ELASTOPHENE® PS 2.2 is an SBS-modified bitumen base ply for use in approved multi-ply membrane and flashing assemblies. ELASTOPHENE PS 2.2 is composed of a proprietary formulation of elastomeric styrene-butadiene-styrene (SBS) polymer modified bitumen and is reinforced with high quality random glass fiber mat. The topside is surfaced with polyolefin burn-off film and the underside is surfaced with fine mineral aggregate to facilitate cold adhesive and hot asphalt applications.
Prior to installation, unroll ELASTOPHENE PS 2.2 onto the roof surface and allow to relax. Place ELASTOPHENE PS 2.2 in desired position and back roll the product. Apply approved cold adhesive or hot asphalt following manufacturer specifications. ELASTOPHENE PS 2.2 is then rolled into the cold adhesive or hot asphalt and subsequently rolled with a weighted roller. Subsequent approved inter-ply or cap ply membranes are applied to ELASTOPHENE PS 2.2 via heat welding. Refer to the SOPREMA SBS Roofing Manual for additional application guidelines.
