A multi-layered membrane comprising skin layers including an ethylene-based olefinic block copolymer (EBOC); and two or more core layers including a propylene-based elastomer (PBE).

Multi-layered thermoplastic roofing membranes

A thermoplastic roofing membrane comprising a planar-shaped thermoplastic body, said planar body having opposed first and second external planar surfaces, where said first surface includes an ethylene-based olefinic block copolymer and a fatty acid amide, where the amount of fatty acid amide provides the surface with a coefficient of friction (ASTM D 1894) of less than 0.250.

Thermoplastic roofing membranes for fully-adhered roofing systems

A method of preparing a thermoplastic roofing membrane, the method comprising (i) extruding a composition including a thermoplastic polymer and a mineral filler to form an extrudate; (ii) forming the extrudate into a sheet having first and second planar surfaces; (iii) allowing the sheet to at least partially cool; and (iv) mechanically treating the first planar surface of the sheet to thereby expose the mineral filler.

Thermoplastic roofing membranes adapted for adhesion to polar adhesives

A multi-layered thermoplastic roofing membrane comprising a planar body including at least three layers, said at least three layers including (i) a top layer that includes magnesium hydroxide dispersed within a thermoplastic resin, (ii) an upper middle layer disposed below said top layer and including magnesium hydroxide and calcium carbonate dispersed within a thermoplastic resin, and (iii) a lower layer disposed below said upper middle layer and including magnesium hydroxide and calcium carbonate dispersed within a thermoplastic resin.

Polyolefin thermoplastic roofing membranes with improved burn resistivity

A thermoplastic roofing membrane including a planar thermoplastic sheet, optionally having more than one layer, where at least one layer of the membrane includes an ethylene-based olefinic block copolymer, and where the sheet is characterized by a storage modulus of less than 450 MPa at 0&#xb0; C.

A thermoplastic membrane composite comprising (i) a planar thermoplastic body having first and second opposed planar surfaces; (ii) a fabric backing fixedly attached to said first planar surface thereby forming an interface between said thermoplastic body and said fabric backing; and (iii) expandable graphite disposed at or near the interface.

Fire-resistant thermoplastic membrane composite and method of manufacturing the same

A thermoplastic membrane including at least one layer including a thermoplastic polyolefin and a functionalized polyolefin copolymer.

An adhered roofing system comprising a roof substrate, a thermoplastic membrane including at least one layer that includes a functionalized thermoplastic polymer, and an adhesive securing the membrane to the substrate, where the adhesive includes a cured residue of a polymer having a silicon-containing hydrolyzable terminal group.
