polipropilen

التركية - الإنجليزية

تعريف polipropilen في التركية الإنجليزية القاموس.

polypropylene

A fabric of fibers made from any of these resins

A thermoplastic similar to polyethylene but stiffer & having a higher softening point (temperature)

A tough, light-weight rigid plastic made by the polymerization of high-purity propylene gas in the presence of an organometallic catalyst at relatively low pressures and temperatures

Similar to polyethylene, but stronger and having a higher temperature resistance

Plastic No smoke when exposed to a flame, drips like a candle and smells of burnt oil Light weight with high impact strength Joined by butt welding, fusion welding or plastic welding Suitable for working temperatures between 0 and 90oC, suitable for handling foodstuffs High purity polypropylene is available and is sometimes used in marine hatcheries (particularly for shellfish) where water purity can be critical to correct larval development Thermal expansion is higher than most other plastic materials The requirement for heat fusion welding usually prevents polyethylene pipe form being routinely used, as solvent weld plastic such as UPVC and ABS are easier and quicker to install Polyethylene sheeting is sometimes used for the construction of cheap tanks and vessels such as biofilters

a thermoplastic resin made by the polymerization of propylene - used for films, fibres, or moulding materials. Also known as polypropene

A common type of plastic produced from propylene and used in the manufacture of pipes and tubing, household goods and medical equipment

A type of plastic used in banners, noted for its flexibility at low temperatures and its resistance to chemicals

Thermoplastic resins made by polymerizing propylene [CH3CHCH2] and in the case of copolymers with monomers, with suitable catalysts, generally aluminum alkyl and titanium tetrachloride mixed with solvents The monomer unit in polypropylene is asymmetric and can assume two regular geometric arrangements: isotactic, with all methyl groups aligned on the same side of the chain, or syndiotactic, with the methyl groups alternating All other forms, where this positioning is random, are called atactic Commercial polypropylene contains 90-97% crystalline or isotactic PP with the remainder being atactic Most processes remove excess atactic PP This by-product is used in adhesives, caulks, and cablefilling compounds Major applications of commercial PP are found in packaging, automotive, appliance and carpeting markets

A manufactured fiber characterized by its light weight, high strength, and abrasion resistance Polypropylene is also good at transporting moisture, creating a wicking action End-uses include activewear apparel, rope, indoor-outdoor carpets, lawn furniture, and upholstery

A stiff, heat resistant, chemically stable plastic Common uses in preservation include sleeves for 35mm slides or films and containers

a light, thermoplastic resin used in packaging, coating, pipes, and tubes Top

A thermoplastic material similar to polyethylene but somewhat stiffer and with a higher softening point (temperature)

excellent chemical resistance, resistant to sulphur-bearing compounds, lightweight, good tensile strength and saltwater resistance Stronger and more rigid than polyethylene with a higher functioning temperature (190o F), polypropylene is popular as a material for tubular products, such as P-traps, because of its high chemical resistance

A form of plastic, often used for food lids and food containers, that is seldom recycled

A plastic generally considered safe by ISO for use with photographs However, many of these plastics are treated with thin coatings to modify their chemical and surface properties, so polypropylene products should still pass the PAT

In its pure form, a chemically stable plastic material Used in film form as for polyethylene Used in sheet form for boxes, folders and such A cheaper alternative to polyester film

A plastic based material used primarily for speaker cones due to its rigidity, damping and resistance against harsh environmental conditions 1

A cousin of polyethylene' with generally similar properties' but stronger and having a higher temperature resistance
