  1. The CAMPUS initiative:Grade-specific plastics selection

  2. Outline: the CAMPUS database • Data requirements for material selection • The need for standardization • The CAMPUS philosophy • The Benefits • The CAMPUS participants • Demo - CAMPUS data in CES For more information on CAMPUS, visit www.campusplastics.com Resources: • The CES CAMPUS Module in the CES EduPack) software -- Granta Design, Cambridge (www.grantadesign.com) Unit 8, Frame 8.1

  3. Data requirements for material selection • In the world today, there are over 40,000 different plastic grades to choose from. • Carrying out a selection necessitates the comparison of many different resins from many different producers. • Although data is widely available and easy to obtain, carrying out a selection can be virtually impossible. This is due to a lack of reliable, comparable data.

  4. The need for standardization Lack of Uniformity: Many national standards in use around the world: ASTM – US BS – Great Britain DIN – Germany AFNOR – France JIS - Japan Producers use different standards and report different properties and units. This prevents comparison.

  5. The need for standardisation Test standards: Test standards are not sufficiently stringent. Variability in specimen preparation, test methods and test conditions leads to non-comparable data

  6. The CAMPUS philosophy CAMPUS = Computer Aided Material Pre-selection by Uniform Standards The aim of the CAMPUS group, to achieve truly comparable data. A uniform global standard ensuring: • Uniform specimen geometry - Standardized specimen preparation - Uniform test methods - Uniform test conditions - Standard properties profile

  7. The CAMPUS philosophy ISO – The international organisation for standardization • CAMPUS adopted three ISO standards: ISO 10 350 Acquisition and Presentation of comparable Single-Point-Data e.g. Tensile Modulus, Volume Resistivity ISO 11 403–1 Acquisition and Presentation of comparable ISO 11 403–2 Multi-Point-Data e.g. Viscosity vs. Shear Rate curves • All participating producers required to produce CAMPUS data according to these standards. • Result - completely standardized test methods and uniform data format

  8. The benefits of CAMPUS • Truly comparable data for use in plastics selection • Immediate access to over 5600 grades of plastic from more than 30 suppliers • High quality data for design and CAE calculations • Eliminates need to learn each producers database and data structure • Cost savings to both end users and producers due to reduction in the amount of testing

  9. Brief history of CAMPUS 1988 Release of CAMPUS v1.0 database, single point data, jointly developed by Bayer, BASF, Hoechst (now Ticona), and Hüls (now Degussa) 1990 CAMPUS v2.0, incorporates multi-point data 1993 Dow Chemical and DuPont join CAMPUS Steering Committee 1994 CAMPUS v3.0, integration of CAMPUS ISO standards 1996 Japanese language version of CAMPUS database released 1997 49 CAMPUS participants from Europe, US and Asia 2001 CAMPUS v4.5: TPE and chemical resistance data 2007 CAMPUS v5.1: enhanced compositional data, long-term heat aging
