Summary

Institute of the Plastics and Paints Industry (IPTiF) and Plastics Works „Wąbrzeźno-Erg” have commenced the manufacture of a carrier film from plasticized PVC for selfadhesive electroinsulating tapes, based exclusively on domestic raw materials. During the stage of formulating the composition of the carrier film, the effect of both monomeric and polymeric plasticizers on the properties of plasticized compounds (above all the strength and dielectric parameters and migration of plasticizers) has been investigated. The suitability of the polymeric plasticizer, poly(ethylene adipophthalate) modified with isooctanol and glycerol (AFG1-Z), as developed by the Technical University in Wrocław, has been demonstrated in the manufacture of the carrier film from plasticized PVC. By introduction of this carrier film into commercial production considerable savings in convertible currency expenses have been reached due to reduction of the import of such film.
