The universe of wires and cables isn't confined to only a couple of regular wires, for instance, copper wires, and so on. The progressive changes in the past some decades have provided them with strong varieties that include:
Silver-plated copper electrical wire
PTFE insulated silver-plated copper wire, and
Silver-coated copper wire, etc.
Teflon wires are the most important part of the universe of wires and cables that are considered to be special for their amazing properties. Polytetrafluoroethylene (PTFE) is a solid, durable, waxy, and non-flammable resin produced through the polymerization of tetrafluoroethylene. The basic brand names for PTFE are Teflon, Fluon, Hostaflon and Polyflon. The same PTFE coating is done on the wires and cables using a sophisticated PTFE coating line to make them sturdy and durable.
PTFE is hydrophobic and remains 100% safe against all types of synthetics, erosion, as well as the oxidation process, and has an amazingly low coefficient of the grating. PTFE is also widely utilized as a nonstick coating in a wide range of cookware and a large number of other development applications apart from wires and cables.

Some major applications of PTFE coated wires and cables
PTFE coated wires manufactured on the ultra-modern PTFE coating line supported by the capstans are used in a wide range of critical fields. There are various characteristics like electrical obstruction, temperature, dampness, and synthetics that make them a great material wherever different types of tools, products, as well as components need to be extremely reliable even in the most demanding applications.
PTFE-covered wires give wonderful scope and assurance when clinical components require a smooth and durable covering. PTFE’s non-chipping properties completely settle on the covering of the wire offering the best of advantages. The wires and cables used in the medical field need to be very safe and reliable because they are used in very critical areas. This is the reason PTFE-covered wires are considered to be the most suitable ones for such critical applications.
Established in the year 1974, Supermac Industries (India) Limited is one of the leading manufacturers and suppliers of capstans and PTFE coating line. Today, the company is meeting the demands of industries operating in the wires and cables sector including power, optical fiber, house wiring control cables, and medical lines. Some other products in the portfolio of the company include extrusion machines, crossheads, caterpillars, capstans, screws and barrels, take-ups, and pay-offs. On the infrastructural front, the company is well-equipped to meet the challenges of the ever-changing requirements of the extrusion machine industry, both in India and abroad.
