The objective of this work was to investigate the relationship between different factors characterizing the network structure on the tackiness of silicone rubberud(PDMS). A custom tack testing device was constructed, based on the existing Tel-Tak principle. The experimental work involved testing the tack of silicone rubber in relation to crosslink density and type of contact, the development of tack with time of contact in relation to the molecular weight of the polymer, and the influence of loose, uncrosslinked polymer chains embedded in theudcrosslinked network.
