FLEX SELF-ADHERING REINFORCED TPO MEMBRANE

GENERAL:

Flex Self Adhering TPO Membrane (SAM) is a heat-weldable, single-ply thermoplastic polyolefin (TPO)

sheet designed for fully adhered new roof construction and re-roofing applications. Flex (SAM) is

nominal 45 mil or 60 mil reinforced TPO membrane laminated to an elastomeric pressure-sensitive

adhesive. Flex (SAM) is based on advanced polymerization technology that combines the durability and

weatherability of ethylene-propylene (EP) rubber with the heat weldability of polypropylene. The

membrane is specifically formulated for long-term weather resistance without the use of either polymeric

or liquid plasticizers.

The pressure-sensitive adhesive is a 100% solid, hot melt adhesive that eliminates VOC and odor

concerns typically associated with fully adhered systems. The adhesive is factory applied to provide

uniform thickness yielding consistent field performance. An uncoated edge is maintained to allow for

heat welded field seams. The release liner is silicon coated on both sides to provide consistent, easy

release from the adhesive even if either side accidentally touches the adhesive again after removal.

Flex (SAM) is available in white (highly reflective) 45 mil and 60 mil nominal thicknesses. Available

widths are 5 and 10 ft in 50 and 100 ft rolls. The membrane is environmentally friendly and safe to install

with its VOC free pressure sensitive adhesive and heat welded seams.

Flex (SAM) white TPO membranes are LEEDTM (Leadership in Energy and Environmental Design)

compliant. The U.S. Green Building Council (USGBC) designed by the LEED Green Building Rating

System. White Flex (SAM) is an ENERGY STAR® and California Title 24 rated roof product.

FEATURES:

• High tack, pressure sensitive adhesive

• Wide window of weldability

• Outstanding puncture resistance

• Chlorine-free with no halogenated flame retardants

• Plasticizer-free, does not contain liquid or polymeric plasticizers

• Excellent low temperature impact resistance

• Excellent chemical resistance to acids, bases and restaurant exhaust emissions

• Exceptional resistance to solar UV, ozone and oxidation

• Low water vapor permeance and water absorption

• Hot melt extrusion processed for complete scrim encapsulation

• Warp knitted fabric (not woven) for smooth surface and greater thickness-over-scrim

• Polyester reinforcing fabric which is resistant to degradation by bacteria, mildew and fungi

• Consistent color
