LATEX CONCENTRATE (HA)
TYPE
Natural rubber latex concentrate (HA) is a high ammonia centrifuged concentrated latex of the sap of Hevea brasiliensis trees. This general purpose type latex finds its application in a variety of products.
APPLICATION
HA latex is the most widely used form of concentrate and has the advantage that the only preservative (ammonia) it contains is volatile. Hence it may be used confidently in food applications and for medical goods.
HA latex concentrate has wide applications especially in the dipped products like medical or industrial gloves, balloons, condoms, catheters, finger cots, tubing, etc.
It is also used as an adhesive for footballs, bandages, in wood lamination and for binding different types of materials.
It gives excellent films of high clarity and has good adhesion characteristic.
STORAGE
Store the product under shelter at temperatures between 10�°C and
35�°C
Creaming of latex may occure during storage. It is therefore necessary to stir well the latex before used.
As the product is based on natural rubber latex changes in colloidal properties may occur on storage.

HANDLING PRECAUTION
Before handling, read product information, chemical safety data sheets and container label for safe use, physical and health hazard information.
PACKING
Available in both bulk and drum.
We serve the export of rubber latex lumb in large quantities according to your needs, and we are also looking for investors for rubber plantation that we manage (with profit sharing system, the core pattern and plasma, the ratio 50%: 10%: 40%, 50% for investors, 10% of us / managers, 40% owner of the land / people / our members).
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.
Rubber Cup Lumps 60% - 65% DRC, using Dry Oven method. Available for regular supply, with 2000 MT ready for dispatch at special rates. Terms of Payment Advance/L/C. Product Certification provided by - SGS CI AFL Laboratory. Option for Inspection of Material at site is available.
