Product Introduction
Magnesium oxide boards are renowned for their exceptional fire resistance, making them an ideal choice for back panels in high-risk environments. Their key fire-resistant features include:
1. Non-Combustible Material
Made from inorganic minerals such as magnesium oxide, magnesium chloride, and magnesium sulfate, magnesium oxide boards are classified as Class A non-combustible materials (GB 8624-2012). When exposed to flames or extreme heat, they do not ignite, support combustion, or contribute to fire spread, effectively containing flames.
2. High-Temperature Stability
Unlike wood or organic composite boards that weaken or release flammable gases under heat, magnesium oxide boards maintain structural integrity even during prolonged fire exposure. This stability provides critical time for fire suppression and safe evacuation.
3. Low-Toxicity Smoke Emission
In fire scenarios, toxic smoke is a leading cause of harm. Magnesium oxide boards emit minimal smoke and contain no volatile organic compounds (VOCs) like formaldehyde or benzene, drastically reducing health risks to occupants.
4. Enhanced Fire Integrity
When used as back panels, magnesium oxide boards form a robust fire-resistant system with structural components like framing and insulation. Their non-combustibility and durability help preserve the panel's integrity, slowing internal fire damage and boosting overall fire resistance in buildings or furniture.
Ideal Applications:
Kitchens
Laboratories
Shopping malls
High-rise buildings
By incorporating magnesium oxide boards, you significantly improve fire safety while meeting stringent regulatory standards.

Ready to tile without any additional waterproofing required.
Product Features:
Magnesium oxide board is a new type of panel with magnesium oxide, magnesium chloride and other inorganic materials as its core, featuring several prominent characteristics:
- Fire resistance and flame retardancy: It is a Class A non-combustible material. It does not burn when exposed to fire, nor does it release toxic fumes, which can effectively delay the spread of fire.
- Moisture and water resistance: It is not easy to deform or get moldy in humid environments, making it suitable for places with high humidity such as bathrooms and kitchens.
- Strength and stability: It has a hard texture, excellent flexural and compressive performance, and a small coefficient of thermal expansion and contraction, so it is not easy to crack after long-term use.
- Environmental protection and safety: It is mainly composed of inorganic components, free of harmful substances like formaldehyde, and not easy to breed bacteria or get infested by insects.
- Ease of processing: It can be sawn, nailed and glued, with a smooth surface, which can be adapted to various decorative treatments. It is widely used in construction, furniture and other fields.
