Electrical Wire Insulation and Cable Jacketing

Selection of the best electrical insulators for your specific application will depend on several factors including material resistance to the required voltage, flexibility, look and feel, life cycle/duration, and environmental factors to which it will be exposed (extreme heat or cold).

Mercury Wire currently leverages the benefits of thermoplastics in the insulation and jacketing of the wire and cable it manufactures. To learn more about the general use and characteristics of each thermoplastic compound, please click on any of the links below.

Polyvinyl Chloride (PVC)

Polyvinyl Chloride is one of the most widely produced synthetic plastic polymers. PVC is generally available in both rigid and flexible forms. The rigid form of PVC (sometimes referred to as RPVC) is used in the manufacturing of pipes for plumbing, doors, and windows used in the construction industry, and even commercially in the manufacturing of credit cards, bottles and certain packaging.

Polyethylene (PE)

Polyethylene (PE) is primarily used in the packaging industry in the manufacturing of plastic milk and water jugs, detergent and shampoo bottles, and some plastic bags. As a wire and cable insulator and jacketing material, polyethylene is mixed with additives to make it softer and more flexible. Continue Reading . . .

Polypropylene (PP)

Polypropylene (PP) is in many aspects similar to polyethylene in both physical and electrical characteristics, but with improved thermal properties. Polypropylene is reasonably economical and can also be foamed to improve its electrical properties. Continue Reading . . .

Polyurethane (PUR)

Polyurethanes (PUR) are highly desirable polymers for their ruggedness, durability, and flexibility, but also for their ability to be foamed. PUR provides stability and long life, superior dielectric properties, and are resistant to high temperatures and moisture.  Polyurethanes are used in manufacturing a broad range of products across multiple applications including marine, automotive, military, industrial and communications.

Chlorinated Polyethylene (CPE)

Because of its resistance to oil, heat, flame, and its durability against the elements, chlorinated polyethylene (CPE) is typically used to insulate wire and control cables for industrial power plant applications, appliance wire, lead wire, coil leads, transformer leads, and motor lead wire.

Nylon

Nylon refers to a group of plastics known as polyamides. Nylon is extremely flexible and serves as tough insulation –  exhibiting strong abrasion, cut-through, and chemical resistance. Nylon can be extruded over softer insulation compounds to provide an extra layer of protection against moisture, increase impact resistance, and protect against high wear. Continue Reading . . .
