Power cable flame retardant mainly in the following four:

1. Antimony flame retardant

Advantages: antimony trioxide can not be alone as a flame retardant, and with the appropriate combination of halogen compounds can play a particularly effective flame retardant properties. Antimony flame retardant synergistic shortcomings: heavy metals, toxic, and arsenic homologues, crude products generally contain arsenic and other heavy metals, arsenic trioxide is arsenic. Can not be used as a green filler and green flame retardant.

2. Aluminum hydroxide flame retardant (ATH)

Advantages: low price, good flame resistance.

Disadvantages: poor heat resistance, 200 ℃ that began to dehydration, 330 ℃ to 350 ℃ that is completely dehydrated, and resin curing in the aluminum hydroxide dehydration temperature range, resulting in synthetic resin finished foam, the surface is not smooth, dielectric Performance degradation, low yield. Used in high temperature lead to silica fog, whitening products, dielectric decline. EC ≈ 60 ~ 100μS / cm, easy to absorb moisture.

3. Magnesium hydroxide flame retardant

Advantages: the application of magnesium hydroxide flame retardant (430 ℃ decomposition) non-toxic

Disadvantages: not acid, acetic acid can dissolve magnesium hydroxide, only suitable for low-end products. Easy to absorb moisture, poor dispersion, poor dielectric.

4. High heat boehmite flame retardant (Boehmite, ALOOH)

Advantages: 1% dehydration temperature above 350 ℃, 500 ℃ dehydration peak, EC <50μS / cm, strong dielectric, to solve the aluminum hydroxide due to low dehydration temperature and lead to product defects and dielectric problems, Strong acid and alkali.

Disadvantages: Flammability slightly lower than aluminum hydroxide, to achieve the same flame retardant performance to be more. But its greatest feature is the high heat resistance, both thermal conductivity, Naisuan Jian, made of high heat resistance of functional materials can increase the value-added products.
