When it comes to plastic welding, knowledge is key to having your work last for a very long time. Wondering what the differences are between TPO and PVC for welding projects? Want to know which material is better for your roofing needs? Keep reading to find out everything you need to know about TPO and PVC roofing. What Is TPO Roofing? TPO stands for thermoplastic polyolefin. This single-ply membrane can be made with either ethylene or polyethylene thermoplastic that’s connected to ethylene-propylene rubber. TPO is used to make welds in residential and commercial roofing projects on roofs that are flat or have a low slope. TPO is a favorable welding material for roofing jobs because it’s durable, energy-efficient, and designed with longevity in mind. TPO has some flexibility but is less flexible than PVC. As a result, TPO can be difficult to welding in tight, curved spaces. Its thermoplastic and rubber components make TPO highly resistant to harsh chemicals, strong winds, oil spills, and punctures. It also holds up well in extreme temperatures—without buckling—and withstands weathering. TPO is a cost-effective roofing solution that’s easy to weld. What Is PVC Roofing? PVC stands for polyvinyl chloride. Like TPO, PVC is a single-ply membrane […] read more
