This study demonstrates how Finite Fiber’s Varamix® aramid fiber blends can be customized to meet your specific polymer compound property requirements. Our ability to introduce different degrees of fiber fibrillation during the proprietary blending process, enables our technical team to work with the compounder to develop a unique balance of cured compound performance properties.
Previously polymer compounders were limited to only altering the concentration of single fiber structure. With a customized Varamix® product properties can be optimized to a much greater degree.Depending on what properties are most important, we have a balanced reinforcement solution for you.
The following graphs are for an EPDM compound with a constant 12 phr loading of Varamix®. The x-axis represents the various fiber blends or the degree of fiber fibrillation. The “with grain” orientation was set on a mill at a 2 minute run time to simulate fiber orientation in the various polymer processing technologies.
Whether you need a specific cut length, custom packaging, or formulation support, our engineers are here to help you find the right Varamix® fiber for your application.
