Overview
Halogenide resistance is a key indicator of magnesium oxide board (Mag boards) quality, especially in humid environments. Poor resistance can lead to issues like board “sweating,” structural damage, and customer complaints — problems seen in many early MgCl₂ boards.
In this test, we evaluated Suparna Mag boards under high humidity and temperature for 15 days. The results clearly show that our boards maintain excellent performance without moisture or surface defects, confirming their strong halogenide resistance.

Test Description
1. Test item: Halogenide resistance of mag boards
2. Sample description: See photo below
3. Test method:
Cut boards of 200*200 mm on each of the three sample Mag boards.
Put them into a constant temperature and humidity chamber with a relative humidity of 90% or more and a temperature of 30-35 °C.
Take them out after 24 hours to see if there is any water drops or moisture.
4. Test condition: 30~35℃, 90%RH, 15 days
