Effect on tensile strength of composite with reduced quantity of binder at elevated process temperature: A study on Mosquito Repellant coil (Composite) with elevated process temperature of Guar Gum (binder)

Owing to the high density, the mosquito repellant coils (composite) dry only slowly and warp during drying. The flexural load bearing capacity of the coils is low, so that breakage readily occurs during handling. To provide adequate strength against breakage excess binders (guar Gum) may cause non burner problem. Therefore present study determined an optimum solution of usage of binder in mosquito coil to get the desired tensile strength with satisfactory burning quality. Binder of 3% (w/w) at normal temperature shows the same performance in terms of mechanical properties and burn time as in 1% (w/w) but at elevated temperature. The results of this study may help to optimum use of Guar Gum which intern save the natural resources and produce a better composite product.
