Product Details
Clean room sandwich panel also known as purification panels, are enclosure structural materials specifically designed for special environments with strict requirements on air cleanliness, temperature, humidity, and pressure. They are manufactured through a continuous automated production line, combining high-quality color-coated steel or stainless steel sheets with a high-performance core material.
As the “skin” of a cleanroom, clean room sandwich panel not only provides physical support but also serves as a crucial barrier against dust particles, microorganisms, and chemical contaminants. Widely used in high-end manufacturing fields such as semiconductors, biomedicine, food and beverage, and precision instruments, it is the first line of defense for ensuring process yield and product quality.
Clean Room Sandwich Panel Structure
Overall Structure: Utilizing a “sandwich” composite structure, it consists of two layers of metal panels and a high-performance core material in between, bonded instantaneously under high temperature and pressure using high-strength polyurethane (PU) or epoxy adhesive.
Connection Method: Primarily employing concealed tongue and groove joints. Pre-installed EPDM or silicone sealing strips at the joints, combined with aluminum profiles at the inside and outside corners and rounded corners (R-corners), ensure seamless connection, eliminate dust accumulation dead spots, and guarantee airtightness.
Surface Treatment: The panel surface can be treated with antistatic coating, antibacterial coating, or anti-corrosion coating to meet the specific requirements of different cleanliness levels.
Material Classification
The core difference between cleanroom sandwich panels lies in the combination of the panel and core materials; different combinations determine the applicable environment and cleanliness level.
Classification Dimension | Material Type | Characteristics & Applicability |
|---|---|---|
By Facing Material | Pre-coated Steel (PCM/PPGI) | Most cost-effective, wide color range, good corrosion resistance. Suitable for electronics, food, and general pharmaceutical plants. |
Stainless Steel (304/316) | Excellent acid/alkali resistance, corrosion resistance, and oxidation resistance; easy to clean. Suitable for biopharma, operating rooms, and high-risk food processing zones. | |
Aluminum Plate/Aluminum Alloy | Lightweight, corrosion-resistant, non-sparking. Suitable for explosive atmospheres, aerospace, and high-humidity environments. | |
By Core Material | MgO Board (Magnesium Oxide) | Inorganic material, Class A1 fire rating, high strength. Often laminated with metal facings for high-fire-demand clean areas. |
Rock Wool (RW) | Class A Fire Rated, excellent sound insulation, but requires moisture protection. Suitable for fire walls, fire ceilings, and areas requiring thermal insulation. | |
MgO-Rock Wool Composite | Dual Fire Protection. Solves the issue of pure rock wool absorbing moisture and sagging. Higher strength, preferred for high-grade cleanrooms. | |
Polyurethane (PU/PUR) | Best thermal insulation performance, high strength. Commonly used in cold storage or cleanrooms with strict temperature/humidity control. | |
Polyisocyanurate (PIR) | Better fire performance than PU, good insulation. A high-performance option between PU and Rock Wool. | |
Magnesium Sulfate / Hollow MgO | Class A1 Fire Rated, lightweight, hollow structure facilitates hidden cable routing. Suitable for high-grade electronics factories and hospital operating rooms. | |
Paper Honeycomb / Aluminum Honeycomb | Extremely lightweight, high flatness, fire rating up to B1 or A1 (Aluminum). Suitable for cleanroom ceilings with lower air convection demands. |

Features of Clean room Sandwich Panel
Ultra-Clean Surface: The clean room sandwich panel features a flat, smooth, and seamless splicing design, combined with rounded corners (R-corners), completely eliminating bacterial growth sites and dust accumulation dead spots. It can withstand repeated wiping with strong disinfectants such as alcohol and hydrogen peroxide.
Superior Airtightness: The double guarantee of tongue and groove interlocking and sealing strips ensures a stable positive pressure gradient in the room, effectively preventing the infiltration of external contaminated air and maintaining a unidirectional or turbulent internal flow. Modularity and Flexibility: High degree of prefabrication in the factory, dry assembly on-site, rapid construction like building blocks. Walls can be easily opened for installation of observation windows, pass-through windows, and various instruments, and facilitates later dismantling and expansion.
Integrated Functionality: Hollow-structure panels can house internal piping (electrical wires, gas pipes, process pipes), achieving concealed piping within the walls and maintaining a clean interior appearance. Special functions such as anti-static, antibacterial, and radiation protection can also be integrated.
Safety & Compliance: Utilizing Class A non-combustible materials, meeting FM, UL, and international fire safety standards. The material itself has low outgassing, preventing the release of volatile organic compounds (VOCs) that could pollute the process environment.
