Centrifuged Latex (Cenex)

NATURAL RUBBER LATEX 60% DRC (HIGH AMMONIA)

NATURAL RUBBER LATEX 60% DRC (LOW AMMONIA)

Field latex is a white or slightly yellowish opaque liquid with a specific gravity, which varies between 0.974 and 0.986. It is a weak lyophilic colloidal system of spherical or pear shaped rubber globules suspended in an acquiesces serum. Field latex is centrifuged to manufacture latex concentrated of 60% rubber content. Centrifuged latex is commercially available in two different varieties, one with high ammonia (above 0.60%) and the other with Low Ammonia (less than 0.30%). It also contains secondary preservatives like TMTD (0.0125%) and zinc oxide (0.0125%). Grading, packing, and making of centrifuged latex are as per specifications prescribed in IS 5430.,In India, High Ammonia (HA) latex concentrate with a 60% Dry Rubber Content (DRC) is primarily sourced from rubber plantations and processed mainly in Kerala, the country's largest rubber-producing state. This concentrated latex is used across a wide array of industrial applications, from dipped goods to adhesives.

HA latex concentrate (60% DRC) is produced by separating natural rubber from field latex via centrifugation. The high concentration of ammonia (<0.6%image.gif ) acts as a preservative, preventing coagulation and maintaining the latex's stability and fluidity for a longer duration.

Applications of high ammonia (HA) latex

Due to its high stability, excellent elasticity, and film-forming characteristics, HA latex (60% DRC) is used in a variety of industries.

Sr. No	Grade	Areas of Consumption
1	High Ammonia (HA)	Foam products, Dipped Goods, Adhesives, Elastic Thread, House hold Industrial Gloves, Balloons, Rubber Bands and Finger Caps
2	Low Ammonia (LATZ)	Preferred for All Applications where De-ammoniation is necessary for product manufacturing
3	Single and Double Centrifuged latex.	High technology dipped products such as Condom, Examination Gloves, Surgical, Gloves, Catheters, etc.
