InstaHot generates the heat energy through the exothermic chemical reaction of metal powder and oxides in the presence of water. The chemicals go through multiple levels of processing to arrive to desired formulation. Once processed the proprietary chemicals are packed in a heater pouch. The material for the heater pouch is designed to be water permeable. The packed chemicals upon coming in contact with water initiate an exothermic reaction. This exothermic reaction is the heat source for InstaHot.It also design keeping in mind of safety of the food packet. The surface temperature of the InstaHot heater pouch does not go beyond 95℃ to ensures the safety of the food packet.


  • InstaHot provides a temperature rise of 45℃ for a 300gm pouch under standard conditions
  • InstaHot has been tested under different climate conditions
  • Tested as per RoHS 2011/65/EU for heavy metals and EU/10/2011 for chemical migration analysis
