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 Kg 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 CO 2 emissions by 30 millions tonnes/p.a. just in Western Europe.

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