[No.1 Businesses] [ World ] Poval : 30% [world no.1] PVA film for LCDs : 80% [world no.1] EVAL resin : 70% [world no.1] Man-made leather : 25% [world no.1] HSBC(SEPS,SEBS..) : 25% [World no.2] [ Japan ] Hock and loop fastener : 65% [Japan no.1] Dental materials : 40% [Japan no.1]

    5. 5 Who is Kuraray ? [Technologies in Elastomer Div.]

    6. 6 What is all(meth)acrylic TPE ? PMMA–b-PnBA–b-PMMA = MnBM, “LA-polymer” LA-polymer pilot plant : ~500 tons/y in Japan

    7. 7 Synthesis of MnBM “LA-polymers” By our original living polymerization system Narrow MWD Mw/Mn=1.1-1.3

    10. 10 Characteristics of MnBM Novel all (meth)acrylic TPE : we have pilot plant No monomers & oligomers Low melt viscosity Elastic and soft without plasticizers Good transparency Good weather-ability, durability Good adhesion to paint Good adhesion to polar plastics (PMMA,PC,ABS…)

    11. 11 Characteristics [Flow properties] Very low melt viscosity

    12. 12 Characteristics [Dynamic mechanical properties] Elastic and soft without plasticizers

    13. 13 Characteristics [Transparency]

    14. 14 Characteristics [Weather-ability, Durability]

    15. 15 Characteristics [Paint-ability]

    16. 16 Characteristics [Adhesion to Plastics in 2K-molding]

    17. 17 Polymer Blends [Flexible MnBM + Rigid MnBM] All MnBM blends are transparent.

    18. 18 Possible applications

    19. 19 Molding Materials by LA/Plastics alloys

    20. 20 Modifiers for PLA

    21. 21 Summary Kuraray has developed novel all (meth)acrylic TPE, “LA-polymers” by own developed polymerization system. We have pilot plant for LA-polymers (~500 t/y). We can produce from flexible to rigid materials and several alloys. LA-polymers have low viscosity, good transparency, weather-ability, durability, paint-ability and adhesion to polar plastics like PMMA,PC,ABS,PVC… . Possible application fields will be Molding materials, Modifiers, PSA etc.
