Centrifuged Latex 60% Of Dry Rubber Content (Cenex)
Centrifuged latex is a white liquid with classification of HA and LA. Processing of natural rubber latex into high quality latex concentrate of 60% dry rubber content is done through centrifugation. Centrifuging involves the separation of preserved field latex into two fractions, one containing the concentrated latex of more than 60% dry rubber and the other containing 4-6% dry rubber. Centrifuged latex is today available commercially in two different verities with high ammonia (min.0.6% of ammonia) and low ammonia (max. 0.3% of ammonia). The former is preserved solely with ammonia and later contains one or more preservatives besides ammonia. LA latex has several advantages which include better quality, lower cost of production by way of savings in preservatives, acid and low cost of effluent treatment.
Grades and applications
High Ammonia (HA) -Foam products, dipped goods, adhesives, elastic thread, household and industrial gloves, balloons, rubber bands and finger caps.
Low Ammonia (LATZ) - Preferred for all applications when de ammonia is necessary for product manufacture. Requirement for centrifuged natural rubber latex is given in the table.
