What materials are used to seal cables from moisture and moderate physical damage?

The use of plastic and rubber to seal cables against moisture and moderate physical damage is a widely accepted practice in electrical and telecommunications applications. Plastic materials, such as PVC or polyethylene, provide a protective outer layer that is resistant to water penetration and environmental degradation. This is essential for ensuring the longevity and reliability of cable installations, especially in outdoor or damp conditions.

Rubber materials, on the other hand, are often used to create gaskets or seals that enhance the water-tightness of cable assemblies. Rubber’s flexibility allows it to conform to various shapes and maintain a tight seal even if the cable experiences slight movement or deformation. Together, plastic and rubber effectively create a robust barrier against moisture and physical impacts, making them suitable for protecting cables in various environments, from residential settings to industrial applications.
