Product: Reduced Iron sand powder
Color: Black
Usage: Heat pack
Packing: 25 kg/bag or ton bag
Reduced iron powder for heat package
Description
When air enters, the reduced iron powder can immediately react with oxygen to generate heat, which can keep the temperature at about 45 degrees for up to 4 hours.
