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.

Colorless, odorless fluid with exceptional high purity and low volatility

Improved surface appearance without sacrificing line speed

Improved compression and tension set performance

Low viscosity grades for cold temperature and high toughness; high viscosity grades for high temperature and long-term applications

Improved flow for reduced processing time and lower energy requirements

Compatible with other common additives, including stabilizers, nucleating agents, inorganic fillers, flame retardants, colorants and release agents

Performance advantages

DSC by % Elevast D50 for hPP, ICP, and RCP

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.

ASTM D1238 by % Elevast D50 by Vistmamaxx 6202, hPP, ICP, RCP, and Exact 4160.

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.

Factsheet: Elevast™ polyolefin fluid

Elevast efficiently lowers Tg of polyolefins with carefully designed liquid polymer, with minimal change in crystalline properties and without requiring exquisite morphology control.
