What is the internal diameter of a Blue 63mm MDPE PE 80 pipe SDR11 -12 bar water pipe?
approximately 50mm internal diameter but you'll need to verify this with manufactures if you need it to be precise. For modelling purposes this will give you a rough idea.
What is yellow mdpe gas pipe?
MDPE is Medium Density Polyethylene. Used for underground gas lines. IE firepit or to an outdoor BBQ. Is most common. MDPE gas pipe CANNOT be used inside of any building. Outside use ONLY!
Can Yellow MDPE Gas Pipe be used for internal use?
I believe NOT I'm not qualified, but someone who is tells me that it cannot be used inside a building because of the risk that it would melt in the event of a fire and allow gas to escape - thus feeding the fire ! HTH
Is polyethylene a pure substance a homogeneous mixture or a heterogeneous mixture?
Polyethylene is a pure substance. Polyethylene is a semicrystalline homogeneous polymer with a molecular weigh profile based upon the production chemistry. Common forms include HDPE, MDPE, LLDPE, LDPE, UHMWPE, etc.
What is the density of PE?
0.8 HDPE is defined by a density of greater or equal to 0.941 g/cm3 MDPE is defined by a density range of 0.926-0.940 g/cm3 LLDPE is defined by a density range of 0.915-0.925 g/cm3 LDPE is defined by a density range of 0.910-0.940 g/cm3 VLDPE is defined by a density range of 0.880-0.915 g/cm3 Thank You, Manoj Agarwal Opulent Wires & Cables
Why is polythene used to make bags?
Plastic bags can be made of different polymer types such as: High-Density Polyethylene (HDPE) Medium-Density Polyethylene (MDPE) Low-Density Polyethylene (LDPE) Linear low-density polyethylene Higher density polyethylene polymers have stronger cross-links for linking large chains to another which is usually how plastic bags are able to stretch more and can hold heavier objects. Hence being stronger.
What are some physical properties of a plastic bag?
Most LDPE, MDPE and HDPE grades have excellent chemical resistance, meaning that it is not attacked by strong acids or strong bases. It is also resistant to gentle oxidants and reducing agents. Polyethylene burns slowly with a blue flame having a yellow tip and gives off an odour of paraffin. The material continues burning on removal of the flame source and produces a drip. Crystalline samples do not dissolve at room temperature. Polyethylene (other than cross-linked polyethylene) usually can be dissolved at elevated temperatures in aromatic hydrocarbons such as toluene or xylene, or in chlorinated solvents such as trichloroethane or trichlorobenzene
What has thermoplastic in it?
Thermoplastic has many applications, including consumer goods, machine parts, medical equipment and packaging and storage materials.AcrylicAcrylic, a polymer called poly(methyl methacrylate) (PMMA), is also known by trade names such as Lucite, Perspex and Plexiglas. It serves as a sturdy substitute for glass for such items as aquariums, motorcycle helmet visors, aircraft windows, viewing ports of submersibles, and lenses of exterior lights of automobiles. It is extensively used to make signs, including lettering and logos. In medicine, it is used in bone cement and to replace eye lenses. Acrylic paint consists of PMMA particles suspended in water.NylonNylon, belonging to a class of polymers called polyamides, has served as a substitute for silk in products such as parachutes, flak vests and women's stockings. Nylon fibers are useful in making fabrics, rope, carpets and strings for musical instruments. In bulk form, nylon is used for mechanical parts, including machine screws, gear wheels and power tool casings. In addition, nylon is used in the manufacture of heat-resistant composite materials.PolyethylenePolyethylene (or polyethene, polythene, PE) is a family of materials categorized according to their density and molecular structure. For example, ultra-high molecular weight polyethylene (UHMWPE) is tough and resistant to chemicals, and it is used to manufacture moving machine parts, bearings, gears, artificial joints and some bulletproof vests. High-density polyethylene (HDPE) is used to make milk jugs, margarine tubs and water pipes. Medium-density polyethylene (MDPE) is used for packaging film, sacks and gas pipes and fittings. Low-density polyethylene (LDPE) is soft and flexible and is used in the manufacture of squeeze bottles, sacks and sheets.PolypropylenePolypropylene (PP) is useful for such diverse products as reusable plastic containers, diapers, sanitary pads, ropes, carpets, plastic moldings, piping systems, car batteries, insulation for electrical cables and filters for gases and liquids. In medicine, it is used to repair hernias and to make heat-resistant medical equipment. Polypropylene sheets are used for stationery folders and packaging and storage boxes.PolystyrenePolystyrene is manufactured in various forms that have differing applications. Extruded polystyrene (PS) is used in the manufacture of disposable cutlery, CD and DVD cases, plastic models of cars and boats, and smoke detector housings. Expanded polystyrene foam (EPS) is used in making insulation and packaging materials, such as the "peanuts" and molded foam used to cushion fragile products. Extruded polystyrene foam (XPS), known by the trade name Styrofoam, is used to make architectural models and drinking cups for heated beverages. Polystyrene copolymers are used in the manufacture of toys and product casings.Polyvinyl chloridePolyvinyl chloride (PVC) is a tough, lightweight material that is resistant to acids and bases. Much of it is used by the construction industry, such as for vinyl siding, drainpipes, gutters and roofing sheets. It is also converted to flexible forms with the addition of plasticizers, thereby making it useful for items such as hoses, tubing, electrical insulation, coats, jackets and upholstery. Flexible PVC is also used in inflatable products, such as water beds and pool toys.TeflonTeflon is the brand name given by DuPont Corp. for a polymer called polytetrafluoroethylene (PTFE), which belongs to a class of thermoplastics known as fluoropolymers. It is famous as a coating for non-stick cookware. Being chemically inert, it is used in making containers and pipes that come in contact with reactive chemicals. It is also used as a lubricant to reduce wear from friction between sliding parts, such as gears, bearings and bushings.Taken from "eHow"
