Foam Core Pipe
-
Foam core pipe, although it is several decades old, is becoming more popular among building and construction projects. While foam core pipe looks just like traditional solid PVC pipe, the difference is in the core, or the area between the inner and outer layers of the pipe. Instead of being made of solid PVC resin, this layer is made of foam. This foam, which is created through a blowing agent called azobis carbonamide, reduces the cost of manufacturing the pipe.
Manufacturing
-
The manufacturing process begins when the thermoplastic resin of PVC is fed into an extruder. This machine melts the resin and moves it forward into a "Y" shape, essentially dividing the melted thermoplastic into two, diverging streams. There is a separate extruder that will feed the foam into the process, putting it between the two streams of PVC resin. Then, to seal them together, the three separate streams are put through a die and cooled. At the end of the process, you have two layers of solid PVC skin, with a layer of foam between them.

Benefits and Drawbacks
-
As plastics have become more common, PVC pipe has grown in demand. Foam core pipe is the same thickness as most PVC pipe, and it can handle many of the same benefits, but it is significantly cheaper to produce and it uses less virgin PVC resin. As a result, foam core pipe is now available as a cheaper alternative, and it is especially useful for projects, such as electrical wiring. However, foam core pipe cannot stand up to the same strains as solid PVC pipe, such as heavier water pressure and having large weight placed on top of it.
