Tpo and pvc are smooth chemically resistant and water resistant and neither is easy to coat.
Thermoset vs thermoplastic roof.
Thermoset plastics are often used for sealed products due to their resistance to deformation.
On the other hand polyvinyl chloride pvc and thermoplastic polyolefin tpo two other common roofing systems for commercial buildings fall in the second category.
Introduction thermoset vs thermoplastic thermoset and thermoplastics are two separate forms of polymer powders which are differentiated based on their behavior when reacting to the application of heat the primary difference between the two is that thermoset is a material that strengthens when heated but cannot be remolded or heated after the initial forming while thermoplastics can be.
Typically it is more common to see thermoplastics being used in day to day life.
Today single ply roofing makes up the vast majority of the low slope commercial roofing market in north america.
This is due to a chemical reaction that has taken place during the polymerisation.
Thermoset plastics significantly improve the material s mechanical properties providing enhances chemical resistance heat resistance and structural integrity.
Epdm represents a thermoset membrane which means the material doesn t soften when heated.
Epdm an example of thermoset roofing membranes.
Whether it be a small repair roof maintenance program or a total roof replacement.
Single ply roofing membranes fall into two classes thermoset membranes such as ethylene propylene diene monomer epdm and hypalon and thermoplastic membranes such as thermoplastic polyolefin tpo and polyvinyl chloride pvc.
Our firm specializes in confronting and solving the roofing and waterproofing needs of hotels resorts and general contractors property managers and building owners.
An example of thermoset membranes includes ethylene propylene diene monomer epdm one of the most widely used roofing systems.
Because the material doesn t soften the seams must be glued or otherwise adhered and cannot be welded.
Examples of thermoplastic types are pvc polyvinyl chloride and pe polyethylene.
Thermoset materials are also softened by heating and can be shaped and then cooled to retain a new shape however unlike thermoplastic material it is only possible to do this once.
There are two different types of single ply roofing material.
The key difference between thermoplastic and thermoset is that thermoplastic can be melted into any shape and re used whereas thermosets have a permanent shape and cannot be recycled into new forms of plastic.
