What are the performance advantages of TPO waterproofing roll-roofing material?
With the development of national dual carbon goals, green building materials, photovoltaic roofing and other related fields have received widespread attention from practitioners. Photovoltaic building integration is a solar photovoltaic power generation system that is designed, constructed and installed at the same time as the building and forms a perfect combination with the building. TPO waterproofing membrane has excellent waterproofing performance, excellent weather resistance and excellent hot air welding performance, high tensile strength, high elongation, wet roof construction, exposed without the need for Protective layer, easy construction, no pollution and other characteristics, can well meet the ultra-long durability requirements of the exposed scenario, can perfectly match the needs of photovoltaic roofing more than 25 years of service life. In addition white coil has good daylight reflectivity, can effectively reduce indoor temperature, to assist in improving power generation efficiency; at the same time easy to repair, late repair and maintenance costs are low, can be said to be once and for all. So what are the advantages of TPO waterproofing roll-roofing material?
TPO refers to thermoplastic polyolefin, is composed of rubber and polyolefin two components of elastomeric materials. TPO waterproofing roll-roofing material is used TPO resin, according to the need to add modifiers (such as flame retardants, ultraviolet absorbers, light stabilizers, etc.), color masterbatch for blending, made suitable for roof exposure environment waterproofing roll-roofing. In practice, TPO waterproofing membrane with aging resistance, high tensile strength, elongation, wet roof construction, exposed without protective layer, construction is convenient, pollution-free and many other advantages, very suitable for use as a light energy-saving roofing waterproof layer.
1, TPO waterproofing roll-roofing material combines the performance advantages of EPDM and PVC, with the former’s weather resistance, low gentleness and the latter’s weldable characteristics. This material, unlike traditional plastics, shows high elasticity of rubber at room temperature, and can be molded like plastic at high temperature.
2, excellent UV resistance, natural aging resistance; does not contain plasticizers, will not be caused by plasticizer seepage, migration and rapid aging phenomenon, making the coil life longer, waterproof effect can be up to 50 years.
3, excellent puncture resistance; good hot air welding construction, the bonding strength of the welded seam is higher than the coil itself, so that the entire waterproof layer to form a whole.
4, excellent low temperature impact resistance (-40 ℃) and resistance to deformation, with high tear strength, high fracture elongation. Good resistance to root penetration, can be made into a planting roof.
5、Excellent resistance to chemical substances, good resistance to various acids, alkalis, oils, bacteria, fungi and algae caused by degradation; environmental protection and can be recycled.
