Description
Magnesium hydroxide for plastics board/sheet is characterized by non-toxic, high efficient, smoke suppression, environmental flame retardant; and its max processing temperature can be 300℃. It is widely used to produce flame retardant board like PE board/sheet, flame retardant ABS board, flame retardant PVC foamed board, flame retardant PVC floor board, flame retardant EVA foamed board, flame retardant WPC board/profile.

Flame-retardant mechanism of Magnesium Hydroxide for Plastics Board/Sheet
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 as thinner.
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.
