What is the difference between EPR (Ethylene Propylene Rubber) and Chloroprene (Neoprene)?

These materials serve different roles in rubber cable construction:

EPR (Insulation): Known for superior dielectric strength and high-temperature stability (up to 90°C). It is often used as the primary insulation for the cores.

Chloroprene/Neoprene (Sheath): Used for the outer jacket. It provides the “toughness”—protecting the cable against tearing, oil ingress, and flame spread.
