Description
CAPTEC FLEXPRUF 800 is a waterproofing sheet, consisting of thermoplastic polyolefin Compound resin materials as the base stock, reinforced with polyester mesh fabric.There have two kinds of thickness: 1.2mm and 1.5mm.

 
Where to use
Various roofing waterproof projects, such as industrial and civil buildings,
Mechanically attached waterproofing system.

 
Advantages
Weather resistance and durability; Excellent weld ability;
No any crisp agents to prevent materials brittleness;
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;
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.

Storage
FLEXPRUFE 800 TPO roofing membrane 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.

 
Transportation
FLEXPRUFE 800 TPO membrane should avoid inclination or lateral drift during transportation. When necessary, covering with felted fabric.

 
Application System
CAPTEC not only provides TPO waterproofing membrane, but also dedicates to integrated roofing systems. CAPTEC TPO single ply roofing waterproof system includes mechanically attached roofing system, fully adhered roofing system and ballasted roofing system. But FLEXPRUFE 800 TPO only can be applied by mechanically attached roofing system.

CAPTEC provide the completed line of compatible accessories and components, including fasteners, sealants, adhesives for membrane, cleansers, insulation, vapor retarders and flashing, etc.
Yuhong also provide economical and reliable roofing system designs for our customers according to their demands.

 
Application Methods
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.

 
Attentions
TPO roofing 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.
