The main components of the friction match tip are potassium chlorate and phosphorus trisulfide. Slightly rubbing on a rough surface generates enough heat to cause a chemical reaction between these two substances and ignite.

The manufacturing of match powder heads is the same as that of wooden stick matches, which are processed into a common match continuous machine and dipped with medicine to make matches. But there is no need to apply wax before applying the medicine. The adhesion between the wax stem and the medicine head is poor. Before applying the medicine slurry, pre-treatment is required to remove the wax layer on the surface of the stem end (where the medicine is applied) and slightly loosen the paper layer to increase the adhesion between the medicine head and the stem; The drying of the medicine head is carried out at a lower temperature (20-40 ℃) to avoid the melting of paraffin in the stem.
