Processability is a rather loosely defined term in the rubber industry. For the synthetic rubber producer it generally involves the mixing characteristics during pigment incorporation into the rubber. Mixing cycle times are often fixed. Therefore, variations in the consistency of the synthetic rubber can result in poor or dirty mixes or mixes that require abnormally long times to complete. Laboratory testing for the variations leading to inconsistent mixing has not been entirely satisfactory. The standard ASTM Mooney test is important but does not give a complete picture. The delta Mooney test (15 minute reading less the 1.5 minute reading) is often used and specified for ...
