TPO Waterproof Roofing Membrane

  • Thickness: 1.2mm/1.5mm/2.0mm
  • Width: 2.05m
  • Length: 20m or as request
Introduction

TPO, the abbreviation of thermoplastic polyolefin, is made with the dynamically vulcanized EPDM thermoplastic EPDM, the main ingredients of the composition of PP and EPDM. TPO mainly contains carbon atoms and hydrogen atoms and does not contain any plasticizers and chlorine elements. It is a beautiful, long-lived environment-friendly product. 


Features 

 It’s easy to install with good system integrity, few accessories.
 Excellent tensile strength, tearing resistance and penetration resistance performance.
 No plasticizer. They have been tested as having excellent resistance to thermal aging and ultraviolet, durable and exposed.
 Hot-air welding. The peel strength of joint is high.
 Fast welding speed.
 Environment friendly, 100% recycled, without chlorine.
 Durable hot welding performance and easy to repair.
 Smooth surface, no fading and pollution.

 
Applications
Widely used in the roofing and underground constructions of industrial and civil buildings. For different bases and constructions, PVC membranes are installed mechanically-attached, fully-adhered or ballasted.



Packing
Rolled with hard materials and packed with plastic bags or woven bags.


Storage
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.

Transport
TPO material should avoid inclination or lateral drift during transportation. When necessary, it covered with felted fabric.


Application Methods
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.


Technical Data Sheet
According to the constituent, it can be divided into
1. homogeneous sheet (code: H),
2. fiber-backed sheet (code: L),
3. sheet internally reinforced with fabric (code: P),
4. sheet internally reinforced with fiber glass (code: G),
5. sheet with fabric backing and reinforcement of glass fiber (code: GL). 




Attentions
 TPO membranes reflect heat and light. Be sure to wear protective clothing (long-sleeved shirt, long-barreled trousers), and wear a filter to protect the skin and eyes from UV-induced damage.
 Security measures for roof perimeter are necessary during application. Sheet surface is slippery when wet and therefore, take care to avoid slide.
 Sealants and adhesives are flammable containing solvents. They will be dangerous when exposed 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.
