Superior Insulation Performance: Polyurethane Board for Lasting Thermal Efficiency
Xiaolong — Professional Polyurethane Board Producer
Xiaolong makes polyurethane boards designed for one purpose: to keep heat in or out. Our polyurethane board features a closed-cell structure. It has low thermal conductivity and offers stable performance over time. It’s designed to solve this problem perfectly. Xiaolong has backed insulation projects in many industries. This is thanks to steady production and factory-level quality control.

Maintain Solid Working Capabilities
Closed-Cell Waterproof Structure
Closed-cell content of ≥90% blocks moisture from entering the board core.
Helps resist water absorption in humid or wet installation environments.
Lightweight for Load Reduction
Low core density (35–60 kg/m³) reduces the load on roofs, walls, and structural frames.
Easier to handle and install without heavy lifting equipment in most projects.
Strong Adhesion to Substrates
A compressive strength of at least 120 kPa ensures a strong bond with metal, concrete, and panel surfaces.
Suitable for sandwich panel construction and bonded insulation systems.
Stable Performance at Low Temperatures
Rated for an operating temperature range of -50°C to +110°C.
Thermal conductivity ranges from 0.022 to 0.026 W/(m·K). This ensures steady insulation performance.

Serve Multiple Thermal Preservation Projects
Insulation for Cold Storage and Cold Chain Warehouses
Lines cold room walls and ceilings to slow temperature drift.
Helps cold chain operators maintain steady internal temperatures during storage and transfer.
Roof Insulation for Prefabricated Buildings
Used as the insulation core in prefab roof and wall sandwich panels.
Reduces heat transfer through the roof structure in both hot and cold climates.
Tank Insulation for Low-Temperature Storage Tanks
Wraps or lines tanks holding chilled or cryogenic liquids.
Limits condensation and heat ingress on tank surfaces.
Insulation Lining for Containers and Campers
Fitted inside refrigerated containers and mobile units to maintain internal temperature.
Supports a lighter overall unit weight than bulkier insulation materials.
Explore Useful Guidance When Picking Insulation Solutions
1.Do you support grooving, chamfering, or custom-shaped cutting?
You can often do this with our polyurethane board. However, it depends on the thickness, density, and shape you want. Some designs may need adjustment to stay practical for production. Please send us your drawing or specification. This way, we can review it and tell you what's realistic for your order.
2.What is your stock/inventory situation like?
Availability can change based on thickness, density, and size. Some specifications might be in stock, while others may not be available at that time. It's best to check with our sales team directly. Share your specifications and quantity, and we’ll provide you with a current answer.
3.Can you provide product certificates of conformity?
We can often provide certificates or test reports for our polyurethane board. The documents we can provide depend on the product batch, specs, and destination market. Let us know which certification you need. We can check if we can arrange it for your order.
4.Can you provide similar project case studies and client contact references?
We’ve worked on several insulation projects. We might share examples, but it depends on what’s available and what our clients are okay with sharing. We can’t always provide direct contact details. It depends on client privacy. Let us know your project type, and we’ll see what we’re able to put together.
