Plastic database

The use of computers in design and related fields is widespread and will continue to expand. It is increasingly important for designers to keep up to date continually with the nature and prospects of new computer hardware and software technologies. For example, plastic databases, accessible through computers, provide product designers with property data and information on materials and... 

CAMPUS, the plastics database CAMPUS is an internationally known database software for plastic materials, developed by close cooperation with leading plastics producing companies. It is available worldwide from leading material suppliers. More than 50 plastics producers are participants of CAMPUS. Information about the latest list of participants and distribution addresses can be found at the CAMPUS homepage http //www.CAMPUSplastics.com/. This web site also includes extensive information about the data content of CAMPUS and links to the participants web sites. It is important to emphasize that only CAMPUS participants distribute CAMPUS diskettes. Each plastic producer distributes his own diskette to his customers without charge. 

The CAMPUS Plastics Database, covering some 40 manufacturers grades of materials, provides data to a standard format in accordance with ISO 10350 [11] and ISO 11403 [12]. It is available from participating manufacturers and through www.campusplastics.com. Singlepoint properties listed include creep modulus after 1 h and 1,000 h and thermal expansion. Multi-point data listed include creep modulus at five temperatures. The CAMPUS website provides addresses and telephone numbers from which data to the agreed format may be obtained, and links to some manufacturers websites directly.

In practice, the complete viscosity functions are often not specified for polymer melts. Instead, the melt flow rate (MFR) and/or the melt volumetric rate (MVR) is used. These parameters specify how much polymer mass and/or volume will flow out of a normalized flow channel within a specific period (e. g [cm3/10 min]) when subjected to stress (see DIN EN ISO 113, ASTM D1238). Low-viscosity, easily flowing polymers have high MFR or MVI values, while high viscosity/slow flowing polymers have low MFR or MVI values. These values are listed e.g. in plastics databases such as CAMPUS [3],...

Plasticizers are the most voluminous additives of semi-rigid and flexible PVC formulations. Their properties, mechanisms of action, and effect on properties of plasticized materials have been extensively discussed in a specialized monographic source, and data on different grades are included in the plasticizer database. ... 

The above table shows that a large number of products manufactured from PVC require plasticizers. The table also shows that there is a large variety of plasticizers (the Plasticizers Database contains 1475 plasticizers). The data ranges of properties included at the end of Table 3.1 show that there is a variety of choices to fulfil requirements, but the section Potential adverse effects also shows that not very well thought-out plasticizer selection may affect the properties of the end product.

Finally, the plastics database CAMPUS should be mentioned here. About forty plastics manufacturers have joined forces to compile a database for their customers. This provides information on the most important physical-chemical parameters and processing properties of all plastic materials on the market and in particular of the HDPE resins according to a unified scheme. The website www.campusplastics.com provides information on the database and access to the various data sets of the companies involved. 

The listings are published annually by UL in their Recognized Component Directory in section QMFZ 2 and/or QMFZ 8 and on the Internet, respectively. An excerpt for individual plastic grades is available on the yellow cards (Plastics Recognition Yellow Cards, Figure 2.31) that can be ordered at any time from UL or downloaded from the Web (www.ul.com). The homepage (www.ul.com/plastics) allows the search for companies that offer UL-certifled products. There is also a plastics database, which can be accessed after registration.
