Rubber & Plastic Modification

Eastman products for plastic modification include hydrocarbon resins and modified polyolefins. Hydrocarbon resins modify rubber and plastic by affecting the hardness, flexibility, coefficient of friction, and bondability of the compound. Modified polyolefins function as coupling and alloying agents in plastic compounds, greatly improving the incorporation of fillers and permitting the mixing of otherwise incompatible polymers such as polypropylene and nylon. In fiberglass composites modified polyolefins increase the adhesion of the plastic to the glass, resulting in improved tensile strength.

Product Group	Brand Name	Benefits	Compare
Functionalized Polyolefins	Eastman G™	Functionalization introduces reactive sites and wetting properties to polyolefins. In filled plastic composites this allows better wetting, reduced viscosity, higher tensile strength, better impact resistance and permits higher filler levels. In polymer alloys they allow the mixing of normally incompatible materials such as polypropylene and nylon.
Hydrogenated Hydrocarbon Resin	Eastotac™	Fully hydrogenated grades have good compatibility with polyolefin plastics, natural rubber, butyl rubber, EPDM, SIS / SEBS block copolymers, polyisoprene and amorphous polyolefins. Partially hydrogenated grades are compatible with SBR, SBS, polybutadiene, and EVA. Wide range of softening points. Low color, good thermal stability, excellent UV resistance.
Hydrogenated Hydrocarbon Resin	Regalite™
Hydrogenated Pure Monomer Resin	Regalrez™	Best available resistance to UV light, thermal and color stability. Very low color. Fully hydrogenated grades have good compatibility with polyolefin plastics, natural rubber, butyl rubber, EPDM, SIS / SEBS block copolymers, polyisoprene and amorphous polyolefins. Partially hydrogenated grades are compatible with SBR, SBS, polybutadiene, and EVA.
Pure Monomer Resins	Endex™	Low color aromatic resins compatible with SBR, EVA, PVC, ABS and acrylics. Wide range of softening points from liquid to 160°C. The major function of these products in rubber and plastic processing is to improve flow characteristics at processing temperatures while not detracting from cohesion or tensile strength at use temperature. In styrenic block copolymers these products modify only the styrene phase. The product families differ in composition, color, softening point, melt viscosity and glass transition temperature.

Rosin Resin	Foral™	Fully hydrogenated rosin and rosin esters with low color and good stability. Good compatibility with a wide range of polymers including polyolefins, EVA, SBR, styrenic block copolymers, acrylics, and ethylene-methacrylic acid ionomers. Useful as a flow modifier and softener as well as improving bondability of low surface energy compounds.
Rosin Resin	Foralyn™	Partially low color hydrogenated rosin esters with good color and heat stability. Broad compatibility and softening points from liquid to 100°C. Useful as a flow modifier, plasticizer and softener as well as improving bondability of low surface energy compounds.
