3M™ Dynamar™ High Performance Rubber Additive RA 5300 is designed for use at low loadings to improve the processing in extrusion and molding operations. As a rubber processing additive, RA 5300 can help improve the surface finish of FKM extrusions, deliver a higher yield and improve downstream processing.
Outperforming Conventional FKM Additives
3M™ Dynamar™ High Performance Rubber Additive RA 5300 exhibits exceptional stability for compression set and heat age resistance compared to conventional fluoroelastomer (FKM) additives, and at loadings less than 1 PHR it has little to no effect on rheological properties. Dynamar high performance rubber additive RA 5300 may also aid molding processes with improved flow, release, and tool fouling, especially at higher molding temperatures (approximately 400°F).
Traditional techniques for mixing FKM compounds can be used to incorporate Dynamar RA 5300. The same properties that allow this product to perform in extrusion and molding processes can also be seen in the mixing process. Sticking to two-roll mills and internal mixers can be lessened with the use of RA 5300.
Delivering Custom Solutions
3M offers over 50 grades of fluoroelastomers with varying monomer composition, Mooney viscosity and fluorine content. This broad offering, combined with our expertise in application and product development, translates into greater design flexibility.
For decades, we have been able to supply unique solutions to meet the increasing market challenges in developing and producing state-of-the-art fluoroelastomer products at the highest quality level.
