Compatibility and Solubility
Compatible at all ratios, or in limited but practically useful proportions, with natural and synthetic rubbers, butyl rubber, SBR, SBS (styrene-butadiene-styrene) block copolymers, SEBS (styrene- ethylene/butylene- styrene) block copolymers, SIS (styrene-isoprene-styrene) block copolymers, and EVA (ethylene-vinyl acetate) and EBA (ethylene-butyl-acrylate) copolymers. Soluble at all useful proportions in aliphatic, aromatic, and chlorinated hydrocarbons. Insoluble in alcohols and water.
Packaging
Regalite™ S5100 hydrocarbon resin is pastillated and packed in polyethylene bags of 20 kg net, and supplied on shrinkwrapped pallets of 50 bags (1000 kg) each, from Eastman facilities in the Netherlands and from warehouses located in Europe. Regalite S5100 is supplied in heated, insulated and inerted bulk containers, from Eastman facilities in the Netherlands.
Storage
Due to the thermoplastic behavior, pastillated and flaked resins may fuse, block or lump. This can be accelerated under any of the following conditions: 1) above ambient temperature 2) prolonged storage 3) pressure, e.g., stacking pallets, or a combination of these conditions. This is particularly applicable for low softening point resin grades.
In order to maintain the flake or pastille shape, we therefore recommend storing the material in a temperature-controlled area, be careful with stacking material or applying pressure and preventing prolonged storage.
It should be noted that lumping does not have a negative impact on the product specifications. Due to the nature of the product, claims regarding lumping cannot be accepted.
For the molten material a storage temperature of 160°C under inert conditions is recommended.
Resins are prone to gradual oxidation, some more so than others. This could result in darkening and/or it could have an adverse effect on the solubility of the resin in organic solvents or on its compatibility with polymers. Accordingly, it is recommended that strict control of inventory be observed at all times, taking care that the oldest material is used first.
Regalite™ S5100 hydrocarbon resin will remain within product sales specification limits for a period of at least twelve months after shipment from Eastman production facilities in the Netherlands, provided storage conditions outlined in this data sheet are observed. However, as we can neither anticipate the conditions under which the resin is processed nor the end use applications for which it is used, the product should be reanalyzed for critical properties at the end of its shelf life to determine if it meets specification for use.
