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 BO PET film is most often used in narrow strips that are used to wrap harnesses of insulated conductors in cables in a helix. BO PET 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 BO PET 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 BO PET electrical insulation films as insulation in electric-vehicle batteries is growing significantly.
In addition to transparent films, BO PET electrical insulation films dyed in the mass are being used increasingly in this sector.
