Plastic Ventilation Ducts: PP and PVC in Chemical Environments
In environments with chemicals, choosing the right material for ventilation ducts is extra important. We offer several options that can be used to create safe and effective systems. Here, we take a closer look at polypropylene homopolymer (PP-H) and PVC-U, two common materials in these contexts.
PP-H for Harsh Environments
PP-H is a good choice when there's a risk of aggressive fumes. The material has high chemical resistance and withstands attack from many harmful substances. We customize the dimensions to your requirements, so the ducts fit perfectly in your project.
How do you know which material is best? It mainly depends on which chemicals the ventilation duct will be exposed to. If there are strong, aggressive fumes, PP-H is a safe bet.
PVC-U for General Ventilation
PVC-U is often used for general ventilation in chemical environments. It's a more affordable option than PP-H, but still has good chemical resistance. In addition, PVC-U is easy to process, cut, and shape.
PVC-U isn't as resistant as PP-H to the very strongest chemicals. But for less demanding applications, it's an excellent alternative. We offer PVC-U in various shapes and sizes.
Choose Material Based on Exposure
When choosing a material, it's important to consider which chemicals the duct will be exposed to. Are you unsure? Feel free to contact us! We have extensive experience with plastic materials in chemical environments and can help you choose the right one.
Temperature also plays a role. High temperature can affect the material's chemical resistance. Then other materials, such as HDPE or POM-C, may be more suitable.
Connection Methods
Once you've chosen a material, it's time to think about how the ducts will be joined. Welding and flanges are common methods. Welding provides strong and tight joints, while flanges can be easier to use.
The choice of connection method depends on the material and how much stress the duct will be exposed to. For PP-H, welding may be best to get a strong and tight connection.
Fire Safety
Fire safety is an important aspect. Choose a material that meets the requirements and make sure the installation is correct. We can help you with the right material and connection method to create a safe and effective ventilation duct.
A material with low flammability and correct installation is important. For example, you can use a material with a hardness of 65° Shore D.
Plastic ducts can be a good choice for handling chemical fumes. By choosing the right material and connection method, you can create a safe and effective system.
