| PVC-O laminar structure |
Twelve is the number of years that have passed since Molecor was founded. Molecor stood out in the water sector for the first time in its history among its many and very experienced competitors just one year after its foundation. The development of its exclusive Genuine Air System used for manufacturing PVC-O pipes, was the reason for this success.
The stir that this system caused in the industry was due to the fact that it showed an exclusive, novel and innovative way of applying the Molecular Orientation process to pipeline solutions. The use of air instead of boiling water is the main aspect that distinguishes and makes this technology more secure and costefficient in comparison to the rest of the existing manufacturing processes.
The incredible results obtained after applying the Molecors' Molecular Orientation process are obvious and have been demonstrated by the TOM® pipes and the ecoFITTOM® excellent mechanical properties. Thanks to their improved characteristics, both products present important benefits and advantages and have become the most efficient, safe and eco-friendly solutions currently existing on the market.

| TOM® PVC-O pipes |
The increase in their hydraulic capacity, their excellent response to water hammer, complete resistance to corrosion, which guarantees that the quality of the conveyed water remains always unaltered, and therefore, that it is completely suitable for human consumption, their lower weight, and consequently easier installation in comparison to the solutions made of other materials, are some of the TOM® pipes and ecoFITTOM® advantages. Apart from this, their incredible resistance to impact and optimal behavior at low temperatures are two of the characteristics by which they are highly recognized, being the second one specially taken into account in cold countries.
PVC-O Class 500, material of which Molecors' products are made, remains completely unaltered at low temperatures in fact, the PVC-O Class 500 not only maintains its mechanical properties in optimal conditions at low temperatures, but it also experiences an improvement of those as the temperature becomes lower. PVC-O strength increases as the service temperature is reduced. Hence, the ability of this material to withstand internal pressure is greater at temperatures below 20°C. Regarding expansion and contraction of PVC-O piping systems we could say that the potential consequences of larger expansion/contraction coefficients are offset by their lower stiffness as well as by their capacity to gradually reduce stress reactions through the phenomenon of stress-relaxation. This results in considerably lower ultimate reaction loads than those that result in metal piping for an equal temperature change.
The higher resistance to impact at low temperatures of TOM® pipes in comparison to that of the other solutions offered on the market has also been proved by tests such as the one carried out in Moscow by the Russian institute Mezhotraslevoy Institut Pererabotki Plastmass-NPO "Plastik". After submitting a DN200 mm TOM® pipe to an impact of 2 kg weight, thrown from a height of 2 m at a temperature of -40°C, it was observed that the pipe did not present absolutely any damage, complying satisfactorily with the requirements of the ISO 16422 Standard.
This result shows the effectiveness of the Molecors' exclusive Molecular Orientation process and justifies the fact that the TOM® pipes are currently presented as the best solution to be PVC-O laminar structure used for the conveyance of water under pressure, especially in cold areas where the percentage of leakages in the unions reaches up to 70. The poor quality and obsolescence of the water networks together with the lack of investment in their rehabilitation and the extreme climate conditions are the main reasons that explain the high rate of total water loss in these areas. In response to these problems the Molecor technology offers, in addition to its exclusive Molecular Orientation process, both, the Integrated Socket System, which produces the socket at the same time than the rest of the pipe guaranteeing the same properties in all the parts of the pipe, and the Integrated Seal System (+ISS), which enables to insert a rubber gasket inside the pipe in a completely automatic way, ensuring a complete watertight in the unions and guaranteeing a much more efficient management of the water resources.

| ecoFITTOM® PVC-O fittings |
The high degree of adaptability of this technology has enabled the company to develop and offer to the market a wide range of products (TOM® PVC-O pipes from DN90 mm up to DN800 mm and PVC-O fittings: bends, couplers, sliding couplers and reducers in different diameters) remaining intact in each product the numerous benefits and advantages that it brings.
The development of the 3163 and 3180 M-OR-P Systems and of the ecoFITTOM® technology, have been fundamental for achieving this large range of products. Among them we must highlight the DN800 mm TOM® pipes, the biggest one never ever manufactured before in PVC-O, and ecoFITTOM®, the first fittings in the world manufactured in this material. Aware of the several problems and difficulties existing in the different regions of the world (obsolescence and precariousness of the water networks, lack of investment, adverse atmospheric phenomenon, extreme temperatures to which some areas are exposed, etc.), and conscious of the growing and more and more exigent demand of the water sector, Molecor bets on continuous improvement through an uninterrupted process of Research and Development with the aim of offering solutions increasingly adapted to the particularities of each market.
