ASTM D 3346 - 12 Standard Test Methods for Rubber Property - Processability of Emulsion SBR (Styrene- Butadiene Rubber) With the Mooney Viscometer (Delta Mooney)

Current edition approved May 1, 2012. Published June 2012. Originally approved in 1974. Last previous edition approved in 2007 as D3346 – 07. — 4 p.
These test methods explain the use of the shearing disk viscometer to obtain an indication of the processability ofnon-pigmented emulsion styrene- butadiene rubbers (SBR). They may also be used to separate those polymers that are easy to process from those that are difficult to process within a group of polymers of the same type.
