With the wide use of waterproof coiled materials, there are more and more types of waterproof coiled materials. It is believed that everyone is familiar with modified asphalt waterproof coiled materials. So, do you know another waterproof roll that Xiao Bian said today? He is a TPO waterproof roll. Today, Xiaobian will make a comparison between the two materials from the following three aspects. I believe you will understand after reading them.

Today, Xiaobian will make a comparison between the two materials from the following three aspects. I believe you will understand after reading them.
1. Material:
Modified asphalt waterproof roll: main component: asphalt, other components: polymer modifier: SBS, APP fiber: polyester, glass fiber PE or PET protective film, sand or stone chips, aluminum foil protective layer.
TPO waterproof coiled material: main components: polymer film, thermoplastic polyolefin waterproof coiled material, a new type of waterproof coiled material based on thermoplastic polyolefin (TPO) synthetic resin, combined with ethylene propylene rubber and polypropylene, added with antioxidant, antioxidant and softener. Polyester fiber mesh can be used as internal reinforcement to make reinforced waterproof roll.
2. Place of use:
Modified asphalt waterproof coiled material: widely used in roof, basement, toilet and other waterproof projects of industrial and civil buildings, as well as roof garden, road, bridge, tunnel, parking lot, swimming pool and other projects. For projects with large deformation, it is recommended to use polyester tires with excellent elongation performance, and for other buildings, use glass fiber tires that are relatively economical.
TPO waterproof coiled material: It is very suitable for use as the waterproof layer of light energy-saving roofs, large factories and environmental protection buildings. It can also be used in drinking water reservoirs, toilets, basements, tunnels, grain depots, subways, reservoirs and other waterproof and moisture-proof projects.
3、 Waterproof principle:
Modified asphalt waterproof coiled material: asphalt has good hydrophobicity and can isolate water vapor. After modification with SBS, the stability of asphalt is greatly improved and it is suitable for various occasions.
TPO waterproof coiled material: macromolecule membrane is used as the isolation layer to isolate water vapor and achieve waterproof effect.
