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
The standard package for Eastotac™ C series resins is a 25-kilogram (55.1-pound) multiwall paper bag. Samples (1 kilogram) are available for evaluation.

Storage

Due to the thermoplastic behavior, pastillated and half-ball 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. 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.

When stored in accordance with the MSDS, in it''s original unopened container in an enclosed area and protected from moisture, extreme temperatures and contamination, this product (in solid form only) is estimated to continue to meet applicable sales specifications for more than 2 years from the date of manufacture. First in first out inventory control is recommended.
