Polyurethane sandwich panels are widely used in construction sector. PU panels are made by casting polyurethane prepolymer with polyol and isocyanate. Polyurethane panels are suitable for indoor and outdoor environments. The polyurethane is formed on the surface of both sides of the steel plate or the aluminum plate through the continuous and discontinuous production line, and a variety of decorative materials can be attached to the surface of the plate. Continuous pu sandwich panel production is faster than discontinuous production line. PU sandwich panel line can be customized according to needs.
Polyurethane sandwich panels are widely used in construction sector. Polyurethane foam is an excellent insulator and is therefore used in building, wall and roof insulation. It is also used in furniture, decoration etc.
In case of polyurethane sandwich panels the two outer surfaces are made up of glass fiber sheets impregnated with resin which provides strength to the panel and also acts as moisture barrier preventing moisture from entering into the core between glass fiber sheets from either side creating a water tight seal around it.
In another type of sandwich panel one or both sides may be made up of foamed polystyrene plastic instead of glass fiber sheets. The core material between these two layers can vary depending on use but usually it is some kind of foam such as polyester or polyisocyanurate which has higher R value than other types due to low thermal conductivity properties.
Cast polyurethane prepolymer is a light-weight material that is used in the production of PU panels. Polyurethane prepolymer is a resin that has not undergone reaction with any hardener or catalyst. The main components of cast polyurethane prepolymer include:
Polyol – this is an organic compound (a molecule containing carbon, hydrogen and oxygen)
Isocyanate – this is also an organic compound (a molecule containing carbon, hydrogen and nitrogen).
Polyurethane panels are suitable for indoor and outdoor environments. They are strong and durable, waterproof, fireproof, easy to clean and install. These panels are light weight and easy to transport.
These properties make them ideal for use in places where you require a material that will stand up to heavy traffic as well as harsh weather conditions. For example, they can be used on patios or terraces where children play or pets run around without causing damage like a traditional wooden deck would do over time due to wear & tear from footsteps etcetera..
The polyurethane is formed on the surface of both sides of the steel plate or the aluminum plate through the continuous and discontinuous production line, and a variety of decorative materials can be attached to the surface of the plate. The thickness of plates used in pu can also be controlled within a certain range according to different project requirements so that it has good heat insulation performance. In addition, there are various types of surface treatment available for pu panels such as powder coating, electroplating, rubber coating and so on.
Compared to discontinuous production, continuous production is more efficient. Continuous production lines are made up of several PU sandwich panel machines that work together to produce panels for you. This is beneficial because it allows you to produce a high volume of panels quickly and efficiently. A continuous sandwich panel line also has the ability to produce different types of panels, which makes it easier for your company to make multiple products in one location.
Continuous pu sandwich panel production is faster than discontinuous PU sandwich panel production line because the machines are constantly running without stopping or slowing down during operation. As a result, it takes less time for one person working alone on a continuous line than someone working alone on their own individual machine at their own pace would take when making the same product using similar equipment (or even just doing manual work). Because there aren't any long breaks between steps or processes involved with making these panels (like waiting for glue curing), there's no downtime either!
PU Sandwich Production Line can be customized according to needs. It is suitable for indoor and outdoor environments, such as stadiums, schools, hospitals, offices and commercial buildings.
We believe the benefits of using polyurethane panels outweigh their disadvantages, making them a viable option for many construction projects. If you need more information about how these panels are made, please contact us today! We look forward to hearing from you!
