Saran

Saran is the generic name for fibers made from synthetic copolymers that are greater than 80% vinylidene chloride. The fiber is formed through emulsion copolymerization of vinylidene chloride with lesser amounts of vinyl chloride using a free radical catalyst, and the precipitated copolymer is melt spun into the fiber  [Pg.105]

The fiber has a tenacity of 1-2 g/d (9-18 g/tex) and elongations at break vary from 15% to 30% It is a soft flexible fiber of high density [Pg.106]

Vinylidene chloride and vinyl chloride lead to the copolymer known as Saran. Other commercial copolymers are produced from vinyl chloride and acrylonitrile (Dynel), and from maleic anhydride and styrene. [Pg.1016]

Poly(vinylidene chloride). Poly(viayHdene chloride) [9002-85-1] (PVDC), most of which is produced by Dow Chemical, is best known in its saran or PVC-copolymerized form (see Vinylidene chloride and poly(VINYLIDENE chloride)). As solvent or emulsion coating, PVDC imparts high oxygen, fat, aroma, and water-vapor resistance to substrates such as ceUophane, oriented polypropylene, polyester, and nylon. [Pg.452]

Saran film is used to wrap cheese and occasionally for vertical form/fiU/seal chub packaging of sausage and ground red meat. Mostly it is used as the high barrier component of laminations not containing aluminum foil. It is rarely used alone in commercial packaging because it is difficult to seal. [Pg.452]

Among nonmetallic materials, glass, chemical stoneware, enameled steel, acid-proof brick, carbon, graphite, and wood are resistant to iodine and its solutions under suitable conditions, but carbon and graphite may be subject to attack. Polytetrafluoroethylene withstands Hquid iodine and its vapor up to 200°C although it discolors. Cloth fabrics made of Saran, a vinyHdene chloride polymer, have lasted for several years when used in the filtration of iodine recovered from oil-weU brines (64). [Pg.364]

Vinylidene chloride copolymers were among the first synthetic polymers to be commercialized. Their most valuable property is low permeabiUty to a wide range of gases and vapors. From the beginning in 1939, the word Saran has been used for polymers with high vinylidene chloride content, and it is still a trademark of The Dow Chemical Company in some countries. Sometimes Saran and poly (vinylidene chloride) are used interchangeably in the Hterature. This can lead to confusion because, although Saran includes the homopolymer, only copolymers have commercial importance. The homopolymer, ie, poly (vinylidene chloride), is not commonly used because it is difficult to fabricate. [Pg.427]

Although Saran is a generic name for VDC copolymers in the United States, it is a Dow trademark in most foreign countries. Other trade names include Daran (Hampshire Chemical Corporation) and Serfene (Morton Chemical) in the United States, and Haloflex (Zeneca Resins), Diofan (BASE), Ixan (Solvay SA), and Polyidene (Scott-Bader) in Europe. The monomer is of particular economic interest because it is only 27 wt % hydrocarbon. In addition, B. E. Goodrich Chemicals (GEON) supply non-barrier VDC copolymers. [Pg.440]

The traditional definition of a barrier polymer requited an oxygen permeabihty less than 2 nmol /(m-s-GPa) (originally, less than (1 comil)/(100 in. datm)) at room temperature. This definition was based pardy on function and partiy on conforming to the old commercial unit of permeabihty. The old commercial unit of permeabihty was created so that the oxygen permeabihty of Saran Wrap brand plastic film, a trademark of The Dow Chemical Company, would have a numerical value of 1. [Pg.488]

Unplasticized polyvinyl chlorides (type I) have excellent resistance to oxidizing acids other than concentrated and to most nonoxidizing acids. Resistance is good to weak and strong alkahne materials. Resistance to chlorinated hydrocarbons is not good. Polyvinyhdene chloride, known as Saran, has good resistance to chlorinated hydrocarbons. [Pg.2457]

Phenolic asbestos, general-purpose polyester glass, Saran, and CAB are adversely affected by alkalies. And thermoplastics generally show poor resistance to organics. [Pg.2461]
