Education:

  • B. Sc. (Rubber Industry Management) Prince of Songkla University, Thailand
  • Ph. D. (Rubber Technology) Prince of Songkla University, Thailand

Research interests:

1) Rubber composites

2) Alternative chemicals for rubber

3) Thermoplastic elastomer

Natural rubber (NR), a green polymer and major economic crop of Thailand, is widely used in various applications. My research focuses on improving the performance of NR composites through the incorporation of fillers, particularly alternative fillers derived from renewable resources and industrial wastes. These fillers aim to enhance curing behavior, mechanical properties, and overall composite performance while reducing energy consumption and material costs. 

I am interested in the development and application of alternative fillers, activators, and chemical additives for rubber compounds. My recent work involves the use of fly ash from power plants as an alternative filler and activator, which has been shown to enhance cure characteristics and mechanical properties of NR vulcanizates. Ongoing research extends to other industrial wastes and by-products, such as rice husk ash, oil palm ash, and plastic waste, to reduce or replace conventional commercial chemicals in rubber formulations.

My research also includes thermoplastic elastomers, with an emphasis on sustainable material design. This involves the use of alternative matrices and recycled or waste-derived materials to develop environmentally friendly polymer composites with improved processing and functional properties.
