CAMPUS (acronym for Computer Aided Material Preselection by Uniform Standards) is a multilingual database for the properties of plastics. It is considered worldwide as a leader in regard to the level of standardization and therefore, ease of comparison, of plastics properties.
Polytrimethylene terephthalate (PTT), is a polyester synthesized and patented in 1941. [1] [2] It is produced by a method called condensation polymerization or transesterification.
The development of plastics has evolved from the use of naturally plastic materials (e.g., gums and shellac) to the use of the chemical modification of those materials (e.g., natural rubber, cellulose, collagen, and milk proteins), and finally to completely synthetic plastics (e.g., bakelite, epoxy, and PVC).

With the emergence of the Internet, the capability of MDBs increased. Web-enabled MDBs provide a more centralized management and conservation of Materials data. Finding and accessing the required data is faster than to search for them in a traditional manner, e.g. from handbooks or Microsoft Excel files.
The International Material Data System (IMDS) is a global data repository that contains information on materials used by the automotive industry. Several leading auto manufacturers use the IMDS to maintain data for various reporting requirements.
Let the playoffs commence. A first-of-its-kind College Football Playoff officially kicks off Friday at 8 p.m. ET with No. 9 Indiana taking the three-hour-plus drive north US-31 to Notre Dame ...
Bioplastics are plastic materials produced from renewable biomass sources. Historically , bioplastics made from natural materials like shellac or cellulose had been the first plastics. Since the end of the 19th century they have been increasingly superseded by fossil-fuel plastics derived from petroleum or natural gas ( fossilized biomass is ...
