Enhancing Peroxide Cured FKM with Trilene® Processing Aids

Benefits of Trilene® 65 and Trilene® 77
for Fluoroelastomers

Superior Dispersion 

Trilene® acts as an excellent dispersant by enhancing the mixing process. This property ensures uniform mixing of components, which is vital for achieving consistent material characteristics. Trilene® helps to smooth out milled sheets of fluoroelastomers (FKM) and dipolymers of tetrafluoroethylene and propylene (TFE/P). When used at low levels, Trilene® 65 and Trilene® 77 have minimal effect on the physical properties of the fluoroelastomers, ensuring that performance is maintained while facilitating processing. 

Effect on Cure Rate 

The application of Trilene® 65 and Trilene® 77 does not significantly change the cure rate of TFE/P elastomer. The cure rate is consistent with that of formulations lacking these processing aids, indicating that the curing process operates efficiently and effectively. 

Improved Release Characteristics 

A significant issue associated with TFP/E and FKM is its propensity for mold fouling. Trilene® 65 and Trilene® 77 provide substantial advantages in mold and mill release, enhancing processing efficiency and minimizing downtime related to mold upkeep.




 

Minimal Impact on Physical Properties 

At low concentrations (3 phr for Trilene® 65 and 2 phr for Trilene® 77 ), these processing aids demonstrate minimal impact on the physical properties of the elastomer. This guarantees that the performance attributes, including tensile strength and elongation, are predominantly preserved, enabling manufacturers to uphold product quality. 

Integrating Trilene® 65 and Trilene® 77 as processing aids in peroxide-cured FKM formulations significantly improves processing efficiency while maintaining the superior performance attributes of the materials. By utilizing these sophisticated processing aids, manufacturers can attain enhanced product quality while effectively managing the intricacies associated with elastomer production.
