The Eastman Plastolyn Olefin Resin series offers a range of high-performance thermoplastic resins engineered for demanding industrial applications. Derived from purified aromatic monomers, these hydrocarbon resins combine water-white clarity with tailored softening points, enabling compatibility across diverse polymers such as PVC, ABS, and polyolefins.
Their advanced molecular design ensures superior thermal stability and UV resistance, outperforming conventional C9 resins in color retention and durability under prolonged environmental exposure
Optimized for polymer modification, the series enhances melt flow, adhesion, and mechanical properties in adhesives, coatings, and sealants while maintaining low VOC content for eco-sensitive applications.
Hydrogenated Structure – Fully hydrogenated design for superior weather, UV, and chemical resistance.
Color Stability – Water-white appearance with no yellowing, ideal for transparent or light-colored formulations.
Thermal Performance – High softening point ensures stability in high-temperature processing and applications.
Eco-Friendly & Low VOC – Complies with food-contact, hygiene, and environmental safety standards.
Broad Compatibility – Seamless integration with polyolefins, elastomers, PVC, and ABS for flexible formulation.
Adhesives & Sealants – Hot-melt adhesives (HMAs), pressure-sensitive adhesives (PSAs) for labels, tapes, and hygiene products.
Coatings & Inks – Weather-resistant industrial coatings, automotive refinish, and overprint varnishes.
Polymer Modification – Enhances flow, tack, and mechanical properties of PVC, ABS, and elastomers.
Packaging & Rubber – Food-grade packaging adhesives, film laminates, and tire compounding for improved aging resistance.

Q1: What is the primary function of Eastman Olefin Resin Plastolyn in PVC formulations?
A: Eastman Olefin Resin Plastolyn functions primarily as a processing aid and rheology modifier in flexible and rigid PVC compounds. It enhances melt strength, improves surface finish, and supports uniform dispersion of fillers and pigments during extrusion or calendering.
Q2: Is Eastman Olefin Resin Plastolyn compatible with common plasticizers used in PVC?
A: Yes, it demonstrates broad compatibility with major PVC plasticizers—including phthalates, adipates, and citrates—and does not adversely affect plasticizer retention or migration behavior under typical processing and service conditions.
Q3: How is Eastman Olefin Resin Plastolyn typically incorporated into PVC compound formulations?
A: It is generally added during the dry-blend stage prior to high-shear mixing or introduced directly into the extruder feed throat. Dosage depends on formulation requirements but typically ranges from 0.1% to 2% by weight of the total compound.
Q4: Does Eastman Olefin Resin Plastolyn impact the thermal stability of PVC compounds?
A: Eastman Olefin Resin Plastolyn is thermally stable under standard PVC processing temperatures and does not interfere with conventional thermal stabilizer systems. It does not generate acidic degradation products that could accelerate PVC dehydrochlorination.
