Flame Retardant Melamine Cyanurat

The flame retardant melamine cyanurate produced by Taixing adopts precise molecular ratio crystallization and silane coupling agent surface modification core technology to construct a stable layered hydrogen bond structure with a nitrogen content of ≥ 58.5%. It has a triple flame retardant mechanism of heat absorption, dilution, and carbonization, and can achieve UL 94 V-0 flame retardant with only 8% -22% addition, completely solving the industry problem of "high addition, low efficiency, and difficult compatibility" of traditional products, and providing a cost-effective halogen-free flame retardant solution for the global manufacturing industry.

Core strengths

1. Efficient and environmentally friendly flame retardant mechanism

·Gas phase dilution and cooling effect: A strong endothermic reaction occurs in the decomposition range of 300-400 ° C, absorbing a large amount of combustion heat and releasing non combustible gases such as nitrogen, ammonia, and water vapor, effectively diluting the concentration of oxygen and combustible gases in the flame zone and achieving "suffocation" fire extinguishing.

·Charcoal catalysis and barrier effect: The decomposition products can catalyze the dehydration and crosslinking of some polymer matrices (especially oxygen-containing polymers such as PA and PBT), forming an expanded, dense, and high-strength residual carbon layer. This carbon layer serves as an excellent thermal insulation barrier, protecting the underlying material from further thermal attacks.

·Environmentally friendly features: The combustion products are mainly non-toxic nitrogen, carbon dioxide, and water, non corrosive hydrogen halide gas, low smoke density, and fully comply with global green environmental regulations.

2. Excellent comprehensive material performance

·Excellent thermal stability and processing tolerance: The initial decomposition temperature is above 340 ° C, perfectly matching the processing temperature window of most engineering plastics (such as PA6, which is 260-280 ° C), ensuring that no premature decomposition occurs during the processing, avoiding the generation of bubbles or performance degradation.

·Excellent electrical performance: It has an extremely high volume resistivity (>10 ¹⁴Ω· cm), which can significantly improve the anti leakage trace index (CTI) of composite materials as a flame retardant filler, making it an ideal choice for electronic and electrical applications, ensuring its safety at 600V or even higher voltages.

·Balance between color stability and mechanical properties: Pure white appearance with minimal impact on product coloring, suitable for light or white products with color requirements. By optimizing surface treatment technology, the mechanical properties such as impact strength and tensile strength of the matrix resin can be maximally maintained.

3. Wide application compatibility

·Strong affinity with various polymers, especially with polyamide (PA6, PA66), thermoplastic polyester (PBT, PET), polyurethane (TPU), etc. It has excellent compatibility and can be uniformly dispersed through conventional mixing equipment.

·Excellent synergistic potential: It can produce good synergistic effects with flame retardants such as metal hydroxides (such as magnesium hydroxide), hypophosphates, polydimethylsiloxane, etc., while reducing the total addition amount, improving the flame retardant level and other properties.

Application field

1. Polyamide (nylon) halogen-free flame retardant

·Non reinforced PA6/PA66: Adding 10-14% MC-200 can achieve UL 94 V-0 (1.6mm) grade and maintain excellent mechanical properties and surface gloss. Suitable for electrical switches and small enclosures.

·Fiberglass reinforced PA: MC-300 (treated with a special silane coupling agent) is used in combination with a small amount of synergist (such as diethyl aluminum phosphate). In a 25-30% fiberglass filling system, adding 15-20% can meet the V-0 requirement and effectively improve the problem of CTI decrease caused by fiberglass exposure. Suitable for connectors, circuit breakers, etc.

2. Thermoplastic polyester

·PBT/PET and its glass fiber reinforced materials: The decomposition characteristics of MC match well with the processing temperature of PBT. Usually, adding 12-18% MC-200 in synergy with a small amount of polysiloxane can effectively suppress droplets, achieve V-0, and maintain good electrical and heat resistance.

3. Thermoplastic polyurethane (TPU)

·Halogen free flame-retardant TPU cable materials, films, and products: Adding 18-25% MC-100 or MC-200 can provide excellent flame retardancy to TPU while maintaining its good elasticity, wear resistance, and transparency (with a certain degree of haze).

4. Other polymers

·As a flame retardant filler in thermosetting plastics such as epoxy resin and unsaturated polyester; It can also be used for polyolefins (in combination with synergistic systems).
