Abstract
eng: On the basis of a feasibility study of the plasticiser substances and
groups of substances that are commercially available on the market
today, nine substances were selected for further investigations. PVC compounds plasticised
with these selected substances were prepared and tested for a number of properties that
were considered as primary selection criteria for medical applications. Compounding was
easy with all the investigated plasticising substances and it was easy to prepare
specimens and test samples by injection moulding with all the prepared compounds. An
attempt was made to rank the selected and investigated substances in comparison with a
reference DEHP plasticised PVC compound. Some have a slightly lower strength value, some
have a slightly lower strain at break value, and some have a higher cold flexibility
temperature. None of the substances was rejected as potential alternatives to DEHP.
However, much more data are needed before DEHP can be seriously substituted in medical
devices.
Resumé
dan: På basis af studier af de blødgørende stoffer og stofgrupper, der er kommercielt
tilgængelige i dag, er der udvalgt og undersøgt ni stoffer. Der blevet fremstillet
PVC-kompounder med hvert af disse stoffer som blødgøringsmiddel. Disse kompounder er
blevet prøvet for en række udvalgte egenskaber, som anses for at være primære
udvælgelseskriterier for anvendelse i medicinsk udstyr. Alle kompounderne var lette at
fremstille, og det var uden særlige problemer at forarbejde alle kompounderne ved sprøjtestøbning.
Det er blevet forsøgt at rangere de undersøgte blødgørende stoffer i sammenligning med
en DEHP-blødgjort PVC-kompound. Nogle har lidt mindre styrke, nogle lidt mindre
brudtøjning (relativ brudforlængelse), og nogle har en højere cold
flexibility-temperatur. Ingen af
stofferne er blevet forkastet som potentielle alternativer til DEHP. Imidlertid kræves
der mange flere data, før man kan erstatte DEHP i medicinsk udstyr.
