C4 is made of an explosive called RDX with a coating of plastic over it. Think of it as an explosive in a block of plastic as a container.

C4 is basically the explosive called RDX coated in a plastic binder. The role of the plastic binder is to both coat and protect the RDX, and also make the explosive malleable.

Think of C4 as just an explosive in a plastic container.

C4 is an explosive compound known as RDX that is coated with a plastic binder. The plastic basically serves as both an protector for the explosive, and as an malleable feature for it.

Since the explosive has a coating of plastic over it, to set off C4, a blasting cap or wire is usually inserted into the explosive, and a jolt of electricity sent through it to set the RDX off.
