They are excellent electrical insulators and, unlike their carbon analogues, are non-flammable.

PCN have been used mainly for their chemical stability, including low flammability, their (electrically) insulating properties and recalcitrance, including resistance to biodegradation and biocidal function.
7 March – Iranian nanotechnologists created a modern sort of electrical insulator with elevated dielectric constant, this achievement is used in electronics, optoelectronics and electrochemical factories.
In addition to holding the brain together, they provide electrical insulation for the neurons, fight off infection, and join together to form a protective blood-brain barrier.

PCBs (polychlorinated biphenyls), in widespread use since the 1930’s, are a family of over 200 oily compounds used in lubricants, plastics, electrical insulation, pesticides, dishwashing liquids, and other products.
Because of law restricting acceptable manual handling weights, Europe has seen a move towards lighter weight composite manhole cover materials, which also have the benefits of greater slip resistance and electrical insulating properties.

If a failure of electrical insulation occurs, all bonded metal objects in the room will have substantially the same electrical potential, so that an occupant of the room cannot touch two objects with significantly different potentials.

There are concerns that communal centres, which are not supported by the Government or local authorities, are overcrowded and lack access to clean water, electricity, insulation, sanitation and waste management facilities, increasing the risk of disease outbreaks.
The United Nations Headquarters buildings were built when the use of asbestos-containing materials was common for thermal insulation of piping and ductwork, for fireproofing/acoustic treatment of walls and ceilings, for strengthening vinyl floor tiles and for electrical insulation.

But did you know that it is also used in making rubber and plastics, textiles and paints, pencils and wallpaper, electrical insulators and drainpipes, insecticides and fertilizers, and it is often found even in medical preparations that you buy from the pharmacist?
PCN have been used mainly for their chemical stability, including low flammability, their (electrically) insulating properties and recalcitrance, including resistance to biodegradation and biocidal function; they share these properties and their scope of application with PCB, by which they were gradually replaced after World War II.
CNs have been used mainly for their chemical inertness, including low flammability, their (electrically) insulating properties and recalcitrance including resistance to biodegradation and biocidal function; they share these properties and their scope of application with the PCBs, which they were gradually replaced by after WW II (cf.
