3. Applications

  • Various roofing waterproof projects, such as industrial and civil buildings, public constructions;

  • Full adhered system for concrete substrate or mechanically attached systems.

 

4. Advantages

  • Weather resistance and durability;

  • Excellent weld ability;

  • No any crisp agents to prevent materials brittleness;

    • White-based light-color and smooth surface with high reflection, energy saving and anti-dust functions;

    • Use heat welding for the seam areas to form a reliable seamless waterproof layer.

    • Intermediate enhanced polyester mesh fabric to have high tensile strength, fatigue resistance and penetrating resistance suitable for mechanically attached roofing systems;

    • Excellent the same high and low temperature resistance as rubber materials which can keep flexible at -50° C and keep mechanical strength in high temperature;

    • Excellent chemical resistance to acids, bases, and restaurant exhaust emissions;

    • Dimension stability;

 

5. How to Constrution TPO sheet?

For Mechanically Attached Roofing System

Before application, spread TPO membranes on substrate in advance. Install TPO membranes perpendicular to steel deck ribs on the substrate without distortions according to the flange. The overlapping width is 120 mm. The minimum overlapping distance of membrane short side direction is 50 mm. Fasteners are installed according to designed position. Hot-air welding is adopted for laps with 40 mm welding width.

For Fully Adhered Roofing System

Before application, spread TPO membranes on substrate in advance. Install TPO membranes on the substrate without distortions according to the flange. The overlapping width should be more than 50 mm. Hot-air welding is adopted for laps with 40 mm welding width. Professional adhesives need to be used on both underside and substrate surfaces to adhere and maintain.

For Ballasted Roofing System

Before application, spread TPO membranes on substrate in advance. Install TPO membranes on the substrate without distortions according to the flange. The overlapping width should be more than 50 mm. Hot-air welding is adopted for laps with 40 mm welding width.

 

6.Storage

PMT-TPO material should be stored in well-ventilated place and avoid being exposed to the sun or rain. The temperature in stored places can not be higher than 45° C. It only can be put horizontally in five-level. It has to be avoided acid, alkali, oil and organic solvents. The shelf life is 1 year.

 

7. Transportation

PMT-TPO material should avoid inclination or lateral drift during transportation. When necessary, covering with felted fabric.

 

8. Attentions

    TPO membranes reflect heat and light, wearing protective clothing (long-sleeved shirt, long-barreled trousers), and wearing a filter to protect the skin and eyes from UV-induced damage.

    Security measures for roof perimeter are necessary when application. Sheet surface is slippery when wet, taking care to avoid slide.

    Sealants and adhesives are flammable containing solvents. They will be dangerous when exposure to heat, even have the possibility to catch fire and explode.

    Sealants, adhesives, cleaners should be avoided contacting with skin and eyes.

    No smoking during application.

 

9.Certificate:

Meanwhile, it has obtained FM certificate of the US, CE certificate of EU, and Gost-R certificate of Russia with its more stable properties and excellent performance.

Q:What is the difference between construction non-vulcanized waterproofing membrane and vulcanized waterproofing membrane?
The vulcanized waterproofing membrane is characterized in that it consists of a vulcanized butyl rubber, a softening agent, a hard acid and a filler, wherein the parts by weight are butyl rubber: softening agent: hard acid: filler = 1 : 0.003-0.015: 0.006-0.036: 0.32-0.73, wherein the softening agent uses a mechanical oil, which can also be made into a high-strength waterproofing membrane by sandwiching a layer of the web between the two layers of the waterproofing membrane.
Q:On the roof of the waterproofing membrane paving the direction of what are the requirements
 For the vibration of the roof, such as the use of parallel roof ridge direction asphalt waterproofing membrane, under the influence of vibration, easy to slip the membrane waterproof layer. And therefore should be vertical roof ridge direction. But the high strength of synthetic polymer film can not be limited.
Q:What should the attention of the membrane waterproof construction?
(1) grass-roots coating on the base layer of treatment agent, requiring thin and uniform, generally dry, when the sticky hand can be paving the membrane;
Q:Do you know how many square meters of waterproofing membrane to send a set of tests?
Modified asphalt polyethylene tire waterproofing membrane: any volume in the distance 2m at the end of the interception of 1m full-width coil sample 2, 1000 volumes for a group, the lack of a group also
Q:Whether the polyester waterproofing membrane can be used for roofing waterproofing
2, roof waterproofing is not just a layer of waterproof membrane, according to the design of the coating is usually used waterproof layer + polyester membrane waterproof layer;
Q:What is rigid waterproof, flexible waterproof?
1, rigid waterproof means that: waterproof layer by the tensile force is greater than the tensile strength of waterproof materials (including settlement deformation, temperature deformation, etc.), waterproof layer of brittle cracking caused by leakage of water, known as rigid waterproof. (Especially the "water leakage" waterproof layer), waterproof concrete mortar waterproof layer, thin layer of inorganic rigid waterproof layer (such as "water leakage" waterproof layer), and so on.
Q:What is the PEDM waterproofing membrane material?
Process: clean up the grassroots → brushing the primary treatment agent → additional layer of treatment → film paste surface coating → base surface coating → coil bonding, exhaust, compaction → coil joint bonding, compaction → roll Material end of the head and edge processing → do protection.
Q:How to choose waterproof membrane
Third, from the physical quality of strict quality off From the appearance of visual inspection can only distinguish the composite tire coil, but failed to solve the selected products meet the quality requirements, which requires users to have the ability to test the technical institutions, according to the corresponding product standards for soluble content The physical properties of the factory test, with the soluble content of the project to control the product contains the amount of asphalt and modifier, but also to reveal the product used in the real face of the fetus can determine whether it is consistent with the product mark.
Q:What is sbs, app modified asphalt waterproofing membrane
Their characteristics and differences: First, SBS modified asphalt waterproofing membrane (polyester tires): SBS modified asphalt waterproofing membrane is SBS rubber modified petroleum asphalt cited as the invasion coating, polyester fiber non-woven , Jute cloth, glass fiber mats were made for the fetal base, the plastic film for the anti-sticking isolation layer, the selection, ingredients, eutectic, invasion, composite molding, curling and other processes processing production. Such as building dragon TJ-242 SBS elastomer modified asphalt waterproofing membrane. Features: The use of polyester felt (filament polyester non-woven) mechanical properties, water resistance, corrosion resistance is also very good; elastic and low temperature performance has improved significantly, the effective range of (-25 ~ 100) ℃; Excellent fatigue resistance. Use: for high-level and high-rise buildings of the roof of the single-layer laying and composite use, can also be used for basement and other waterproof and moisture, more suitable for the northern cold areas and structural flexibility of the building waterproof.
Q:Sbs modified asphalt waterproof membrane polyester type Ⅰ type Ⅱ how to distinguish
SBS modified asphalt waterproofing membrane is SBS rubber modified petroleum asphalt cited as the invasion coating, polyester fiber non-woven fabrics, jute cloth, fiberglass mats were made for the fetal base, the plastic film for the anti-sticking isolation Layer, by the selection, ingredients, eutectic, invasion, composite molding, curling and other processes processing production.
