Product Description
Plastolyn™ 290 hydrocarbon resin is a versatile, aromatic, water white, very high softening point resin for use in polymer modification, adhesives, overprint lacquers, coatings and a variety of other applications. Recommended as a flow modifier in such polymers as polyvinylchloride (PVC), acrylonitrile-butadiene-styrene (ABS) and block copolymers. Its water white color and good economy, combined with superior heat and ultraviolet light (UV) stability compared with conventional C9 hydrocarbon resins, provide formulators a new level of quality without sacrificing competitiveness.

Compatibility and Solubility
Soluble in aromatic and chlorinated hydrocarbons, ketones and ethers. Insoluble in aliphatic hydrocarbons, alcohols and glycols.

Packaging
Pastilles, in multiwall paper bags (50 lbs, 22. 7 kg net wt).

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.

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.
