Polyurethane Sandwich Insulation Panels
The Polyurethane Sandwich Insulation Panels utilizes advanced foaming technology, giving the core material an ultra-low heat transfer coefficient and superior insulation properties compared to traditional materials. Its sealed cell structure effectively blocks heat exchange, significantly reducing energy waste and helping to lower operational costs while supporting energy conservation goals.
Product advantages
Outstanding Thermal Insulation Performance
The Polyurethane Sandwich Insulation Panels utilizes advanced foaming technology, giving the core material an ultra-low heat transfer coefficient and superior insulation properties compared to traditional materials. Its sealed cell structure effectively blocks heat exchange, significantly reducing energy waste and helping to lower operational costs while supporting energy conservation goals.
Superior Fire Safety Compliance
The product has passed rigorous fire resistance testing and is certified to meet flame-retardant standards. When exposed to high temperatures, the core material emits minimal smoke and no toxic fumes, while the external metal layer helps prevent fire spread. This makes it especially suited for fire-sensitive environments like hospitals and storage facilities.
Robust and Durable Construction
Featuring a high-strength metal composite design, the panel offers exceptional resistance to weathering, extreme temperatures, moisture, and chemical exposure. It maintains structural integrity over time without cracking or warping, making it a reliable solution for demanding applications such as cold storage and chemical plants.
Lightweight Yet High-Strength Design
These panels achieve a significant reduction in weight without compromising structural strength, thereby decreasing the load on buildings. Their modular design and ease of cutting allow for quick installation, shortening project timelines and reducing labor requirements.
Eco-Friendly and Non-Toxic Materials
Manufactured using safe, non-toxic raw materials and low-carbon processes, the panels release no harmful substances during use. The smooth surface is easy to sanitize and meets stringent hygiene standards for industries like food processing and pharmaceuticals, supporting green building initiatives.
Tailored Customization Options
A variety of Panels customization choices are available-including thickness, dimensions, and coating types-to fit diverse project needs such as cold rooms, cleanrooms, and commercial buildings. End-to-end technical support is provided from design through installation
List of Reasons for Secondary Foaming of Core Materials
Due to various reasons, Polyurethane Sandwich Insulation Panels may be affected by various factors, which may result in secondary foaming of the core material. This is not due to product quality, but rather due to improper use. Therefore, as long as we know the causes and how to prevent them, we can avoid this situation from happening.
|
trigger condition |
risk impact |
preventive measures |
|
High temperature and high humidity storage environment |
When the core material is not completely cured, the residual foaming agent expands due to heat, causing the board to bulge and the strength to decrease. |
Suggested storage temperature: ≤ 50 ℃, humidity: ≤ 70%; Strengthen ventilation and avoid direct sunlight. |
|
Improper installation joint treatment |
After the seal fails, moisture infiltrates and reacts with residual foaming agent, damaging the integrity of the insulation layer. |
Use specialized sealant (such as silicone adhesive), regularly check the joint condition, and repair any damaged areas in a timely manner. |
|
Physical impact during transportation |
External forces cause the core material structure to become loose, resulting in micropores and a decrease in insulation performance. |
Reinforce the packaging (such as wooden case+foam liner) and fix the plate to avoid shaking; Limit the weight of a single shipment. |
|
Long term storage without use |
Polyurethane naturally ages, causing molecular chain breakage, which may lead to slow foaming. |
Prioritize the use of recent production batches; Cover with dust-proof film during long-term storage to avoid high temperature and high humidity environments. |

Transportation mode and delivery time
Route selection
Based on the customer's location, we prioritize matching major routes such as China Europe (25-35 days), China North America (30-40 days), Southeast Asia (15-20 days), etc., using LCL or FCL flexible transportation.
Port coverage: Supports Qingdao Port, China's main export port, as well as international hub ports such as Rotterdam, Long Beach, and Singapore for transshipment.
Packaging and Protection
Moisture proof treatment: The outer layer of the Polyurethane Sandwich Insulation Panels is wrapped with waterproof polyethylene film, and the interior is filled with moisture-proof pearl cotton to prevent the PU from absorbing water and deteriorating due to the humid environment of sea transportation.
Seismic reinforcement: EPE buffer strips are added to the edge of the metal panel, and steel strips are used to reinforce the box after packing to prevent deformation of the board due to bumps during transportation.
