panels: High-pressure lamination (HPL) technology with wood/stone textures for lab countertops and marine interiors.
Industrial Wear-Resistant Parts: High mechanical strength, chemical resistance, suitable for pump housings and tool handles.
Emerging Applications: Biocompatibility (ISO 10993) for medical trays and 3D-printed high-temperature prototypes.
Polycondensation and Drying:
Reaction endpoint controlled via viscosity (300–500 mPa·s) and flocculation precipitation tests.
Spray Drying: High-temperature (180–200°C) rapid powder formation yields microspherical particles (50–150 μm) with excellent flowability.
Modification Processes:
Addition of α-cellulose (10–20%) for toughening and zinc stearate (0.5–1%) as a lubricant to prevent mold sticking.
Surface treatment with silane coupling agents enhances interfacial adhesion.
Safety and Sustainability:
Strict control of free formaldehyde (≤0.5%) and migration limits (≤1.5 mg/dm²), compliant with food-contact standards.
Dust control (bag filters) and formaldehyde recovery (condensation and reuse).
Core Advantages
Efficient Molding:
High powder flowability enables complex mold filling and short molding cycles (140–160°C, 20–30 MPa).
Product Performance:
High surface gloss (mirror finish for tableware), arc resistance (electrical components), and heat resistance.
Cost Efficiency:
Recycled waste powder (≤15% blended with new powder) reduces material waste.
Application Flexibility:
Compatible with functional fillers (glass fibers, wood flour) for diverse uses in electronics, décor, and consumer goods.
