    What Is PP?

    Polypropylene or polypropene (PP) is a thermoplastic polymer, used in a wide variety of applications, including food packaging, textiles, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components, and polymer banknotes. An addition polymer made from the monomer propylene, it is rugged and unusually resistant to many chemical solvents, bases and acids.   Chemical & Physical Properties Most commercial polypropylene has an intermediate level of crystallinity between that of low density polyethylene (LDPE) and high density polyethylene (HDPE); its Young's modulus is also intermediate. Although it is less tough then HDPE and flexible than LDPE, it is much more brittle than HDPE. This allows polypropylene to be used as a replacement for engineering plastics, such as ABS. Polypropylene is rugged, often somewhat stiffer than some other plastics, reasonably economical, and can be made translucent when uncolored but not completely transparent as polystyrene, acrylic or certain other plastics can be made. It can also be made opaque and/or have many kinds of colors. Polypropylene has very good resistance to fatigue, so that most plastic living hinges, such as those on flip-top bottles, are made from this material. Very thin sheets of polypropylene are used as a dielectric within certain high performance pulse and low loss RF capacitors. Polypropylene has a melting point of (160 degrees Celsius). Many plastic items for medical or laboratory use can be made from polypropylene which is autoclavable so that it can with stand the heat in an autoclave. Food containers made from it will not melt in the dishwasher, and do not melt during industrial hot filling processes. For this reason, most plastic tubs for dairy products are polypropylene sealed with aluminium foil (both heat-resistant materials). After the product has cooled, the tubs are often given lids of a cheaper (and less heat-resistant) material, such as LDPE or polystyrene. Such containers provide a good hands-on example of the difference in modulus, since the rubbery(softer, more flexible) feeling of LDPE with respect to PP of the same thickness is readily apparent. Rugged, translucent, reusable plastic containers made in a wide variety of shapes and sizes for consumers from various companies such as Rubbermaid and Sterilite are commonly made of polypropylene, although the lids are often made of somewhat more flexible LDPE so they can snap on to the container to close it. When liquid, powdered, or similar consumer, products come in disposable plastic bottles which do not need the improved properties of polypropylene, the containers are often made of slightly more economical polyethylene, although transparent plastics such as polyethylene terephthalate are also used for appearance. Plastic pails, car batteries, wastebaskets, cooler containers, dishes and pitchers, are often made of polypropylene or HDPE, both of which commonly have rather similar appearance, feel, and properties at ambient temperature.   MFI (Melt Flow Index) identifies the flow speed of the raw material in the process. It helps to fill the plastic mold during the production process. The higher MFI increases, the weaker the raw material gets. It also has Copolymer and Random Copolymer. Copolymer helps stiffness of the PP (Polypropylene). Random Copolymer helps transparent look. Copolymer is more expensive than Homopolypropylene. Random Copolymer is even higher than copolymer PP. A rubbery PP can also be made by a specialized synthesis process, as discussed below. Unlike traditional rubber, it can be melted and recycled, making it a thermoplastic elastomer.   The Best Solution Thermopipe has earned a good reputation throughout the Middle East as a more flexible and efficient alternative to traditional materials such as copper and steel. Thermopipe : Polypropylene Random Copolymer. (PPRC) piping has been approved to be ideal for plumbing, heating, air conditioning systems and for a wide range of industrial and medical uses. Now, the system has been further improved with the addition of a full range of PPRC fittings that can be "Polywelded" to Thermopipe to create fully watertight systems, even under the most severe conditions of use. Thermopipe has been approved from the Ministry of Public Works & Housing in Jordan in the Central heating Code: item number 5/2/1 & item 8/3/5 d, year 1990.   Application Fields Thermopipe system can be used for: - Hot and cold potable water piping networks in residential and commercial building. i.e. hospitals, hotels, offices, school buildings etc. - Chilled water networks in air conditioning systems, as an effective light weight and corrosion free substitute for steel pipes. - Transportation of wide range of chemicals in the industry. - Irrigation systems for gardens. - Piping networks for rainwater utilization systems. - Piping networks for swimming pools facilities. - Compressed air installations. - Piping networks for solar plants.   Characteristics NO CORROSION Thermopipe withstands all types of water hardness and withstands acids and alkaline substances cross a wide concentration and temperature range. (See table of Chemical Resistance page 24). LESS PRESSURE LOSS The smooth internal finish of Thermopipe creates no disturbance to flow and does not allow sediment to build up and reduces pressure. The pressure changes caused by opening and closing the cocks is sufficient to wash off any sediments. (Pressure loss data is given on page: 10). LESS NOISE The elasticity of polypropylene is 257 times higher than steel. A Thermopipe system will absorb water hammers which cause annoying vibration and noise in the buildings. LONG-LIFE- TIME The molecular structure of copolymers and special additives ensure a high mechanical resistance and a long life, depending on operating temperature and pressure. A Thermopipe system can be expected to last up to 50 years. FROST RESISTANCE Thermopipe will not burst in a cold weather the elasticity of the material allows the pipe to increase its section according to the volume of the frozen liquid inside it. ABRASION RESISTANCE Thermopipe has four times the abrasion resistance of metal piping, allowing higher water velocities, (up to 7m/sec) without corrosion problems. DAMAGE RESISTANCE Being made from a non-rigid material, A Thermopipe system does not suffer major damage as a result of building movement. Thermopipe is recognized by the Commission of International Engineering as being fit for use in seismic areas.. HYGINEIC AND NONTOXIC Easy Workability Due to the density of just 0.898 g/cm3, pipes and fittings are very light. Combined with the wide range of fittings available, this enables complete installations to be made easily and safely, with considerable time savings compared to conventional products. Thermopipe system is non toxic in accordance with current international standards.   Energy Saving Thermopipe systems reach their operating temperature much faster than metal piping systems. Less energy is wasted Heating the pipe and less insulation is needed.   Low Thermal Conductivity Wetherring of PPR pipe The material's high level of thermal insulation guarantees low heat loss on the part of the fluid transported. This means minimal drop in temperature between the hot water source and delivery points, with consequent energy saving.
