    • The compatibilty of TPU and NR blends 

      Nor Azwin, Ahad; Sahrim, Haji Ahmad; Norazwani, Muhammad Zain (Trans Tech Publications, 2014-01)
      The blends of thermoplastic polyurethane (TPU) with natural rubber (NR) at four different blends ratios were prepared via melt blending, with addition of liquid natural rubber (LNR) as compatibilizer. The effect of blend ...

    • Drop weight impact analysis of laminated polyurethane foam/cloisite 30B clay 

      Firuz, Zainuddin; Hazizan, Md Akil; Sahrim, Hj Ahmad, Prof. Dr.; Rozaidi, Rasid; Syed Nuzul Fadzli, Syed Adam (Trans Tech Publications, 2014-01)
      Laminated polyurethane foam composite was produced by incorporating Cloisite 30B clay as filler and aluminium sheet as the skin. Initially, PU foams were synthesized with reaction of natural oil polyol and isocyanate with ...

    • Effect of carbon nanotubes on the compression test and energy absorption of aluminium/polyurethane-carbon nanotubes foam sandwich 

      Sinar Arzuria, Adnan; Siti Nursyafiqah, Samsudin; Firuz, Zainuddin; Nur Azni, Azizan; Hazizan, Md Akil; Sahrim, Hj Ahmad, Prof. Dr. (Trans Tech Publications, 2014)
      The foam was prepared by mixing the polyols, isocyanate and carbonnanotubes (CNTs) at 1000 rpm speed. The different content of the CNTs are varies from 0 3 (0, 0.5, 1.5, 2.0, 2.5, 3.0) percent by weight. The foam sandwich ...

    • Effects of NR and liquid NR loading on swelling behaviour of TPU/NR blends 

      Nor Azwin, Ahad; Sahrim, Hj Ahmad, Prof. Dr.; Norazwani, Muhammad Zain (Trans Tech Publications, 2013)
      The blends of thermoplastic polyurethane (TPU) with natural rubber (NR) at four different blend ratios were prepared via melt blending at 180°C and 190°C, with addition of liquid natural rubber (LNR) as compatibilizer. The ...

    • Flexural analysis of polyurethane foam and sandwich composite foam via experimental and finite element Cmethods 

      Firuz, Zainuddin, Dr.; Sahrim, Haji Ahmad; Rozaidi, Rasid; Syed Nuzul Fadzli, Syed Adam (Trans Tech Publications Inc., 2013-09)
      Polyurethane (PU)/montmorillonite (MMT) composite foam were synthesized with reaction of diisocyanate with polyester polyol by a batch process. In this research, water was used as the blowing agent with TEGOSTAB B8407 and ...
