Olefin is a group of hydrocarbons composed of only carbon and hydrogen atoms. The one exception to this is a type of olefin called "Comfortouch" by Shaw. Rugs manufactured from these fibers are available in a wide range of … This property allows polypropylene to be used as containers that can be used to store chemicals. In the industrial scale productions, these polymers are made in the presence of a catalyst such as Ziegler-Natta catalyst. Polypropylene (Olefin) Carpet Safety Olefin is not as durable as nylon, but it's chemically inert and resists acid and bleach well. Polypropylene (PP) or polypropene is a thermoplastic polymer which is made by the polymerization of propylene. Aliphatic structures are called acyclic olefins. Polypropylene fibers are made from propylene molecules whereas olefin fibers can be produced using olefin molecules such as ethylene and propylene. I have also noticed a shift in the major brand name rug and carpet manufacturers, they are also using polypropylene and olefin in their latest generation of area rugs, so just because it may have a good brand name it does not mean you will get a good quality area rug. Sự khác biệt chính - Olefin vs Polypropylene Olifin và polypropylene là hai loại sợi công nghiệp được sử dụng rộng rãi cho nhiều ứng dụng. It is made out of propylene monomers. Olefin: Olefin is a group of hydrocarbons that is composed of only carbon and hydrogen atoms. Cyclic structures are known as cyclic olefins. In bulk process, the polymerization takes place in liquid propene; later, the solid polymer particles are separated from the liquid and, propene is recycled. Olefin's advantages are its strength, colourfastness and comfort, its resistance to staining, mildew, abrasion, and sunlight, and its good bulk and cover. Lazonby, John. Home » Science » Chemistry » Industrial Chemistry » Difference Between Olefin and Polypropylene. Polypropylene: In general, polypropylene is a flexible, low dense and tough material. In the carpet industry, the terms are typically used interchangeably. COMMERCIAL Polyolefin Fibers. Olefin dries very rapidly. The names alkene and olefin represent the same group of compounds. 1. Olefin: Olefins have both sp2 hybridized and sp3 hybridized carbon atoms. Presence of Double Bonds. Perbedaan Utama - Olefin vs Polypropylene. It is also used in automotive parts in some equipment; for example, interior fabrics used in or on kick panel, package shelf, seat construction, truck liners and load decks. Most of the properties of polypropylene are quite similar to polyethylene. Olefins are alkenes. “Polypropylene” By Ed (Edgar181) – Own work (Public Domain) via Commons Wikimedia. Major manufacturers include Fiber Vision, ASF, Nan Ya Plastics, Mitsubishi Rayon, Radici Group, Teijin, Honeywell, Toyobo, Lear Corp., Sinopec and Indorama Ventures.. Created in the 1950's, Olefin (Polypropylene and Polyethylene are types) is a man made fiber that is created from plastic pellets that are melted, and then forced through a spinneret, which resembles a showerhead, creating the fiber, which is then spun into yarn and woven into fabric. Olefin adalah alkena. Olefin has several distinct characteristics as compared to other synthetic carpet fibers. It’s also known as polypropylene, a type of thermoplastic used to make a wide range of household products, medical devices and more. Olefin is known to have a moderate shi… Olefin, the trade name for the textile that is produced out of polypropylene fibre, was developed by Italian chemist Giulio Natta in 1957 in Italy. Olefin has some promising qualities such as strength, colorfastness, and comfort. Currently, this fiber makes up about 16% of the total fiber production. This is the key difference between Olefin and Polypropylene. However, since it is not as resilient as other fibers, polypropylene is better suited to low-profile loop (Berber) carpets in which there is less need for superior resiliency. There are many different applications of olefins due to their important chemical properties such as chemical resistance and high melting point. By the number of double bonds present in the chemical structure, olefins can be named as monoolefins, diolefins, triolefins, etc. Ada banyak aplikasi olefin yang berbeda karena sifat kimianya yang penting seperti ketahanan kimia dan titik lebur yang tinggi. “Olefin.” Encyclopædia Britannica, Encyclopædia Britannica, inc., 21 Apr.
