Red Phosphorus
You strike a match on the rough strip on the side of the matchbox.
The rougher side of a matchbox is typically made of a material called red phosphorus. Red phosphorus is a chemical compound that is abrasive and can ignite when rubbed against a rough surface, such as the striking strip on the side of a matchbox. This ignition creates the necessary friction to light the match when struck against the rough surface.
SCIENCE! Two factors enable the match to ignite: rubbing causes friction which causes heat, and the side of the matchbox also contains a catalyst which aids combustion.
