Technical Details & Test Data

Compatibility and Solubility

Soluble in aliphatic, aromatic, and chlorinated hydrocarbon solvents. Insoluble in alcohols and water. Compatible in useful proportions with natural and synthetic rubbers, ethylene-vinyl acetate (EVA) copolymers, amorphous polyolefins, paraffin and microcrystalline waxes, ethylene-vinyl acetate (EVA) resins; styrene-butadiene rubber (SBR) copolymer, styrene-ethylene-butylene-styrene (SEBS), styrene-isoprene-styrene (SIS) and styrene-butadiene-styrene (SBS) block copolymers.

Packaging & Availability

Packaging Information

The standard package for Eastotac™ H series resins is a 50-pound (22.7-kg) multiwall paper bag. Samples (1 kilogram) are available for evaluation. Eastotac™ Resin H-100R is also available for molten shipping.

Storage & Handling


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.
