Product Introduction
High Strength MGO Board for SIP Panel
This board is a high-strength inorganic composite material, specifically made for producing SIP panels. It uses high-purity magnesium oxide, food-grade magnesium sulfate (no chlorine), and is reinforced with multiple layers of alkali-resistant fiberglass mesh plus high-modulus plant fiber as its core formula. We make it with high-pressure molding and precise curing, which creates a dense crystal structure-giving it great flexural strength, impact resistance, and strong bonding with SIP cores.
Design Purpose for SIP PanelsSIP panels need their facings to do a few key things: first, bear structural loads like wind, seismic forces, and their own weight; second, bond stably with the insulation core; third, resist moisture, fire, and environmental damage; fourth, stay dimensionally stable so they don't separate from the core. This High Strength MGO Board is designed to meet all these needs-it acts as the "structural skeleton" of SIP panels, while making them safer and longer-lasting.
Advantage of High Strength MGO Board for SIP Panel
1 High Strength: Structural-Grade Load Bearing
It's extremely strong, way stronger than regular MGO boards and OSB.It can handle impacts during transportation and installation without cracking.It bonds tightly with SIP cores, so the facing and core won't separate-even when temperatures change a lot or there's structural stress.It's suitable for SIP panels used in walls, roofs, and floors of low-to-mid-rise buildings, supporting wind and vertical loads.
2 Class A1 Fire Resistance:
Enhances SIP SafetyIt's a top non-combustible grade, getting rid of the fire risk from traditional flammable SIP facings that give off toxic smoke.When paired with SIP cores, it meets fire safety standards for homes and commercial buildings.It stays structurally strong at high temperatures, stopping the core from melting and fires from spreading.
3 Chlorine-Free & Moisture Resistance:
Protects SIP LongevityIt has no chlorine, so it won't corrode steel parts or SIP frames-preventing rust damage.It doesn't absorb much water, won't swell, deform, or have efflorescence. It also stops mold growth, making it good for humid areas and outdoor use.It expands and contracts similarly to SIP cores, so it won't separate due to temperature changes.
4 Bonding Compatibility:
Optimized for SIP ProductionIts surface (matte or textured, customizable) bonds well with different adhesives, ensuring even bonding when making SIP panels.It has precise dimensions and edge designs, so SIP panels splice tightly-reducing air leakage and improving insulation.
5 Environmental Safety & Durability
It's eco-friendly-no asbestos, no formaldehyde, and recyclable, meeting green building standards.It's made of inorganic materials, so it resists termites, rot, and UV damage (with proper outdoor treatment). It makes SIP panels last for a very long time.
Jinan Fandeng New Material Co.,Ltd.
We are a company dedicated to magnesia cement products. Our main products are Magnesium Oxide Boards (MGO Board) for construction and laminated MgO boards for furniture and renovation. Our mission is to provide the world's construction markets with environmentally friendly, high-performance and sustainable green materials.
We work with China Magnesium Materials Association (CMMA) and Magnesium Oxide Association (MOCA) in North America to raise awareness and promote the use of magnesium oxide cement products. We focus on the quality control and consistency of the MGO products. We have been actively involved in developing American Society for Testing and Materials (ASTM) standards related with MGO products.

SIP Panel Integration & Installation Guidelines
1. Compatibility with SIP Cores
Suitable for all common SIP insulation cores: EPS (expanded polystyrene), XPS (extruded polystyrene), PU foam (polyurethane), and mineral wool.
Recommended adhesive types: Two-component polyurethane adhesive, acrylic structural adhesive (meets ASTM C273 standards for bonding strength).
2. Installation Process for SIP Panels
Lamination: The MGO board is bonded to both sides of the insulation core via automatic SIP lamination equipment (pressure: 0.3–0.5MPa, curing time: 24h at 25℃).
Fixing: SIP panels are installed with stainless steel screws or bolts (spacing: 200–300mm) , at the edges and studs-no pre-drilling required for the MGO facing (high strength avoids cracking).
Joint Treatment: SIP panel joints are sealed with weather-resistant sealant; the MGO facing can be directly painted, tiled, or covered with exterior cladding (e.g., vinyl siding, fiber cement boards) without additional backing.
3. Key Notes
Store the MGO board in a dry, well-ventilated area to avoid moisture absorption before lamination.
Ensure the SIP core surface is clean and dry (no dust, oil) for optimal bonding.
Application Scenarios
This High Strength MGO Board is specifically designed for SIP panels in:
Residential Buildings: Prefabricated houses, modular homes, villas (walls, roofs, floors)-enhancing fire safety and energy efficiency.
Commercial Buildings: Offices, hotels, retail stores (interior/exterior walls, partitions)-meeting strict fire codes and reducing construction time.
Industrial Buildings: Warehouses, workshops, clean rooms (lightweight, fast-installation SIP walls)-resisting moisture and corrosion.
Special Projects: Coastal buildings (salt-spray resistant), cold regions (compatible with underfloor heating), and disaster-relief prefabricated houses (durable and fire-safe).
