The Different types of Cable-Fire-Redartant

May 09, 2017

1. Antimony flame retardant

Advantages: three oxidation of two antimony can not be used as a flame retardant, and with the appropriate use of halogen compounds, can play a particularly effective flame retardant performance. Disadvantages of antimony flame retardant synergistic mechanism of heavy metals, toxic, and arsenic homologues in crude product containing arsenic and other heavy metals, arsenic trioxide. Can not be used as green filler and green flame retardant.


2.Aluminum hydroxide flame retardant (ATH)

Advantages: low price, good flame retardancy.

Disadvantages: poor heat resistance, 200 degrees to dehydration, 330 C and 350 C is completely dehydrated, and the curing of the resin in the aluminum hydroxide dehydration temperature range, thus leading to the synthesis of resin foam, decrease surface unevenness, dielectric properties, low rate of finished products. Applied to the high temperature caused by silica gel fog, white foam products, such as dielectric decline. EC is 60~100 S/cm, easy to absorb moisture.


3.Magnesium hydroxide flame retardant

Advantages: application of magnesium hydroxide flame retardant (430 DEG C decomposition) non-toxic

Disadvantages: not acid, acetic acid can be dissolved in magnesium hydroxide, only suitable for low-grade products. Easy to absorb moisture, poor dispersion, poor dielectric properties.


4.High heat-resistant boehmite flame retardants (Boehmite, ALOOH)

Advantages: 1% dehydration temperature above 350 degrees, 500 degrees of dehydration peak, EC<50 S/cm, dielectric, solves the low temperature caused by dehydration of aluminum hydroxide product defects and dielectric properties decreased, acid and alkali resistance.


Disadvantages: flame retardant slightly lower than aluminum hydroxide, flame retardant performance to achieve the same need to add. However, its biggest feature is high heat resistance, both thermal conductivity, acid and alkali resistance, made of high heat resistance functional materials can improve the added value of the product.
