The invented product is a fleecebacked laminate that is suitable as a
single-ply fleecebacked roofing membrane. The laminate consists of the
following: 1) a thermoplastic reinforced planar sheet, 2) a needle
punched fleece formed on both sides of the thermoplastic reinforced
planar sheet, and 3) a thermoplastic polymeric layer extruded onto one
side of the fleece. The fleece is formed by needle punching fibers
through the reinforced planar sheet. The reinforced planar sheet serves
as a common supporting base the resulting two-side fleece. The
thermoplastic polymeric layer is embedded with one side of the fleece
fibers. The thermoplastic polymeric layer serves as the top layer of the
roofing membrane, and the second side of exposed fleece serves as a felt.
The thermoplastic polymeric layer is preferably comprised of an extruded
PVC substrate, compounded to have excellent weather resistance,
printability and to be nonflammable. The fleece fibers are preferably
composed of polyester. The thermoplastic reinforced planar sheet is
preferably a scrim that is extrusion coated with a thermoplastic
substrate that is compounded to have excellent weather resistance, and to
be nonflammable.
