Technical Data Sheet
Regalite™ UltraPure 5100 Hydrocarbon Resin


Applications
  • Hygiene adhesives
  • Solvent borne packaging adhesives
  • Waterborne hygiene adhesives
Key Attributes
  • Excellent heat stability
  • Improved resistance to oxidation
  • Low odor
  • Low organic volatile content
  • Low trace chemicals
  • Water-white initial color

Product Description
Regalite™ UltraPure 5100 hydrocarbon resin is a unique partially hydrogenated water-white thermoplastic resin with low targeted volatiles after aging, low odor, and low, stable amount of substances of interest as a function of aging temperature. Regalite UltraPure 5100 hydrocarbon resin has improved color stability compared to the heritage grade with the same aromatic content and softening point. Like Regalite S5100 hydrocarbon resin, this resin is an excellent tackifier in hot melt adhesives based on SIS and SBS block copolymers, where it provides superior room temperature cohesion combined with very low adhesive viscosity.

Compatibility and Solubility
Regalite™ UltraPure 5100 hydrocarbon resin is a partially hydrogenated, light colored resin which has been formulated to give a novel balance of hot melt viscosity and cohesion. The specific balance of molecular weight and polarity of Regalite UltraPure 5100 hydrocarbon resin enables the formulation of SIS and SBS based hot melt adhesives with very low viscosity and long open time, with superior room temperature cohesion compared to fully hydrogenated resins. Regalite UltraPure 5100 hydrocarbon resin has a very good resistance to thermal and oxidative degradation and low odor. The high polarity of Regalite UltraPure 5100 hydrocarbon resin, combined with the inherent low adhesive viscosity, result in excellent adhesion to low surface energy substrates such as polyethylene.

Soluble at all useful proportions in aliphatic, aromatic, and chlorinated hydrocarbons. Insoluble in alcohols and water.

Compatible at all ratios, or in limited but practically useful proportions, with SBS (styrene-butadiene-styrene) block copolymers, SIS (styrene-isoprene-styrene) block copolymers, SBR (styrene butadiene rubber), EVA (ethylene-vinyl acetate) and EBA (ethylene-butyl-acrylate) copolymers.

Packaging
Regalite™ UltraPure 5100 hydrocarbon resin is pastillated, packed in polyethylene bags of 20 kg net, and supplied on shrink-wrapped pallets of 50 bags (1000 kg) each, from Eastman’s facilities in the Netherlands and from warehouses located in Europe.

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 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.

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™ UltraPure 5100 hydrocarbon resin material will remain within product specification limits, as mentioned in the sales specification sheet, for a period of at least twelve months after shipment from Eastman''s 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, we recommend that the material be tested upon receipt.
