Thermochemistry of Combustion in Polyvinyl Alcohol + Hydroxylammonium Nitrate
Aerospace, 2021 A mixture of polyvinyl alcohol (PVA) and hydroxylammoniun nitrate (HAN) forms a gummy solid known as a plastisol, which is ionically conducting. When an electrostatic potential of 200 V DC is applied across the plastisol, it ignites.
