Hainer E-TPO waterproof membrances:
TPO Waterproof Membrane is composed of TPO surface layer,under-layer, plus reinforced fiber between them. It is featured with good properties of EP rubber like weather-resistance, ozonization resistance and endurance besides good performances of polypropylene like Weldability, chloride-free, plasticizer-free, high reflectivity of sunshine, recovery, safety, energy-saving, environment-friendly; what's more, it has low water -vapour-transmission rate, high heat-resistance, high ageing-resistance, low-temperature resistance, high intensity, stable dimension and color, high tearing strength, high puncture-resistance, excellent physical performance.
The application of the products
TPO waterproof roll is widely used in the various types of the waterproof roofs', special for the waterproof roof of steel construction and reinforced concrete construction.
