Tracking Resistance — A Key Material Property
The tracking resistance of the housing material determines how well it resists the formation of conductive carbonized paths under electrical stress and contamination. Silicone rubber has inherently better tracking resistance than EPDM or epoxy, but formulation variations significantly affect performance. IEC 60587 testing provides quantitative comparison between materials.
