1 1 Energy & Advanced Materials Division 3M Specialty Additives 3M TM Dynamar TM RA 5300 High Performance Rubber Additive Productivity Performance Optimizing & Improving

2 2 Energy & Advanced Materials Division Agenda Market Status Introducing 3M Dynamar RA 5300 High Performance Rubber Additive Test methods and results Summary and Conclusions Questions

3 3 Energy & Advanced Materials Division Market Status Fluorine – Carbon Bond –Chemical and Heat Resistance Chemical resistance impacts compounding and affects processing –Polymer rich compounds –Dry, rough extrusion Additives are used to improve processing –Waxes, oils What properties are sacrificed? Is there an alternative?

4 4 Energy & Advanced Materials Division Introducing 3M TM Dynamar TM 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 5 Energy & Advanced Materials Division Introducing 3M TM Dynamar TM RA 5300

6 6 Energy & Advanced Materials Division Equipment / Experiment Set-up Common medium viscosity o-ring grade copolymer used Industry standard compound; 100 parts per hundred rubber (PHR) of the elastomer base, 30 PHR of N-990 carbon black, 6 PHR of calcium hydroxide, and 3 PHR of magnesium oxide Four compounds compared –Control –Carnauba Wax, –Struktol® WS-280, –New 3M Dynamar RA 5300

7 7 Energy & Advanced Materials Division Compounds

8 8 Energy & Advanced Materials Division Tests performed Moving Die Rheometer Viscosity Physical Properties Heat Resistance Compression Set Capillary Rheometer Garvey Die Extrusion Mini-Injection Press Loading Evaluation TGA

9 9 Energy & Advanced Materials Division Experiments and Results MDR Cure and Scorch Comparison Results

10 10 Energy & Advanced Materials Division Experiments and Results MH and Mooney Viscosity Results

11 11 Energy & Advanced Materials Division Experiments and Results Physical Property Comparison

12 12 Energy & Advanced Materials Division Experiments and Results Compression Set Comparison

13 13 Energy & Advanced Materials Division Experiments and Results Heat Aging Property Loss Comparison

14 14 Energy & Advanced Materials Division 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 15 Energy & Advanced Materials Division 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 16 Energy & Advanced Materials Division Experiments and Results Garvey Die Extrusion Comparison

17 17 Energy & Advanced Materials Division 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 ControlRA 5300

18 18 Energy & Advanced Materials Division Experiments and Results The Effect of RA 5300 Loading on Properties

19 19 Energy & Advanced Materials Division Experiments and Results Thermal Stability

20 20 Energy & Advanced Materials Division 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
