POLYMAT

POLYMAT DKI, Deutsches Kunstoffinstitut and Fachinformations2entmm Chemie GmbH data on commercially available plastic materials... 

Plastics Institute) established the materials database called Polymat. This program brings greater availability into a plastics market in which a general perspective is becoming increasingly difficult to obtain. This database contains information on plastics and elastomers, supplying about thirty to fifty properties for each material. Initially some six thousand plastics, from about seventy manufacturers, were stored. 

The concept of the Polymat database was based on the following criteria (1) the data-base is neutral, independent of raw-material manufacturers (2) anyone can use the database (3) all the products on. the European market should, if possible, be included (4) since testing is carried out in accordance with a variety of different international standards, the relevant standard, as well as the testing conditions, is registered (5) during the search, all properties should be capable of being linked with one another as desired and (6) the sources used for the database are the technical data sheets and additional information supplied by raw-material manufacturers, and various lectures, publications, and measured data from different institutes. 

In order for such an extensive project to remain manageable, certain requirements were necessary. Initially the data were confined to TPs, TSs, TPEs, and casting plastics. To be included in this group were the TSEs, reinforced plastics, foams, semifinished products, and others. Polymat completed its initial work in 1989. New plastics products on the market and updated additional information on existing products are continually added. Data no longer available are still accessible to the user in a memory file. 

In order to understand the possibilities of these two databases, a comparison can be made of a central database like Polymat and Campus. The Polymat central database provides the following (1) all the products of the various firms represented are included (2) the search is independent of the manufacturers and can be performed for all the products of all the manufacturers (3) available are not only the values contained in the list of basic values but other data specified in such standards as DIN, ASTM, and BS (although a search can nevertheless be confined to products whose data conform to the list of basic values) (4) the information is presented only once and is then maintained centrally and (5) a selection can be made between a greater number of materials and manufacturers. 

When Polymat was being established, it was necessary to decide on whether to charge the material manufacturer but not the user, or make no charge to the manufacturer but charge the user. DKI chose not to charge the user. 

With regard to the common European market, the European Economic Community (EEC) has undertaken numerous activities concerned with materials and material information systems. In one demonstration program for material databases eleven such databases from various countries in the EEC are being cooperatively developed with joint standards for terminology, data presentation, database access, and the user interface of search commands, aids, and menus. For the materials class of plastics, Polymat was selected to participate in this cooperative work. Interesting developments occur from which the users of central material databases in the entire EEC area can benefit.

Remarks also available-POLYMAT light as a version with less data for less costs with direct access to the full version via internet... 

POLYMAT light POLYMAT light Materials Data for Plastics is a manufacturer independent, materials database for plastics and contains properties of thermoplastics, thermoplastic elastomers and blends. In total, data from approximately 13,000 commercial products of 170 manufacturers are available products and data can be retrieved via searching in 35 different numerical properties and 15 text fields. 

POLYMAT light can be used for time saving and comprehensive selection of materials according to a customer s application profile employment of reasonably priced alternative materials with comparable properties in plastics manufacture searching for alternative manufacturers in case of delivery problems comparison of different plastics materials for a single production task market analyses, e.g. a search for manufacturers producing PA 6 with a content of 30% carbon fibers. 

Because of reasons mentioned above the preparation, the dimensions, and the pretreatment of the test specimen have been standardized (DIN standard or ASTM standard). The important characteristic values of technical polymers are listed in databases (Campus, Polymat).
