Chlorinated Polyethylene Cable Applications – Ensuring Reliability in Wire and Cable Systems
Chlorinated polyethylene (CPE) has established itself as a premier material for wire and cable applications, offering an exceptional combination of mechanical strength, aging resistance, flame retardance, and electrical insulation properties. From heavy-duty jacketing to thermoset primary insulation, CPE plays a critical role in ensuring the reliability and safety of electrical systems across industries.
Understanding CPE in Cable Applications
CPE is used in wire and cable applications as a jacketing compound and as a primary insulation material. The high initial mechanical properties and excellent aging characteristics of CPE warrant its consideration as a synthetic elastomer for heavy-duty jacketing for a wide variety of constructions. The polymer modifier's ability to impart flame retardance and improve flexibility while maintaining other important performance characteristics has caused its use in developing new thermoset primary insulation systems.
