HIGH QUALITYPMT THERMOPLASTIC POLYOLEFIN(TPO) WATERPROOF SHEET MATERIAL

Product Overview

Description

PMT-TPO is a waterproof sheet, consisting of thermoplastic polyolefin compound resin materials as the base stock, reinforced with fiber backing materials. There have two kinds of thickness: 1.2mm and 1.5mm.

 

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

Full adhered system for concrete substrate or mechanically attached systems.

 

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.

Yuhong 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.

 

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.

 

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.
