Yuru TPO waterproofing membrane

Description:

The full name of TPO membrane is thermoplastic polyolefin. It entered the U.S. market in the 1980s. In the early 1990s, TPO materials were used in roof waterproofing projects in a mechanically fixed paving method. The material is specially formulated without any added plasticizers and does not contain chlorine. Compared with various thermoplastic waterproof materials, it has unique low-temperature flexibility, aging resistance, stable physical properties and environmental protection, easy welding, and forms a watertight whole. Therefore, TPO waterproof membrane has become popular in the waterproof material market of industrially developed countries such as the United States and Europe. develop rapidly.

TPO waterproof membrane is a thermoplastic polyolefin (TPO) material that uses advanced polymerization technology to combine ethylene propylene (EP) rubber and polypropylene as the base material, and uses polycool fiber mesh fabric as the carcass reinforcement material. It is composed of sheet-shaped rollable waterproof materials made using advanced processing technology. This material has both the long-term weather resistance and durability of ethylene propylene (EP) rubber and the weldability of polypropylene. A layer of polycool fiber fabric is sandwiched between two layers of TPO materials to enhance its physical properties and improve its breaking strength. , fatigue resistance and puncture resistance. The TPO on the upper surface of the reinforcement layer has a highly reflective, mainly white, light-colored smooth surface. Since it does not contain chlorine, it is beneficial to environmental protection and construction safety.

Product Categories:

According to product composition, it is divided into: homogeneous thermoplastic polyolefin waterproofing membrane (H), thermoplastic polyolefin waterproofing membrane with fiber backing (L), and fabric-reinforced thermoplastic polyolefin waterproofing membrane (P).

Features：

·TPO membrane uses advanced polymerization technology to combine ethylene-propylene rubber and polypropylene, combining the excellent weather resistance and durability of ethylene-propylene rubber with the weldability of polypropylene.

·Special formula technology does not require the addition of any plasticizers that can easily make the material brittle. It has high flexibility and does not cause the phenomenon of general polyolefin materials becoming brittle due to plasticizer migration. It maintains long-term waterproof function. .

·There is a layer of polyester fiber fabric sandwiched in the middle, which provides the roll with high tensile properties, fatigue resistance, and puncture resistance, and is suitable for mechanically fixed roof systems.

·Excellent high and low temperature resistance, maintaining flexibility at -40°C and mechanical strength at higher temperatures.

·Chemical resistance, resistance to acid, alkali, salt, animal oil, vegetable oil, lubricating oil corrosion, resistance to the growth of algae, mold and other microorganisms.

·Heat-aging resistance and good dimensional stability. Light color, mainly white, with smooth surface, high reflectivity, energy saving effect and pollution resistance.

·The ingredients do not contain chlorinated polymers or chlorine. There is no chlorine reaction during welding and use, and it is harmless to the environment and human health.

·The overlap is thermally welded to form a high-strength sealing layer.

Applications:

TPO waterproof membrane is suitable for exposed or non-exposed roof waterproofing layers of buildings and underground waterproofing of easily deformed buildings.

1. Roof waterproofing: TPO waterproof membrane can be widely used for waterproof protection of various roof structures, including flat roofs, sloped roofs, special-shaped roofs, etc. Rollable strips (1.2 meters wide) or shapeable strips (2.1 meters wide) can be used wide) two specifications to choose from.

2. Basement waterproofing: TPO waterproof membrane can perfectly meet the needs of basement waterproofing projects, including basic waterproofing, exterior wall waterproofing, interior wall waterproofing, floor waterproofing, etc. It can effectively prevent moisture, mildew, and leakage.

3. Pond waterproofing: TPO waterproof membrane has excellent corrosion resistance and chemical resistance, which can prevent leakage, penetration and leakage of various types of ponds, pools and other water bodies, ensuring the quality and service life of the water body.

4.Tunnel waterproofing: TPO waterproof membrane can withstand high-intensity wind, water pressure and earth pressure, and can achieve multiple functions such as tunnel waterproofing, sound insulation, heat insulation, and fire prevention, providing protection for tunnel construction and use.

01 Construction points：

[TPO membrane mechanical fixed roofing system]

TPO membrane roofing systems are generally mechanically fixed. That is, the TPO membrane is laid on the base layer (or the fixed insulation board), and in the adjacent lower membrane overlap area, it is fixed to the base layer with mechanical fastening screws and fixed washers. The overlap is welded by hot air welding to connect the membranes into an integrally sealed waterproof layer. The outer edges of the joints should be sealed with sealant according to project needs.

[Construction Points of Mechanical Fixed Level System]

Base layer: The base layer for laying TPO membrane should be solid, flat, clean and dry. The deformation joint area is first sealed according to the design, and TPO membrane is added as an additional layer.

·TPO membrane pre-laying: Lay the membrane according to the predetermined position. It should be smooth and straight, without twisting or overlapping of adjacent membranes.

·Mechanical fixation of the lower membrane in the overlap area.

·Thermal welding of the overlap area. The width of the overlap area of adjacent coils is generally 150mm (long side). The upper coil covers the mechanical fasteners of the lower coil. Clean the welding area before and after welding the overlap, and then use Use a manual welding gun (or automatic welding machine) to weld evenly.

·Additional waterproofing of typical details: Typical details such as the yin and yang angles on three sides, pipe edges and roots, use non-reinforced TPO water-injection substrate as an additional waterproof layer, and are welded with the main waterproof layer using hot air welding. Vertical facade TPO roll ends are mechanically fixed with metal battens. It is advisable to embed water-stop sealing material on the base layer before fixing, and finally seal it with sealing paste.

[TPO membrane bonding system]

The base layer and the bottom surface of the coil are fully coated with the base adhesive (it can also be applied by dots, strips or empty paving according to the actual situation). Adjacent coils overlap each other and are overlapped by hot air welding. The edges are sealed with sealant. closed. The bonding method is suitable for all types of buildings, construction techniques and key process operations on cement concrete bases, and is the same as all types of polymer waterproofing membranes bonded with adhesives.

02Matters need attention：

※During transportation, keep away from the sun and rain, keep away from fire sources, prevent collisions, and ensure that the packaging is intact.

※When storing the product, store it in a ventilated and cool place, and keep it away from fire sources.
