TPO (Thermoplastic Polyolefin) Waterproof Membrane

• Strong Weather Resistance: Excellent UV resistance, high/low temperature tolerance (-50℃ to 120℃), and aging resistance, ensuring long service life.

• High Durability: High strength and elongation, effectively resisting substrate cracking and deformation.

• Environmentally Friendly & Safe: Chlorine-free, no plasticizers, hot-weld installation without harmful gas emission.

• Easy Installation: Smooth surface, lightweight, can use fully automatic hot-air welding, ensuring high seam reliability.

Widely used for industrial and civil building roofing waterproofing, especially suitable for lightweight steel structure roofs, green roofs, and projects with high environmental and weathering requirements.

• Substrate Preparation: Surface must be flat, firm, clean, and dry.

• Membrane Installation: Mechanical fixing, full-bonding, or loose-laid with weighted seam methods can be used.

• Seam Welding: Use automatic hot-air welding machine to weld overlaps, ensuring continuous, uniform, and strong seams.

• Detail Treatment: Reinforce areas such as inside/outside corners and gutters.

Store in a ventilated place, protected from sunlight and rain. Storage temperature should not exceed 45℃.

Max stacking height: 5 layers when flat; single layer when upright. Avoid contact with acids, alkalis, oils, or organic solvents.

Shelf life: 1 year under normal storage conditions. Transport carefully to prevent tilting or horizontal compression; cover if necessary.

Substrate temperature should not be below 5℃; avoid installation in rain, snow, or wind above level 5.

Clean overlap areas thoroughly before welding and adjust equipment according to site temperature. Handle rolls gently to avoid edge damage.
