Research and Markets: Plasticizer Database - Developed To Contain Data Required In Plasticizers Application.DUBLIN, Ireland -- Research and Markets (http://www.researchandmarkets.com/reports/c8615) has announced the addition of Plasticizer Database to their offering The plasticizer database was developed to contain data required in plasticizers application. Attempts were made to include large number of plasticizers used in various sectors of industry to provide information for all users and to help in finding new solutions and formulations. Plasticizers included in the database can be divided into two categories: generic chemical name compounds and commercial plasticizers which are either mixtures of several components, industrial grades of particular compound, polymeric materials, or products having unknown, complex composition. The database contains solvents representing all chemical groups of materials which considered as plasticizers. In most cases, plasticizers differ from solvents by boiling point, which is above 250oC, but some plasticizers are used as temporary plasticizers or are expect to react with other components of mixture. These substances will not meet the boiling temperature standard but will still be included since they play role of plasticizers. The large number of the plasticizers and the data fields makes this database the most comprehensive database on plasticizers ever available in any source. The plasticizer database is divided into four general sections: General information, Physical & chemical properties of plasticizers, Physical & mechanical properties of plasticized materials, and Health, safety & environmental protection data. Information on the selected plasticizer can be accessed by clicking on any of the above tabs. The database has several hundred data fields to accommodate a variety of data available in source publications. The description of general sections below gives more detail on the composition of information. Each displayed information contains plasticizer name and its chemical structure. The data can be viewed on screen and printed in predefined format. In General information section the following data are displayed: name, CAS #, IUPAC IUPAC: see International Union of Pure and Applied Chemistry. name, Common name, Common synonyms, Abbreviations, Empirical Formula, Molecular mass, RETECS Number, EPA EPA eicosapentaenoic acid.

The most common is to search name. In this case, the program searches through the list of synonyms and proposes choices. Search allows to find plasticizers by typing the first letter or two of their name which moves list to the location of a searched compound. Plasticizers can also be searched by CAS number, empirical formula, or any other property, or simply by browsing the list. In addition to searching capability and viewing data on individual plasticizers, plasticizers can be sorted according to values of any property. This operation is accomplished by clicking the property tab and selection of the required search term from a pull-down menu. The operation returns a selection of plasticizers for which data exist for the selected property. The plasticizer property can be viewed on the screen and used for evaluation of plasticizer suitability for the chosen task or plasticizer selection for application as well as plasticizer comparison. The above description shows that operation of the database is so simple that it does not require any computer skills. The appropriate computer for database use is a PC-based computer with Pentium processor (or other processor of similar speed) having a screen with resolution of at least 600 by 800 operating under Windows 95 or higher. Program contains operation manual which explains further details of operation. In summary, the database is a very powerful tool, because it contains the most extensive data available on a large number of plasticizers. The database is an excellent companion to the Handbook of Plasticizers because data in the database do not repeat information or data included in the book. The number of data currently available makes presentation of the data in the traditional format of a printed book unsuitable for fast accessing of the information and in this case difficult to handle. The printed form of this database would require at least 4000 pages in a book format. This is several times larger volume than was available in any past book containing information on the plasticizer properties.
