Product Details


APP modified bitumen membrane is made by saturating the base in bitumen, or thermoplastics (such as APP, APAO, APO), then covering double faces with a thermoplastic elastomer (SBS), and lastly finishing the upward face with fine sands, mineral slates(or grains) or polythene membrane, etc. while the downward face with fine sands or polythene membrane.

Characteristic:

 Good impermeability; Possess good tensile strength, elongation rate, and size stability which could be well suited the substrate distortion and crack; SBS-modified bitumen membrane is especially applied in a cold area with low temperature, while APP-modified bitumen membrane is involved in a hot place with high temperature; Good performance in anti-puncture, anti-broker, anti-resistance, anti-erosion, anti-mildew, anti-weathering; Construction is convenient, the melt method can operate in four seasons, joints are reliable

Applicable scope:

Suitable for civil building roofing, underground, bridge, parking, pool, and tunnel in the line of waterproofing and dampproof, especially for building under high temperatures.

According to the roofing engineering stipulation, APP-modified bitumen membrane could be used in the Grade Ⅰ civil building and industrial buildings with special waterproofing requirements.

Storage and transportation instructions

l When storage and transportation, Different types and sizes of products shall be stacked separately, and should not be mixed. Storage temperature should not be above 50℃, the height is not more than two layers, and in the course of transportation, the membrane must stand.

l The stacking height is not more than two layers. To prevent the tilt or pressure, when necessary cover the felt fabric.

l In normal conditions of storage and transportation, the storage period is a year from the date of production

“SINOMTC” Brand Plastomer (APP) modified bitumen waterproof membrane is a kind of flexible sheet waterproof material that uses atactic polypropylene (APP) or polyolefins(APAO, APO) as dipping and coating material, with the upper surface covered by the isolation materials like polyethylene film, fine sand or mineral slice (or particle), etc.

APP Modified Bitumen Membrane

Advantages of app modified bitumens membrane

—Long fiber polyester base membrane:
·Combination of high-performance long fiber polyester filler and APP-modified bitumen, forms an excellent performance.


·Form a high strong waterproof layer and have strong water resistance capability.
·It has high tensile strength, and high elongation, and is adaptive to shrinkage, deformation, and fracture of the base.


·Good performance of low-temperature resistance, corrosion resistance, mold resistance, and weather resistance.


·Large thickness of the high-strength polyester filler, the resistance to puncture, breaking, tearing, and fatigue.


·Good workability: It can be constructed by the heat fusion method in the four seasons of the whole year and hot-joint is reliable and durable.


—Alkali-free glass fiber filler membrane:
·Combination of economical filler base and high-performance APP modified bitumen; to from high tensile strength, large thickness, strong resistance of wearing, and good dimensional stability.


·Excellent high-temperature resistance, corrosion resistance, mold resistance, and weather resistance.


·Good workability, It can be constructed by the heat fusion method in the four seasons of the whole year and hot-joint is reliable and durable.


—Glass fiber reinforced polyester membrane:
·It is safe and eco-friendly by using mechanical mounting of construction and the product has better dimensional stability and fire-resistance performance.

Application Range

Use in different waterproof constructions of all industrial and civil sections, be most appropriate to the following constructions:


·Waterproof constructions for industrial and civil roof projects, including inaccessible roofs, accessible roofs, thermal insulation roofs, non-thermal insulation roofs, planting roofs, roof parking lots, upside-down roofs, and other kinds of normal and special roof constructions.

·Underground waterproof and damp proof for industrial and civil constructions, as well as indoor swimming pools and fire pools, etc;

·Municipal waterproof constructions like subways, tunnels, concrete road and bridge surfaces, sewage works and refuses landfills, etc;

·Waterproof for canals and water pools and another water conservancy.
Application range for different filler base and surface sheet material:

·Glass fiber filler base sheet material: Be appropriate to a normal roof and underground engineering constructions of stable structural buildings.

·Filament polyester filler sheet material: Be appropriate to Grade Ⅰ and Grade Ⅱ roof and underground waterproof projects.
