Tehispolümeerid moodustavad laia ja mitmekesise isoleermaterjalide rühma. Enamlevinud tehispolümeer (e. sünteetiline polümeer) on polüeteen (tuntud ka polüetüleeni nime all; tähis PE), mis on lineaarse struktuuriga neutraalne termoplastne polümeer. Polüeteen on mehaaniliselt tugev ja seejuures elastne materjal ning tal on head elektrilised omadused (tabel 3.3). Teda kasutatakse laialt isoleermaterjalina ning torude, kile, tarbeesemete jms valmistamiseks.
Polyethene (PE), also known as polyethylene, is by structure the simplest polymer among the olefins and, at the same time, the most widely used plastic in the world.
Polyethylene is a member of the important family of polyolefin resins. It is the most widely used plastic in the world, being made into products ranging from clear food wrap and shopping bags to detergent bottles and automobile fuel tanks.
