Effect of Starch on Mechanical, Electrical, Physical, Thermal Properties and Photo\Bio-Degradation of HIPS-Starch Blend

Author Name: Subburaj. J and Soundararajan. S | Format: Paperback | Genre : Educational & Professional | Other Details
HIPS was blended with starch in three formulations 10, 20 & 30% with compatibilizer glycerol (2wt% based on starch) using a twin screw extruder. Test specimens were prepared using an injection molding machine. Mechanical, electrical, physical and thermal properties were determined. Photo degradation using accelerated weather o meter for 25, 50, 100, 200 hrs was carried out. And then bio degradation for 45 days was carried out. The loss in mechanical properties was studied after photo degradation. After photo degradation, bio degradation was evaluated. The effect of starch on bio degradation was studied. HIPS is photo degradable and starch is bio degradable. Hence starch filled HIPS is photo & bio degradable. This photo & bio degradable starch filled HIPS is used in packaging & disposable applications like cups, lids, trays, spoons, pens & cutlery handles with lower cost.
