Magnesium hydroxide for Cable Filler

Description

EVA is widely used to produce cable filling compound because of its easy filing and good compatibility with magnesium hydroxide. The magnesium hydroxide for cable filler made of EVA and Mg(OH)₂ is very good to improve the combustion performance of halogen free flame retardant cable.

Flame-retardant mechanism of Magnesium Hydroxide for Cable Filler

1. Decomposition of magnesium hydroxide absorbs heat, which is beneficial to reduce the flame combustion temperature.
2. The decomposition of magnesium hydroxide create water, it’s not only the coolant, also reduce the smoke density.
3. The decomposition of magnesium hydroxide creates MgO, which is featured with big specific surface. So it is easy to absorb smoke and cover the combustible material.
