Plastic ventilation ducts: PP and PVC in chemical environments
In environments containing chemicals, it is particularly important to choose the right material for the ventilation ducts. We offer several options that can be used to create safe and efficient 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 where there is a risk of aggressive vapours. The material has high chemical resistance and withstands attack from many harmful substances. We tailor the dimensions to your requirements, ensuring the ducts fit your project perfectly.
So how do you know which material is best suited? It depends primarily on the chemicals to which the ventilation duct will be exposed. If there are strong, aggressive vapours, PP-H is a safe bet.
PVC-U for general ventilation
PVC-U is often used for general ventilation in chemical environments. It is a more cost-effective alternative to PP-H, but still offers good chemical resistance. Furthermore, PVC-U is easy to work with, cut and shape.
PVC-U is not as resistant as PP-H to the very strongest chemicals. However, for less demanding applications, it is an excellent choice. We offer PVC-U in various shapes and sizes.
Choose the material based on exposure
When choosing a material, it is therefore important to consider which chemicals the duct will be exposed to. Are you unsure? Please feel free to contact us! We have extensive experience of plastic materials in chemical environments and can help you make the right choice.
Temperature is also a factor. High temperatures can affect the material’s chemical resistance. In such cases, other materials, such as PE-HD or POM C, may be more suitable.
Connection methods
Once you have chosen the material, it is time to consider how the ducts will be joined. Welding and flanges are common methods. Welding produces strong and tight joints, whilst flanges may be easier to use.
The choice of connection method depends on the material and the load the duct will be subjected to. For PP-H, welding may be the best option for achieving a strong and tight connection.
Fire safety
Fire safety is an important consideration. Choose a material that meets the requirements and ensure the installation is carried out correctly. We can help you select the right material and connection method to create a safe and efficient ventilation duct.
A material with low flammability and correct installation are essential.
Plastic ducts can be a good choice for handling chemical vapours. By choosing the right material and connection method, you can create a safe and efficient system.
