Polyamid also known as Nylon ( trade name given by DuPont ) finds it's use in cable production industry as isolation material.  First Polyamid was discovered 1931. First mass production begun  in 1938 in USA. It was   PA 6,6 at first.  Later in 1940'S PA 6 was developed in Germany.  Polyamid today comes in different grades such as PA6-PA6,6-PA6,12-  PA4,6-PA12-PA11 etc.  Polyamid comes in different forms. Granules for extrusion.
Polyamid is used in coaxial and communication cables because of its' high dielectric constant.  Polyamide also has high level of chemical resistance. This is the reason polyamid is preferred as jacketing material in such environments.  PA is highly flammable.
