Films for electrical and insulation purposes


The use of plastics for the production of cables is mainly affected by the modernization of electrical and telecommunications networks. Power cables account for almost 70% of the consumption of plastics used for cable production and sheathing. There are also telecommunications applications, cables for the automotive industry, mining and specialized industries such as the aerospace industry.

Our BOPET film is most often used in narrow strips that are used to wrap harnesses of insulated conductors in cables in a helix. BOPET films increase insulation against electric shock, but in particular they prevent the cable harness and the outer sheath of the cable from sticking/welding when sheathing the cable. The film is also used as a BOPET laminate with a mica foil. This laminate is used as flame-retardant insulation for cable harnesses.

With the current development of e-mobility, the potential of using BOPET electrical insulation films as insulation in electric-vehicle batteries is growing significantly.

In addition to transparent films, BOPET electrical insulation films dyed in the mass are being used increasingly in this sector.
