Apex® Flexible PVC: Compounds for Wire & Cable Applications

Not all PVC compounds are created equal—especially when it comes to the demanding requirements of wire and cable applications. Cable manufacturers need materials that balance flexibility, electrical performance, flame retardance, and long-term stability across a wide range of operating conditions. Apex® Flexible PVC compounds are engineered specifically for these challenges, offering consistent processing, dependable insulation performance, and formulation options that support flame-retardant requirements where needed.

Designed for both insulation and jacketing applications, Apex® PVC delivers reliable mechanical properties and durability over the service life of the cable. Backed by Teknor Apex’s deep expertise in wire and cable compounding, Apex® solutions help manufacturers meet performance expectations while supporting compliance with applicable safety and regulatory standards.

Apex® Flexible PVC compounds are engineered to meet the safety and electrical performance requirements of wire and cable applications, with flame-retardant options available to support applicable fire safety standards. These materials provide stable dielectric properties and consistent insulation performance, helping maintain electrical reliability over the life of the cable. Low-smoke and reduced-emission formulations are also available where needed to help limit smoke and corrosive byproducts during fire events.

Apex® Flexible PVC compounds are developed to support compliance with global wire and cable standards, with many formulations available with UL recognition and designed to meet RoHS and REACH requirements. Teknor Apex also offers low-smoke, reduced-toxicity PVC options, along with recycled-content and bio-based variants for select applications. These materials are produced within ISO-certified manufacturing systems, helping ensure consistent quality, traceability, and reliability for global cable markets.

Fire performance is a critical consideration in wire and cable design, particularly in enclosed or occupied environments. Apex® Flexible PVC compounds can be formulated to deliver flame-retardant performance with controlled smoke generation, helping cable manufacturers meet application-specific fire and safety requirements. While PVC is a halogen-containing material, low-smoke Apex® formulations are available to balance flame performance, electrical reliability, and compliance needs where halogen-free materials are not required.

Wire and cable systems are exposed to ongoing mechanical stress from bending, routing, vibration, and installation handling, along with sustained operating temperatures typical of electrical environments. Apex® Flexible PVC compounds are engineered to maintain flexibility, insulation integrity, and mechanical strength under these conditions, helping cables perform reliably over their service life. By improving durability and reducing the need for premature replacement, these materials also support sustainability goals through longer lifespan and more efficient use of resources.

The Apex® Flexible PVC Performance Series includes multiple compound families engineered to meet the diverse requirements of wire and cable applications, from insulation and jacketing to specialty performance needs. Each series is designed to deliver a specific balance of properties such as flexibility, flame retardancy, oil resistance, and electrical performance. This product selector helps engineers and buyers narrow down the most suitable Apex® PVC compounds based on cable type, application environment, and required performance characteristics.
