Buy good quality Expanded Perlite MgO Fire Door Core Fire resistant, Waterproof, and high Insulating boards for manufacturing Fire Doors. 
 
Expanded Perlite MgO Fire Door Core is a specialized composite material used in the construction of high-performance fire-rated doors. This type of core combines magnesium oxide (MgO) with expanded perlite to enhance fire resistance, thermal insulation, and overall door stability. Expanded perlite is a lightweight, porous volcanic glass that, when combined with MgO, provides an effective solution for fire doors in commercial, residential, and industrial settings.
 
Key Features of Expanded Perlite MgO Fire Door Core:
1. Enhanced Fire Resistance:
• The combination of MgO and expanded perlite provides excellent fire resistance, often achieving fire ratings of up to 60, 90, or 120 minutes, depending on the core thickness and construction.
• MgO is a non-combustible material, and the inclusion of expanded perlite further enhances the thermal barrier properties, preventing the spread of fire and heat through the door.
2. Lightweight Composition:
• Expanded perlite significantly reduces the weight of the fire door core, making it easier to handle and install without compromising fire performance.
• The lightweight nature of expanded perlite MgO cores also reduces the overall door weight, which can lower the load on hinges and door frames, prolonging hardware life.
3. Superior Thermal Insulation:
• Expanded perlite has excellent thermal insulation properties due to its porous structure, which traps air and reduces heat transfer.
• This core effectively slows down the rise in temperature on the non-fire side of the door, helping to protect occupants and property during a fire.
4. Moisture and Mold Resistance:
• The combination of MgO and expanded perlite results in a moisture-resistant core that does not swell, warp, or degrade when exposed to humidity or water.
• This resistance to moisture also prevents mold and mildew growth, contributing to healthier indoor environments.
5. Sound Insulation:
• The porous nature of expanded perlite, combined with MgO, provides good sound insulation, making these cores suitable for doors in noise-sensitive areas such as offices, hotels, and hospitals.
6. Environmental and Health Benefits:
• MgO and expanded perlite are environmentally friendly, made from abundant natural minerals without harmful chemicals.
• The materials do not emit volatile organic compounds (VOCs), contributing to better indoor air quality and meeting green building standards.
 
Applications of Expanded Perlite MgO Fire Door Core:
• Fire-Rated Doors: Used in various fire-rated doors, including those in commercial buildings, residential high-rises, schools, and healthcare facilities, to provide critical fire protection.
• Smoke Control Doors: Suitable for doors designed to limit smoke penetration, enhancing safety in escape routes during fires.
• Acoustic Doors: The sound insulation properties make these cores ideal for fire doors in environments requiring noise reduction along with fire safety.
• Lightweight Applications: Ideal for situations where reducing door weight is beneficial without sacrificing fire protection, such as in retrofitting older buildings or areas with limited structural load capacity.
 
Installation and Fabrication:
• Customization: Expanded perlite MgO cores can be customized to various thicknesses and sizes to meet specific fire rating requirements and door dimensions.
• Surface Compatibility: These cores can be laminated with a variety of surface finishes, including wood veneers, laminates, steel, or fiberglass, allowing them to blend seamlessly with the design aesthetic.
• Hardware Integration: The cores are easy to work with for integrating door hardware such as locks, hinges, and closers, ensuring proper fit and function.
 
Compliance and Standards:
• Ensure the expanded perlite MgO fire door cores meet the relevant fire safety standards and certifications, such as UL, EN, or BS, for their intended use.
• Proper testing and certification are essential to confirm that the doors will perform as required in a fire event.
