YN-A680 Thermoplastic Polyolefin (TPO) Waterproof Membrane

1. Advanced polymerization technology is employed to combine the advantages of ethylene propylene rubber and polypropylene, resulting in a material that possesses both the excellent weather resistance of ethylene propylene rubber and the weldability of polypropylene.
2. Special formulation technology is used, eliminating the need for any plasticizers that can make the material brittle.
3. It does not exhibit the brittleness caused by plasticizer migration that is common in thermally welded membranes (such as PVC), maintaining long-term waterproof functionality.
4. It exhibits good high and low-temperature resistance, maintaining flexibility at -50°C like rubber materials and retaining mechanical strength at higher temperatures.
5. It is resistant to chemicals, acids, bases, salts, animal and vegetable oils, lubricating oils, and corrosion from algae, mold, and other microorganisms.
6. It is resistant to thermal aging and has good dimensional stability.
7. Its surface is primarily light-colored, primarily white, and smooth.
8. The lap seams are formed using thermal welding, creating a high-strength, sealed waterproof layer.

1. During storage and transportation, products of different types and specifications should be stacked separately and not mixed. Avoid exposure to sunlight and rain, and ensure proper ventilation.
2. The storage temperature should not exceed 45°C. Stack flatly with a height not exceeding 5 layers, or stand singly. Avoid contact with acids, alkalis, oils, and organic solvents.
3. During transportation, prevent tilting or horizontal compression, and cover with tarpaulins if necessary.
4. Under normal storage and transportation conditions, the shelf life is 1 year from the date of production.

1. It is widely used in green roofs, exposed single-ply roof waterproofing projects, large venues, airports.
2. Underground civil defense shelters, dams, landfills, subways, tunnels, bridges, and grain storage facilities.

TPO Waterproof Membrane Mechanical Fixation System Construction Process:

Base surface cleaning → Laying polyethylene film → Laying insulation board → Pre-laying TPO waterproof membrane → Fixing TPO waterproof membrane with fasteners → Hot air welding of TPO waterproof membrane → Strengthening treatment of joints → Inspection and repair → Organization of acceptance

TPO Waterproof Membrane Loose-lay System Construction Process:

Base surface cleaning → Pre-laying TPO waterproof membrane → Hot air welding of TPO waterproof membrane → Strengthening treatment of joints → Inspection and repair → Organization of acceptance

TPO Waterproof Membrane Fully Adhered System Construction Process:

Base surface cleaning → Positioning and snapping lines → Strengthening treatment of joints → Applying adhesive on large surfaces → Laying and pasting waterproof membrane → Membrane overlapping → Sealing the ends → Organization of acceptance

1. According to the design requirements of the drawings, different projects have different technical specifications and can be customized to meet the design requirements.

2. The execution standard is: GB 27789-2011.
