Melamine cyanurate (MCA flame retardant) is a white crystalline powder with a greasy feeling, and is a nitrogen-based halogen-free flame retardant with excellent performance.This product is mainly used as a halogen-free flame retardant in synthetic resins, synthetic rubbers, and plastic products; as a solid lubricant additive in lubricating oils and greases; as a flame-retardant and matting aid in fire-resistant coatings; in cosmetics Used as a lubricant.MCA flame retardant is especially suitable for PA6 and PA66 without filler, and its flame retardant performance is very ideal.The modified MCA-1 and MCA-2 developed by our company and Sichuan University can reach the UL94-V0 flame retardant level in flame retardant PA6 and PA66. The electronic grade MCA flame retardant has high purity and no impurities. It is used in epoxy products for electronic products. The resin has been popularized and applied; the self-developed MG-3 makes the flame retardant grade of silica gel reach UL94-V0, and has less influence on the mechanical properties of materials than traditional metal oxide flame retardants.
Specifications and indicators of flame retardant synergist are as follows: Project indicators Appearance white or light yellow crystalline powder Purity 98.0 MIN Melting point (°C) 115--120°C Drying weight loss 0.5% MAX Mechanism of action: Plastics break bonds to generate free radicals at high temperature or when burning In order to be more conducive to combustion, the synergist also breaks bonds and combines with polymer free radicals. Under certain conditions, it is easy to form free radicals with high stability, and dripping takes away heat, thereby preventing combustion.The flame retardant mechanism of different systems is different.Product use: LN FR -038 is widely used in the flame retardant synergy of PP, PE, XPS, HIPS and other polymer materials.It has little effect on the tensile strength of the polymer system, taking into account the tensile properties and flame retardant properties, and considering the cost factor, the recommended dosage is 0.15%-0.2%, and the overall dosage of flame retardants can be reduced by 15%-25%.Typical application: such as adding 1.6% iodobenzene and 0.
