The company claims Buna Nd 22 EZ and Buna Nd 24 EZ offer the following advantages:
• High molar mass through narrow polydispersity;
• Low Mooney viscosity;
• Long chain branching to accelerate incorporation of fillers into the rubber matrix; and
• Chemical modification of chains to enhance rubber/filler interaction.
