A proprietary blend of non-toxic chemicals inside a non-woven fabric pad, sealed with ultrasonic sealing technology and individually wrapped in foil, contained inside a 280 x 180mm multilayered constructed bag with 95mm gusset including a high heat resistant open zipper, a steam vent and instructions.
APPROXIMATE TOTAL FRH WEIGHT: 68g including outer printed bag.
HEAT GENERATION: Following the addition of any non-flammable liquid 90/150mls, the chemical mixture will create an exothermic reaction that will generate heat and steam to raise the internal temperature to up to 220 °F with a duration of 10-15 minutes depending on altitude and temperature.
SHELF LIFE: Minimum three years from production date. Upper limit not known if bag remains sealed.
ADVANTAGES: Stand alone, odorless, safe to use in confined and close spaces, non-flammable, based on the amount of hydrogen released, magnesium free, volatile organic compound (VOC) emissions tested and passed against California Proposition 65 criteria. Occupational exposure limits and government ad agency guidelines for cancer and non-cancer risk.
