Cetco Coreflex Xp — CETCFXP72417

SKU: 862272

COREFLEX XP is a 1.5 mm (60-mil) nominal thermoplastic membrane reinforced with a 90 gram/sqm polyester reinforcing scrim integrally bonded to an XP Technology Core. COREFLEX XP offers the ultimate in waterproofing barrier protection featuring XP technology, the latest innovation in active waterproofing. This advanced polymer technology provides exceptional performance in a wide range of ground contaminates, including high-salinity conditions. The barrier performance starts with a thermoplastic membrane with welded seams providing a monolithic watertight barrier layer. The thermoplastic membrane is reinforced with a polyester reinforcing scrim and is produced with DuPont’s Elvaloy-KEE® (Keytone Ethylene Ester), a solid phase high molecular weight ethylene interpolymer. Unlike traditional liquid PVC plasticizers, the Elvaloy-KEE® does not experience phase separation and migrate out; thus the membrane properties are maintained for long term performance. Elvaloy-KEE® also provides superior chemical resistance properties. The XP Technology Core layer is integrally bonded to the Elvaloy-KEE® thermoplastic membrane. The XP layer is designed to activate with water to swell and form a positive seal. Thereby, at any unforeseen puncture or installation defect, the XP layer reacts at the breach, self-sealing to stop the water ingress. COREFLEX XP is the only welded thermoplastic membrane composite with this reactive, self-sealing XP technology feature.
