POL - Abbreviation for polyethylene. Also abbreviated PE and poly. See polyethylene.
POLY - Abbreviation for polyethylene. Also abbreviated PE and pol. See polyethylene.
POLYALKALENE - A polymer, typically polyethylene, made from alkene monomer. Primary insulation compound used in MIL-W-81044.
POLYAMIDE - a) A compound characterized by more than one amide group. b) A polymeric amide (nylon).
POLYCHLOROPRENE - Chemical name for Neoprene®. Used for jacketing wire and cable that will be subject to rough usage, moisture, oil, greases, solvents, and/or chemicals. May also be used as a low voltage insulating material. Neoprene® is a trademark of the DuPont de Nemours Co.
POLYESTER - Any of a group of polymers that consists basically of repeated units of an ester and are used especially in making fibers or plastics. More specifically, polyethylene tetephthalate which is used extensively in the production of a high strength moisture resistant film used as a cable core wrap.
POLYETHYLENE - A thermoplastic material, polymerized ethylene. They are basically pure hydrocarbon resins, often with small amounts of other additives to impart needed properties. All members of the polyethylene family are excellent dielectrics. Electrically they are far superior to any other extrudable dielectric in use today. Outstanding electrical properties include high insulation resistance, high dielectric strength, low dielectric constant, low dielectric loss at all frequencies, excellent resistance to cold flow, and good abrasion resistance. One or more members of the polyethylene family also have the following properties: Resistance to sunlight, weather, chemicals, and flame. Polyethylene is widely used for insulation on telephone, signal and control cables, high frequency electronic cables, high voltage and low voltage power cables, line wire, neutral supported secondary and service drop cables. They are suitable for direct earth burial. Temperature ratings vary with type and application from 75° C up. Abbreviation PE, POL, and POLY.
POLYIMIDE - A relatively high temperature plastic developed for use as a dielectric or jacketing material, Kapton®. Usually laminated to FEP and used as heat sealable tape. It does not burn and has high abrasion resistance. Kapton® is a trademark of the DuPont de Nemours Co.
POLYMER - A material of high molecular weight formed by the chemical union on monomers.
POLYOLEFIN - A family of thermoplastics based upon the unsaturated hydrocarbons known as olefins. When combined with butylene or styrene polymers, they form compounds such as polyethylene and polypropylene.
POLYPARAPHENYLENE TEREPHTHALAMIDE - This synthetic has high tensile strength at low weight, low elongation to break, high modulus (structural rigidity), low electrical conductivity, high chemical resistance, low thermal shrinkage, high toughness (work-to-break), excellent dimensional stability, high cut resistance, flame-resistant, and self-extinguishing properties. Trade name KEVLAR ®. KEVLAR ® is a trademark of the DuPont de Nemours Co.
POLYPROPYLENE - A thermoplastic polymer of propylene with good electrical characteristics, high tensile strength, and resistance to heat.
