Friction sensitivity is an approximation of the amount of
friction
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding (motion), sliding against each other. There are several types of friction:
*Dry friction is a force that opposes the relative la ...
or rubbing a compound can withstand before prematurely exploding. For instance,
nitroglycerin
Nitroglycerin (NG), (alternative spelling of nitroglycerine) also known as trinitroglycerin (TNG), nitro, glyceryl trinitrate (GTN), or 1,2,3-trinitroxypropane, is a dense, colorless, oily, explosive liquid most commonly produced by nitrating g ...
has an extremely high sensitivity to friction, meaning that very little rubbing against it could set off a violent explosion. There is no exact determining the amount of friction required to set off a compound, but is rather approximated by the amount of force applied and the amount of time before the compound explodes.
