3 Dawn Polymer TPV Market Main Products: more than 80% TPV for Auto application (Sealing System, interior and exterior, safeties, dust cover, etc.); Market Ranking: Ranked second for three consecutive years in domestic market, only after AES; Development Plan: Install a new product line has capacity 5,000MT/Y in Oct 2011, and install another product line(5,000mt/y) in Mar We have signed the contract of buy equipments, our capacity will be 25,000MT/Y. TPV Field Ranking: TPV Capacity will be No.3 in the world (Exxon 500,000MT/Y, DSM 60,000MT/Y), and No.1 in China.

4 Dawn Polymer TPV Dawnprene Marketing Share High-quality,100% owned technology in China The only TPV manufacturer in china who can compete with AES,DSM China marketing share 50% within 5~10 years 2011 the first china TPV plant which will list on the stock market.

5 Dawn Polymer TPV Key Competitors Dawnprene 14% market share in China AES 74% Dawn 14% Nantex 2% DSM 10% DSM AES Dawn Nantex

6 Dawn Polymer TPV Strategy 2012,20,000 capacity unit on process start produce TPU new unit running achieve 10,000 tons capacity annual sales 8000~10000tons, revenue $100~120 million 2008 biggest producer, Second supplier compare with AES second processing unit purchasing

7 Application 1. Auto sealing system

8 TPV for Auto Seals TPV for Auto Sealing System Application

9 The quality problems of EPDM and PVC type Auto seals Un-tight Seal, easy leaking Corner joint part easy breakage Ageing deformation, color changes, cracks Seal and body clamping force attenuation, a serious contraction in the use of the product. PVC seals length size change a lot, a serious contraction in the use of the product. EPDM seals after long time use will appear white at the surface Flocking seals flock easy off, and a large friction resistance with glass

10 TPV can well solve some seals quality problems Compression resistance- compared to other elastomers, TPV even at high temperatures can maintain a higher percentage of the original shape. Fatigue resistance- for door and power sealing application, TPV at -60 ~100 under a million times through the flex will not break. Good processability, can meet the sealing component s most strict requirements of compression set and dimensional tolerances. High weatherability- TPV s stability of UV, ozone (mechanical properties and color change) is much better than other elastomers. Good appearance, TPV parts is aesthetic, non-sticky, non-brittle, there is a friendly and comfortable feeling. Super sealing performance, with time and temperature, the sealing force change is small, and the elastic recovery is high. ----That is why the global car sealing system love use TPV

11 Advantage of production design As TPV thermoplastic processing characteristics, which allow designers more flexibility in design, especially the complex structure sealing product. Advantage of cost stable TPV price relatively stable: 2010~2011 first half year, the EPDM price rose nearly 100%, the same period TPV price increased lower than 20%.

12 Example 1) Water cutting seals Hard plastic body Soft rubber body Wear resistance layer PP or high hardness TPV Wear-resistance, low frictional factor TPV Low hardness TPV

13 Example 2) Glass run channel Auto window frame glass

14 Glass run channel produce technology Traditional technology Raw material: EPDM EPDM EPDM Extrusion Micro wave curing PU Spray PU Spray adhesive flocking Mould pressing vulcanize Injection bond EPDM Mould pressing Injection bond vulcanize NYLON FIBER EPDM

15 Glass run channel produce technology Extrusion Micro wave curing Spray adhesives On line flocking Injection & mould press curing corner joint

16 TPV glass run channel Wear-resistance TPV coating Low hardness TPV Wear-resistance, low frictional factor TPV Composite Extrusion Injection bonding TPV TPV

17 Example 3) Door seals TPV+Water (or EPDM) Foams Low hardness TPV TPV Color TPV or Natural TPV+ colored resin Composite Extrusion Low hardness TPV Metal framework Aluminium Strip l Product and leftover materials can be totally recycled. l Simple Process, easy molding, no need vulcanize, equipment cost is low. l Better weatherability, chemical resistance, fatigue resistance and longer service life than EPDM.

18 Example 4) Encapsulated quarter light l Good sealing properties l Scarp and leftover material can be recycled l Simple Process, high efficiency, low process cost l Tightness, nice appearance. l Weatherability Better than EPDM

19 Example 5) Windshield seals Composite Extrusion Low hardness TPV Section A Section B High hardness TPV or PP Injection bonding

20 Example 6) Roof line seal

21 Application 2. Dust cover, Air intake hose

22 Application 2: dust cover, air intake hose

23 Dust cover, air intake hose TPV(55A) 7.90 TPV(64A) 7.10 TPV(73A) 3.00 CR EPDM CSM Processing equipment and easy process NR Flexural life / Million times

24 Dawnprene TPV Applications

25 shock absorbing dust cover

26 3D blowing Advanced technology: soft shore A and hard shore D elastomers were joint very good, no need use fastener A 11-40D

27 Steering column cover 11-73A 11-67A

28 Application 3: Safeties application

29 Application 3: safeties TPV has good insulating property, volume resistivity ~10 16 Ω cm, dielectric strength more than 18kV/mm. FR, Anti Hi temperature, Anti high voltage TPV Auto Ignition wire Anti voltage 35KV FR V-0 Anti temperature 170 super process ability

30 Application 3: safeties Auto ABRS cover

31 Auto ABRS cover Two materials for ABRS cover: Japan car use TPV(TPO) TPV hardness 90A~95A(42D) Euro and American Car use TPEE Germany car use 55D TPEE American Car use 45-50D TPEE

32 Application 4: interior and exterior application

33 Application 4: interior and exterior Interior surface, wheel cover, fairing air flap, rearview mirror liner, light seal, fuel oil inlet cover, mudguard, wiper top cover, hand brake handle cover, steering wheel cover, etc.

35 Example: Non skeleton windscreen wiper TPV Non skeleton windscreen wiper: take the most advanced windscreen wiper design no pivot windscreen wiper, take the newest material technology, use memory metal as the main structure, one piece design, there is no joint pivot. The wiper will better fit the radian of windshield after long time use, to avoid wiper noise.

36 Example: hand brake grip Good hand feeling

37 Interior surface

38 Interior surface Molding technology: Extrusion calender, cavity block or male mold blister. Bond EPP to replace expanded PU, whole recycable. TPV interior surface strength: Good anti high and low temperature, light resistance, low weight, good hand feeling, very low content of VOC.

39 TPO(TPV) Interior surface specification: (soft) Unit 11-72MP 11-82MP MFR(230 5KG) g/10min 3 4 Density Kg/m Hardness Shore A Shore A Tensile Strength Mpa break % % Strain Mpa
