Enhancing Peroxide Cured FKM with Trilene® Processing Aids
Processing aids serve as a critical element for optimizing high-performance characteristics in the production and improvement of fluoroelastomers. Lion Trilene® liquid EPDM offers compounders of peroxide-cured fluoroelastomers (FKM) distinct processing advantages that enhance production efficiency while preserving the quality of the final product.
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.
Enhanced Sheet Smoothness
Incorporating Trilene® helps achieve smoother milled sheets of TPE elastomers, which is essential for applications requiring precise surface finishes.
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.
