Introduction
Introduction
Elastomeric cables, popularly known as rubber cables, were originally manufactured with natural rubber insulation and sheath during the late 1970s. Over time, these have been replaced with advanced synthetic rubber materials to enhance performance and durability. Continuing its commitment to expanding the product portfolio, KDI Power began manufacturing elastomeric cables in 2003. Since then, the company has developed a comprehensive range of high-quality elastomeric cables designed for diverse industrial applications.
These speciality cables are produced using technologically advanced polymers such as EPDM, CSP, CPE, PCP, NBR, EVA, and silicone. The compounds are carefully formulated to provide halogen-free, non-toxic, heat-resistant, oil-resistant, and fire-retardant properties, ensuring reliable performance and safety in demanding environments.
KDI Power offers a wide range of specialty elastomeric cables.
