TPO (Thermoplastic Polyolefin) is a premium synthetic material used in heavy-duty tarpaulins, roofing membranes, and industrial covers. It combines the durability of PVC with the eco-friendliness of polyolefins, making it a popular choice for UV-resistant, waterproof, and long-lasting applications.
◆ Applications of TPO Tarpaulin:
✔ Roofing Membranes (industrial, commercial, solar-reflective)
✔ Truck & Cargo Covers (lightweight, tear-resistant)
✔ Agricultural Covers (greenhouses, silage tarps)
✔ Inflatable Structures (boats, temporary shelters)
✔ Industrial Curtains & Barriers (warehouses, cleanrooms)
Material Composition
Base Layer
Polypropylene (PP) or polyethylene (PE) blend
Reinforcement
Polyester scrim or fiberglass mesh (optional)
Coating/Finish
UV-stabilized TPO layer
