Versico's VersiFleece AC (Asphalt Compatible) TPO membranes are manufactured using a hot-melt extrusion process for complete scrim encapsulation. Once the TPO is reinforced and enhanced with AC fleece, the total sheet thicknesses are creating a very tough, durable and versatile sheet that is ideal for re-roofing or new construction projects. VersiFleece AC TPO sheets are chlorine free and plasticizer free with excellent chemical resistance to acids, bases, restaurant oils and greases. VersiWeld TPO with Octaguard XT™ weathering package technology withstands extreme durability testing intended to simulate exposure to severe climates. VersiWeld TPO is based on advanced polymerization technology that combines the flexibility of ethylene-propylene (EP) rubber with the heat weldability of polypropylene.
