4. Introducing 3MTM DynamarTM RA 5300 High Performance Rubber Additive
Unique 3M chemistry
Based on experimental results described in this presentation, RA 5300 offers both processing and performance improvements
Improvements were seen in extrusion and injection molding with minimal affect on performance properties

5. Introducing 3MTM DynamarTM RA 5300

6. Equipment / Experiment Set-up

9. Experiments and Results MDR Cure and Scorch Comparison Results

10. Experiments and Results MH and Mooney Viscosity Results

11. Experiments and Results Physical Property Comparison

12. Experiments and Results Compression Set Comparison

13. Experiments and Results Heat Aging Property Loss Comparison

14. Experiments and Results Shear Stress Comparison at 100°C
RA 5300 was comparable to the Carnauba Wax
At rates of approximately 1000/s, all of the compounds have similar flow properties

15. Experiments and Results Shear Stress Comparison at 150°C
At shear rates below 500/s RA 5300 exhibits better flow
At and above 500/s, the Carnauba Wax containing compound results in a considerably lower stress

16. Experiments and Results Garvey Die Extrusion Comparison

17. Experiments and Results Mold Release Comparison
Samples molded in the half round spiral tool all released from the groove easily and allowed for relatively simple part removal
All of the samples, except those produced using the RA 5300, stuck in the grooves of the deeper, more submerged sample, pulling the part away from the nozzle tip and having to be pried out of the mold with a wooden tool
Parts molded using the RA 5300 released totally from the groove

19. Experiments and Results Thermal Stability

20. Summary
Based on these results, 3M™ Dynamar™ RA 5300 could offer both processing and performance improvements in comparison to other FKM processing aids
Sharper edges and smoother surfaces were achieved in Garvey Die extrusions
Improved mold release and fouling in injection molding
Incremental processing improvements can be achieved with increased loadings of the RA 5300, with 0.5 and 1.0 PHR being the optimal loading range
Minimal affect on rheological and performance properties
Thermally stable up to 280°C
