THE INFLUENCE OF RECIPE FORMULATION AND ELECTRIC FIELD FREQUENCY UPON DIELECTRIC LOSS IN PLASTIFIED PVC FILMS
Plastified polyvinyl chloride (PVC) films are largely used in the clothing and footwear industries. The composition of the PVC-based blend and the curing stage determine the main characteristics of the final films.

| description | Plastified polyvinyl chloride (PVC) films are largely used in the clothing and footwear industries. The composition of the PVC-based blend and the curing stage determine the main characteristics of the final films. Lately, radio frequency fields (RF fields) have gained popularity as heat generators in different processing stages of polymer films, like the PVC ones. The dielectric behaviour of PVC films can be controlled by the recipe formulation of plastisol blends. This paper presents the influence of the chemical nature and concentration of some auxiliaries, added in the plastisol blend, upon dielectric loss, tg in plastified PVC films obtained in high frequency electric field. The chemicals used as additives in the recipe formulation were: polydimethylsiloxane (PDMS) polymethylhydrosiloxane (PHDMS), nonylphenol ethoxylate emulsifier NF10 (NE) and collagen hydrolizate (CH). Additives concentration was in the range 4-6 parts. The RF field was provided by a high capacitive generator with 380 V supply voltage, and 13.56 MHz working frequency. Increased concentration of auxiliaries determined the increase of tg irrespective the nature of the chemical auxiliary. The dielectric loss of PVC films, due to the presence of chemical additives, increased in the following order: PDMS< NE< CH< PHDMS. The dielectric loss angle increased in the RF field up to a maximum value that corresponds to a critical frequency. The addition of additives to the plastisol PVC blend, as mono, binary, ternary or quaternary mixture, has a beneficial effect upon the dielectric behaviour of final films, making them suitable for use in the footwear manufacturing. |
