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:How to distinguish whether the waterproofing membrane is polyester tires?
Waterproof membrane requirements have good water resistance, stability of the temperature change (high temperature does not flow, no blistering, not confuse; low temperature does not brittle crack), a certain mechanical strength, extensibility and resistance to fracture, to There is a certain degree of flexibility and anti-aging and so on.
Q:Asphalt composite tire flexible membrane is SBS
SBS waterproofing membrane implementation of standards: GB 18242 (2008) "elastomer modified asphalt waterproofing membrane" Asphalt composite tire flexible membrane implementation of the standard: JCT 690 (2008) "asphalt composite tire flexible waterproofing membrane" Sometimes the composite tire coil also refers to several other rubber modified membrane.
Q:What is waterproofing membrane?
Classification The asphalt or polymer waterproof material impregnated in the carcass, made of waterproof material products, in the form of coil, known as waterproofing membrane. According to the main composition of different materials, divided into asphalt
Q:Waterproof basement is empty shop or full shop
Basement waterproof construction specification. Basement waterproof acceptance specification, to see their own.
Q:Why the roof of the waterproof membrane and insulation rock wool board to do between the isolation layer?
2, the insulation layer can be done on the waterproof above, according to the nature of insulation materials, insulation layer and waterproof layer can be set between the isolation layer or not set. If the waterproof layer on the laying of polystyrene foam board, do not need to do isolation layer; if the block of inorganic insulation materials, such as foam glass, waterproof layer should be set on the cement mortar protective layer; if the waterproof membrane to do Foam concrete or polyurethane block insulation, you can dry in the coil a linoleum for the protection of the isolation layer.
Q:SBS waterproofing membrane sub-class I and II when to use what level to use a secondary level
Classification: According to physical indicators are divided into: Ⅰ (-20 ℃), Ⅱ (-25 ℃) type two categories; According to the fetal base can be divided into: polyester tires, glass fiber tire two categories; according to the surface material can be divided Waterproof sheet
Q:SBs waterproof cold sticky how to do?
Waterproof membrane cold sticking method construction points: 1, grass-roots inspection, cleaning. Cold sticky paste, the grassroots must be clean, dry, moisture content in line with design requirements, or easy to cause paste is not strong and drums. Therefore, before the construction, the grass-roots surface of the protrusions should be eradicated, and dust debris and other completely clean.
Q:What are the requirements for the storage of waterproofing membranes?
Prohibited sun exposure, exposure easily deformed.
Q:What is the resistance type SBS waterproofing membrane?
The third is the combination of the above two principles. SBS resistant root puncture membrane has three kinds: 1, composite copper fetal base SBS modified asphalt waterproofing membrane. Mainly using copper tires to puncture strength, while copper ion drive plant roots. 2, copper foil tire SBS modified asphalt waterproofing membrane. Mainly the use of copper ion drive plant roots, while a certain anti-piercing strength. 3, SBS modified asphalt root resistant puncture waterproofing membrane. Mainly chemical resistance to root.
