3M™ Dynamar™ High Performance Rubber Additive RA 5300, 2 lb Box

3M™ Dynamar™ High Performance Rubber Additive RA 5300 is designed for use at low loadings to improve the processing in extrusion and moulding 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.

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. It may also aid molding processes with improved flow, release, and tool fouling, especially at higher moulding temperatures (approximately 400°F).
