Composition and Properties of PU Panels
What are PU panels made of?
Polyurethane foam core
The middle part of a PU panel is made of foam. This foam, called polyurethane, is great for keeping heat in or out. It is made by mixing two chemicals, isocyanate and polyol. These chemicals create a strong but light material. Sometimes, makers add things like silane to make the foam work better. Other panels may include materials like phyllite or recycled fibers. These extras make the foam stronger and better at keeping heat in or out.
Outer layers (e.g., metal, plastic)
PU panels have outer layers made of metal or plastic. These layers protect the foam and make the panel stronger. For example, some panels use steel covered with a special coating. Others use recycled plastic materials. These outer layers make the panels light, easy to use, and tough against damage.
Material Component | Description |
|---|---|
Core Material | Foam core that keeps heat in or out. |
Facing Materials | Recycled plastic or coated steel for strength and protection. |
Reinforcements | Added materials like phyllite or fibers for extra strength. |
Key properties of PU panels
Thermal insulation
PU panels are great at keeping buildings warm or cool. The foam inside stops heat from moving in or out. Adding tiny particles like phyllite makes the foam even better at this job.
Lightweight and durable
PU panels are strong but not heavy. This makes them easy to carry and put in place. They last a long time and resist water, bugs, and damage. This makes them a good choice for building projects.
Fire resistance (varies by grade)
Some PU panels can resist fire, depending on their type. High-quality panels meet strict fire safety rules. Some are even coated to make them safer from fire.
Property | Description |
|---|---|
Durometer (Hardness) | Shows how tough the panel is against dents. |
Resilience | Handles shocks and shakes, making it useful in many ways. |
Compression | Can hold heavy weights, making it good for building. |
PU panels mix these features to be useful and efficient for modern buildings.

PU Panels vs. Other Materials
PU panels vs. PIR panels
Differences in chemical makeup
PU panels and PIR panels have different foam cores. PU panels use open-cell polyurethane foam. PIR panels use closed-cell polyisocyanurate foam. This difference changes how they work. PIR panels insulate better with a higher R-value. They also resist fire more due to their closed-cell design. PU panels are less tough outdoors compared to PIR panels.
Feature | PU Panels | PIR Panels |
|---|---|---|
Chemical Composition | Open-cell polyurethane foam | Closed-cell polyisocyanurate foam |
Thermal Insulation | Higher R-value, better insulation | |
Moderate fire resistance | Better fire resistance | |
Durability | Less durable outside | More durable for outdoor use |
Structure | Open-cell structure | Closed-cell structure |
Comparing insulation and fire safety
Both panels insulate well, but PIR panels do it better. PIR panels also handle fire better, making them safer. PU panels can be treated for fire safety. However, they are still less fireproof than PIR panels.
Feature | PU Panels | PIR Panels |
|---|---|---|
Fire Resistance | Treated for fire safety, less fireproof | Handles fire better, safer in heat |
Insulation | Works well | Slightly better due to design |
