9 Naphthenic Oil Refining at Nynas 40 C: cst Sulphur < 15 ppm 0.9% Aromatics: 0 12 % 9 Nynas AB, Technical Development and Market Support

10 Refining Trends Group I Group II Group III Solvent Extraction Processing VI: ~ Max. 40 C: ~1000 cst Sulphur ~1 % Severe Hydrogen Processing VI: ~ Max. 40 C: 100 cst Sulphur < 10 ppm Severe Hydrogen Processing / Wax Isomerization VI: >120 Max. 40 C: 50 cst Sulphur < 5 ppm Higher quality engine oils and fuels Group I refineries closing ~ 67% of process oils used in tyre production are based on Group I technology New capacities Group II, II+, III ~ 33% of process oils used in tyre production based on hydrotreating technology 10 Nynas AB, Technical Development and Market Support

11 Health, Safety and Environmental Legislations

12 1907/2006/EC (REACH), Annex XVII, Entry 50 Extender oils shall not be placed on the market, or used for production of tires or parts of tires if they contain: more than 1 ppm of or, more than 10 ppm of the sum of all listed PAHs 12 Nynas AB, Technical Development and Market Support

13 Commission Regulation (EU) No 1272/2013 amending 1907/2006/EC (REACH) Articles shall not be placed on the market for supply to the general public, if any of their rubber or plastic components that come into direct as well as prolonged or short-term repetitive contact with the human skin or the oral cavity, under normal or reasonably foreseeable conditions of use, contain more than 1 mg/kg (0.5 mg/kg for toys) of any of the listed PAHs. 13 Nynas AB, Technical Development and Market Support

14 Tire Labelling US Label on its way? EU Label in 2012 Japan Mandatory label in place Korea Mandatory label from Nov Brazil Draft legislation filed Regulation (EC) No 1222/ Nynas AB, Technical Development and Market Support

15 Key Performance Parameters for Tyres Rolling Resistance (Fuel Economy) Wet Grip (Road Safety) Noise Emissions Tread Wear 15 Nynas AB, Technical Development and Market Support

16 Case Study: Truck Fleet: 100 trucks and trailers 13 SEK per Liter average diesel price km annual milage 30 Liter per 100 Km fuel consumption On heavy vehicles such as trucks, the rolling resistance accounts for up to 40 percent of the energy consumed 60% on trailer axle 25% drive axle 15% steering axle 2.4 Million liters diesel eaten by the rolling resistance of the tires, corresponding to 31 MSEK 16 Nynas AB

17 Tire Labelling: How to get better ratings? Raw Materials Tyre Design & Modeling Process Equipment 17 Nynas AB, Technical Development and Market Support

18 Contribution of Chemistry Rolling Resistance Low styrene Low vinyl ESBR/CB SSBR/silica funct-ssbr/silica Wet Grip High styrene High vinyl High Tg Abrasion Low Tg High cis-br CB 18 Nynas AB

19 Rubber Test 19 Nynas AB, Technical Market Support

20 Rubber Test How do commercially available oils perform with the new types of S- SBRs? Functionalized (chain-end modified) SSBR in this test: Styrene content: 21 wt.% Vinyl content: 62.5 wt.% Mooney: 68 Tg: -25 C 20 Nynas AB

30 Tear Strength 30 Nynas AB

31 Rebound Resilience 31 Nynas AB

32 Filler Dispersion (Light Microscopy) 32 Nynas AB

33 DIN Abrasion 33 Nynas AB

34 tan δ temperature sweep 34 Nynas AB

35 DMA Wet Grip Rolling Resistance 35 Nynas AB

36 DMA 36 Nynas AB, Technical Development and Market Support

37 Fuel Economy Getting the balance right better Naphthenic Black Oil TDAE / MES RAE DAE Wet Grip better 37 Nynas AB, Technical Development and Market Support

38 Conclusions Refining Trends Low PAH legislation leads to a phase-out of DAE High-performance engine oil requirements lead to Group I oil refinery closures (affected oils: DAE, RAE, MES, TDAE) Demand for Naphthenics and Gr II, III Paraffinics will increase Tire tread compounds with Naphthenic Black Oil (Nytex 4700) show a superior performance in terms of fuel saving and hence help cutting CO 2 emissions. Today s portfolio of low-pah tire oils provides an excellent toolbox to steer the balance between rolling resistance and wet grip. 38 Nynas AB
