Elevast™ Polymer Additives

Elevast™ polymer additives are specialty hydrocarbon fluids for technical applications that require a wide range of service temperatures and improved mechanical properties.

Designed to enhance the performance and processability of a broad range of polymer systems and applications, Elevast polymer modifiers enable fine-tuning of performance and introduce new options for intermaterial substitution.

Elevast polymer modifiers offer formulators the ability to extend low-temperature service ranges, along with increased permanence for long-term property retention and exceptional compatibility with polyolefins. Easily incorporated into polymers, Elevast polymer modifiers feature outstanding thermal and oxidative stability, are virtually colorless and odorless, and have low specific gravity along with food contact clearance.

Key benefits


Performance advantages

Glass transition temperature (Tg) reduction

In proprietary ExxonMobil testing, Elevast demonstrates significant glass transition temperature depression. Elevast also has proved to enhance Tg-related properties, such as low-temperature performance, flexibility and toughness.

Lowers melt viscosity

Because Elevast modifiers are low MW-liquids, they can decrease the viscosity of the molten polymer, or increase its melt flow rate, as shown in this ASTM D1238 test. Potential processing advantages include faster cycle/line speed and reduced energy consumption.
