1 Sustainable Fillers fr Future Elastmers Sustainably Meeting Tmrrw s Challenges Martyn Bennett Chief Scientist

2 Agenda Wh are ARTIS? Elastmers fr Tyres Sustainable Cmpunds rcb and Pyrlysis rsilica ARTIS SMG

3 ARTIS Overview Independent Materials Cnsultancy Centre f materials expertise Pint f cntact fr advice Partnerships fr Cllabrative R & D Specific cnsultancy prjects Target t establish ARTIS as the wrld leader fr the research and develpment f pyrlysis derived fillers Develping an expertise in mre general material recvery and sustainable rubber

4 Tyre usage Wrld demand fr tires is prjected t rise 4.1 percent per year t 3.0 billin units in 2019 and a value f $258b 22% Increase!! Hw are we ging t meet this need?

5 End f life ptins Dumping Shredding Landfill Engineering Fuel cement kilns Rubber pwder Devulcanisatin Pyrlysis

6 Tyre Sustainability What s in a tyre? Rubber cmpunds maybe ingredients per cmpund Steel high tensile, high value Fabrics nyln, plyester Which bits are sustainable? Mst cmpnents Plymers, fillers ils, chemicals Sustainability agendas frm tyre c s? All majr tyre cmpanies have sustainability agendas Fcus n Manufacture, use, end f life Reduced energy cnsumptin, better perfrmance, re-use Carbn Credits, sustainable materials, CO2 reductin in use

7 Sustainable materials Akutagawa Rubbercn 2014 Bridgestne are aiming fr 100% sustainable tyre, Has been achieved Mst thers will be lking at same issues and prbably als achieved it We will prduce ther 100% sustainable cmpunds

8 Sustainable materials Plymers Replacement f NR with Guayule, dandelin derived materials Butadiene surced frm Bimass Oils frm bimass and bi surced Fillers frm Bimass (carbn) Alternatives e.g rice husk silica, hydrthermal and veg derived carbn Egg and Tmat Where d they impact? Majr impacts n perfrmance Requires very specific cmpunds Gd results are achievable Recyclability?

9 Filler requirements Fillers mechanical strength Filler use in Tyres set t rise 15% by 2020 Mixture f filler types

10 ARTIS and Pyrlysis Nt new Technlgy Frequently classed pr quality Benchmarked 2014, repeat 2016 Gd quality material is available

11 ARTIS and Pyrlysis Generatin f a unique material Nt carbn black as we knw it! Frmed in-situ nt simply recvered Different surface activity Carbnaceus residue dictating: Surface Activity. Dispersibility. Bth reduce reinfrcing ptential. We understand these differences and their impact

12 ARTIS and Pyrlysis Large discrepancies in cmpsitin Very different t Std Blacks Pr market perceptin High level variability Spec required t define perfrmance rcb knwn t cntain: Originally cmpunded carbn black. Carbnaceus residues frmed during pyrlysis. Inrganic materials.

13 Weight % Cmpunding trends Increasing utilisatin f silica filler. Current, leading, passenger tyre treads cntain very little CB. Same trend emerging fr Truck and sme ther cmpnents/ applicatins % extract % SBR % carbn black % silica % zinc xide Nt a gd feedstck fr rcb prductin!

14 rsilica Prcess rsilica yields >30% achieved with careful selectin f the feedstck. N pst-reactr prcessing. Typically >95wt% silica. ~3-4wt% zinc xide (active, s shuld be beneficial). <2wt% trace elements. The nn-silica cmpnents were nt accunted fr in this study. Element Wt% Si 45.3 O 50.2 Zn 3.0 Al 1.0 S 0.5

15 In Rubber Perfrmance Slight reductin in dispersin cmpared t virgin highly dispersible Ultrasil 7000GR. Nte: N pst reactr treatment f rsilica. Best refined rcb frm crsscheck prgramme achieved Ra = 0.78µm. Nte that Ra values fr the tyre treads = 0.40 t 1.28µm. 7000GR 50:50 rsilica Ra = 0.55µm Ra = 0.65µm Ra = 0.71µm

16 In Rubber Perfrmance Impressive perfrmance cmpared t Ultrasil 7000GR cntrl. Nte that rsilica is ~95wt% silica, therefre ~5wt% nn-reinfrcing GR 50:50 rsilica 20 0 Viscsity Max-Min Hardness M300% Tensile Strength Tear Strength

17 ELASTIC MODULUS (MPa) Lss MODULUS (MPa) In Rubber Perfrmance Greater level f filler-filler interactins with the 7000GR. ΔE = E 0 -E 7000GR ΔE = :50 ΔE = 5.98 rsilica ΔE = 6.09 Reduced energy lsses with ARTIS rsilica. ~5wt% nn-reinfrcing cntent f rsilica a significant cntributr GR GR 2 50:50 rsilica DSA (%) 50: rsilica DSA (%)

18 Lg E', Pa TAN DELTA In Rubber Perfrmance Slight reductin in stiffness, as nted previusly. N statistically significant impact n T g. Wet grip perfrmance, therefre, expected t be similar GR 50:50 rsilica GR 50:50 rsilica TEMPERATURE / C TEMPERATURE / C

19 Cnclusins rcb and rsilica can ffer green alternatives t cnventinal fillers. Recycling rute dependent n feedstck cmpsitin. Predicted future grwth f tyre prductin will demand raw ingredients frm alternative surces. Ptential fr part r 100% replacement (frmulatin dependant). ARTIS currently pursuing up-scaling and ptimisatin f the rsilica prcess. 19
