The real culprits are insulators, materials that do not allow current to flow easily. Engineers avoid pairing materials that are far apart on the triboelectric series.
Common Material Pairing Examples for the Triboelectric Effect
When a rubber-soled shoe scuffs across a wool carpet, the rubber aggressively pulls electrons away from the wool. Because the plastic does not conduct electricity down to your hand, the charge remains on the comb until it finds a path to ground, often resulting in the hair standing on end or the comb attracting small pieces of paper.
If this charge is not managed with grounding systems, it can lead to sparks that ignite dust explosions. When you pull a plastic comb through your hair, the friction transfers electrons to the comb.
Triboelectric Effect: Key Material Pairings for Static Electricity
Plastic is a prime insulator that causes static electricity to build up on surfaces. Therefore, the same materials—like synthetic clothing or vinyl records—will generate much more dramatic static electricity in a dry climate compared to a humid one.

Looking at What material causes static electricity from another angle can help expand the discussion and give readers a second clear paragraph under the same section.
More perspective on What material causes static electricity can make the topic easier to follow by connecting earlier points with a few simple takeaways.
