Development of Methodology for Production of Biodegradable Cushion from Tapioca Starch
Main Article Content
บทคัดย่อ
The research report covered the development of methodology to compound a plastic resin suitable for making a loose-fill foam product and the processing method for producing loose-fill foam. The first part of the research reported the processing method for transform tapioca starch into thermoplastic starch and a compounding method for producing a compound resin that was designed for processing into the loose-fill foam. The compound resins were thermoformed into dumbbell shape samples which then were subjected to mechanical strength testing and determination of a melt flow index. In the latter part of the research, the extrusion technique for producign a loose-fill foam product was described. Development included a foaming method with a chemical blowing agent by using a single screw extruder. The loose-fill foam samples were investigated for density, expansion ratio, and compression strength. This research also showed a success of using the developed compound resin, which contained tapioca starch, to produce the loose-fill foam product.
