Flame retardant commonly used in wire and cable(2)

Third, magnesium hydroxide flame retardant
Advantages: application of magnesium hydroxide flame retardant (430 ° C decomposition) non-toxic
Disadvantages: Not resistant to acid, acetic acid can dissolve magnesium hydroxide, only suitable for low-end products. And it is extremely easy to get wet, the conductivity is not good, and the dispersion is poor.
Fourth, high heat resistant boehmite flame retardant
Advantages: 1% dehydration temperature is above 350 °C, dehydration at 500 °C reaches peak value, EC<50μS/cm, and dielectric property is strong, which solves the problem of product defects and dielectric properties caused by low dehydration temperature of aluminum hydroxide. Strong acidity and alkalinity.
Disadvantages: The flame retardancy is slightly lower than that of aluminum hydroxide, and it is necessary to increase the same flame retardant properties. However, its biggest feature is high heat resistance, thermal conductivity, acid and alkali resistance, and high heat resistance functional materials can increase the added value of the product.
