| Résumé : |
When optimizing the performance of a styrenic block copolymer (SBC) pressure-sensitive adhesive (PSA), the focus often lies on the polymer and resin system, not on the oil that is used as a plasticizer. Since many adhesive formulations contain significant amounts of plasticizer, it can be valuable to evaluate the impact that different types of oil have on specific adhesive systems.
Mineral oil consists of a mixture of different hydrocarbon molecules with different chemical characteristics and, in addition to the molecular distribution, the oil can be more or less refined. All of these factors influence the performance of the oil in the adhesive.
Mineral oil that is used as an adhesive plasticizer originates from crude oil. Crude reserves can be found in a number of locations worldwide, and different crude sources result in different types of plasticizing oil, typically categorized as naphthenic or paraffinic. Depending on the molecular size distribution, the density of crude oil can be characterized from light (0.83 kg/dm3) to heavy (1.04 kg/dm3). |
