Tempra’s Self-heating Technology is based around the reaction between Glycerol and a Potassium Salt, but with a significant difference.
Tempra are able to tailor the heat generation to:
– control the rate at which the reaction  occurs
– introduce a lag before the reaction initiates
– control the ultimate temperature reached by the product
In this way Tempra’s Scientists and Engineers can design and formulate a safe, effective heater for every type of application.
Tempra’s Self Heating Cup uses this technology to give the safest, most effective cup in the market.
