17 17 PP Nanocomposites Effect of Polybond ® 3200

18 18 Polybond Applications Wood-Plastics Composites WPC

19 19 Market Definition Natural Fiber Filled Plastics Readily available, low cost natural fibers are used at high filler loadings ( %) in thermoplastics Natural Fibers –Wood Flour –Wood Fiber –Agricultural Fibers/Flours Hemp, Flax, Kenaf, Rice Hulls, Nut Shells Thermoplastics –Polypropylene –Polyethylene –PVC

20 20 Applications Building & Construction Decking & Docks Railing Systems Interior Trim Automotive & Transportation Interior & Trunk Parts Engine & Transmission Covers

21 21 Polybond Function: Help disperse the wood fiber in the Polyolefin Cause wood fiber to adhere to the Resin

22 22 40% Wood-filled HDPE Effect of PB 3009 Level on Flexural Properties

23 23 New Coupling Agents Polybond 3029 commercialized for Polyethylene

24 24 Characterization Data 190 o C, 2.16KgMA by Titration Polybond % Polybond % Physical forms of PB 3029 Pellets Micropellets (granules)

25 25 Formulation: 60% wood-HDPE

26 26 Formulation: 60% wood-HDPE

27 27 Building the Bridge btw Non-polar & Polar Resins

28 28

29 29 Polybond Compatibilizers Improves the PP/Nylon blend properties –Strengths –Stiffness –Toughness

30 30 NYLON/PP BLENDS Tensile Strength

31 31 NYLON/PP BLENDS Flexural Strength

32 32 NYLON/PP BLENDS Notched Izod Impact

33 33 NYLON/PP BLENDS Reverse Notch Izod Impact

34 34 Polybond Coupling Agents in non Halogenated Flame Retardant PO Compounds (PE, PP, TPOs)  Application Area  Wire & Cable Compounds  Electrical &Electronic  Flame Retardant Fillers  ATH (aluminium trihydrate)  Magnesium Hydroxide - Mg(OH) 2  Inorganic Fillers  Talc, CaCO3, Silica, Kaolin… Polybond addition improves Tensile strength Notched Izod impact Long term heat ageing Moisture sensitivity

35 35 Polybond 3009 and 3039 in 62% ATH Filled HDPE Tensile Property PB3039 produces best balance of properties

36 36 Polybond 3009 and 3039 in 62% ATH Filled HDPE Flexural Modulus PB3039 produces best balance of properties

37 37 Aged for 7 in water Polybond 3009 and 3039 in 62% ATH Filled HDPE Tensile Properties- Hydrolytic stability Unaged

38 38 Aged for 7 C in air Polybond 3009 and 3039 in 62% ATH Filled HDPE Tensile Properties- Heat ageing Unaged

39 39 Notched Izod Impact Strength of 60% ATH Filled LLDPE POLYBOND 3029 in FR PE compound LLDPE = Escorene LL5252 – 52 MFI
