  1. High performance TPE in Automotive?

  2. Trends in Automotive Technology • Yesteryears “You can have any colour as long as it is black”

  3. Trends in Automotive Technology • Today

  5. Facts and Figures • Over 2 millions tonnes of Plastics in Europe alone. • The most widely specified material. • More than 1000 plastics parts. • On average, 100kg of plastics replaces 200-300Kg of conventional materials. E.g. 4.2Kg lighter in Engine cover and 5Kg in Fuel tanks. • Cuts oil consumption by 12 million tonnes and reduce CO2 emissions by30 millions tonnes/p.a. just in Western Europe.

  6. Trends in Automotive Technology • The future

  7. Trends in Automotive Technology • Reduce exhaust emissions. • Better fuel economy. • Improved safety. • Increase comfort and convenience. • Reduce weight Vs functionality. • Reduce COST!!!!

  8. Trends in Automotive Technology European Union Directive 2000/53/EC “End of Life Vehicle” 8 to 9 million tonnes of waste every year. • Design and Manufacture for Re-use, Re-cycle and Re-covery. • Reduction and Control of Hazardous substances.

  9. Trends in Automotive Technology Noticeable shift from: • Thermosets to Thermoplastics. • Amorphous to Crystalline polymers. • Moderate to High temperature materials. • Approx. 25% increase in volume of Plastics.

  17. DuPont™ ETPV engineering thermoplastic vulcanizates Description: a high performance cross-linked elastomer dispersed in: a high performance thermoplastic elastomer Recycling code (ISO 11469): > AEM + TPC - ET < AEM = ethylene acrylic elastomer TPC - ET = thermoplastic ether ester elastomer Finally introducing…….

  18. The cross-linked elastomer brings: • Heat resistance • Low hardness • Creep- and compression set resistance The thermoplastic elastomer brings: • Excellent oil and grease resistance • Excellent flexural resistance • Allows usage on standard thermoplastic processing equipment The combination of these materials brings: • Significant cost savings versus cross-linked rubber • Excellent oil and heat resistance • Recyclability DuPont™ ETPV is a thermoplastic elastomer in the shore A range that resists >150oC in air for 3.000 hours (retains >50% of elongation at break & tensile strength) in combination with good oil resistance.
