CRS Sales & Marketing Presenter: Gena Miller Thank you AIA, Sign In Sheet (1 Hour CEU-HSW) Division of CRS, Inc. (Commercial Roofing Specialties) 5 Locations (4 state of GA, 1 state of TN) CRS, Inc. Has All Types of Roofing Products Marketing Specializing in Carlisle Single Ply Membrane
Historical Overview TPO Thermoplastic Polyolefin In the early 80 s the heat welded roofing market was mostly PVC and Hypalon TPOreplaced PVC in the in Auto Industry in the 80 s Roofing installations as early as 1989 Up to 1993 manufacturers modified the membrane to get the best formulation Brominated membranes where replaced with non- halogenated membranes for flame retardants

TPO Composition Blend of Polypropylene & Ethylene Propylene Rubber Ethylene-Propylene rubber has exceptional low temperature flexibility Thermoplastic - Heat Weldable No plasticizers No Chlorine Fully cured
TPO Composition TPO polymer ( resin ) is mixed with other ingredients UV light stabilizers & antioxidants to resist solar UV radiation and oxidation Flame retardants to resist flame propagation in order to exceed fire code requirements Pigments add color ( gray, tan, etc. ) Polyester fabric increases rupture properties ( break, tear, puncture, etc. )
TPO TPO ASTM & PVC ASTM RD6878-08e1 - Standard Specification for Thermoplastic Polyolefin Based Sheet Roofing Originally approved in 2003, last previous edition approved in 2006 as D 6878 06a PVC D 4434/D 4434M 09 - Standard Specification for Poly(Vinyl Chloride) Sheet Roofing Originally approved in 1985, last previous edition approved in 2006 as D 4434 06
TPO Bridges Thermoplastic and Rubber Technology High strength High elongation High water resistance High impact strength Low temperature flexibility Excellent weather resistance
Recycling TPO TPO is 100% recyclable Sheet can be ground into flakes and used in bottom ply Average recycle content of bottom ply is 15%

TPO ADVANTAGES TPO not adversely affected by most common chemicals found in roof environment TPO can be used on restaurants, airports and other manufacturing facilities TPO is not degraded by jet exhaust soot or deicing fluids TPO has no plasticizer plasticizers can be extracted by fluids TPO, like all Heat Welded membranes, is degraded by long term direct contact with liquid jet fuel & aviation gas
Weather Testing Exposes samples to UV, infrared radiation, ozone, heat and water spray TPO passed 17,640 kj/m² 80 C / 8000 Hours PVC passed 12,600 kj/m² 63 C / 5000 Hours Xenon-Arc Weatherometer
