Lightning can strike rubber although it is not a good conductor of electricity.
Thyrite is a material obtained by a special type of clay mixed with carborundum (Silicon Carbide). Thyrite is used widely in lightning arresters. Thyrite is a non-linear resistor. i.e. it has high resistance at low voltages and low resistance at high voltages. A two times increase in voltage causes the current to increase by nearly 12 times. Hence, heavy currents can be discharged during voltage strikes and other surges.
