rubber insulation

Electrical cord sheath

Rubber insulation is a protective covering made from natural or synthetic rubber, used to shield electrical wires and cables from contact, moisture, and heat.

The material's flexibility and resistance to electrical current make it standard in wiring: The old rubber insulation had cracked and needed replacing.

Rubber insulation also appears in thermal applications, preventing heat transfer in pipes and equipment.
