APP Waterproofing Membrane Application & Characteristics APP uses polyester reinforcement or fiberglass reinforcement as the original source, and APP, APAO, as the modifier, and covers the insulation materials as polyethylene, sands, or gravels. A.P.P. (Atactic Polypropylene Plastomeric) type modified membrane, consisting of a specially formulated bituminous compound of distilled asphalt modified with selected high-grade visco-elastic polymers and reinforced with a high-quality non-woven polyester carrier. An ​APP Waterproofing Membrane​ is coated with either a sanded or talc top surface finish, while the bottom surface is embossed and protected by a heat-sensitive polythene film. This type of finish for the lower surface has been chosen for two specific purposes. General-purpose APP waterproofing membrane designed and manufactured for the specific needs of the roofing contractors. The plastomeric modified bitumen polymer (BPP) which is used gives excellent flexibility and workability on any roof. The carrier is a non-woven reinforced polyester giving excellent performance in terms of mechanical resistance. The high dimensional stability is obtained by insertion of a glass fiber reinforcement inside the polyester itself.
