Seaman Corporation’s 45 mil FiberTite-SM-FB “fleece back” features an 18 x 19 / 840 x 1,000 denier weft reinforced <br />polyester knit fabric, coated with a proprietary compound, utilizing DuPont’s™ Elvaloy® Ketone Ethylene Ester (KEE) <br />as the principle polymer in the hybrid vinyl alloy coating. <br />Product Data <br />MEMBRANE <br />45 mil FiberTite-SM-FB <br />DESCRIPTION PHYSICAL PROPERTIES <br />45 mil FiberTite-SM-FB “fleece back” is a 40-oz sq. yd/nominal <br />45-mil (1.1 mm) thick membrane. 45 mil FiberTite-SM-FB not only <br />meets or exceeds the minimum physical property requirements <br />enumerated in ASTM D6754-15 Standard Specification for <br />Ketone Ethylene Ester (KEE) Based Sheet Roofing, but exceeds <br />the physical properties and performance characteristics of 60-mil <br />competitive products. <br />The 45 mil FiberTite-SM-FB membrane incorporates a 4-oz per <br />sq. yd non-woven polyester felt, heat bonded to the back side of <br />the membrane with a 3-in selvedge edge for field welding. 45 mil <br />FiberTite-SM-FB fleece back is manufactured in conventional 72- <br />in by 80-ft roll goods. <br />Seaman Corporation is vertically integrated, which allows complete <br />control over the manufacturing process from the selection of the <br />yarns, to the engineering, knitting and weaving of the base fabrics <br />to the final coating process. Today, FiberTite Roofing Membranes <br />are the result of Seaman Corporation’s 60 years of applied fabric <br />engineering and coating technology. <br />All FiberTite Roofing Membranes are constructed using high <br />tenacity/heavy weight yarns to create a base fabric reinforcement <br />to impart superior puncture, tensile and tear resistance properties. <br />The base polyester fabrics are primed with a unique and <br />proprietary adhesive coat that lays the foundation to physically <br />bond the KEE coatings to the “fiber” to maximize seam strength <br />and overall membrane performance. <br />45 mil FiberTite-SM-FB is coated on the face with Seaman <br />Corporation’s original “KEE” formulation to provide superior <br />hot air welding characteristics, extreme UV resistance, broad <br />chemical resistance and long-term flexibility and reparability for <br />the installed roofing membrane system. The back side of the <br />membrane is coated with a slightly modified (SM) economical <br />version of Seaman Corporation’s original KEE compound to control <br />membrane costs while offering additional thickness and weather <br />ability. Additionally, 45 mil FiberTite-SM-FB exhibits excellent tear, <br />puncture, fungus, algae and flame resistance that make FiberTite <br />Roofing Systems some of the most sustainable roofing systems <br />available. <br />ASTM D6754-15 Minimum <br />Requirements <br />45 mil-FB Typical <br />Thickness, mm (in.) <br />ASTM D 751 <br />0.81 (0.032)1.14 (0.045 nom.) <br />Thickness over Fiber, mm (in) <br />Optical method (inches) <br />0.18 (0.007).37 (0.0145) <br />Breaking Strength, N (lbf) <br />ASTM D 751 proc.
