Natural Rubber, which is obtained predominantly from the rubber tree, Hevea Brasiliensis, is an aqueous colloid of rubber containing 30-40% rubber, by mass.
Getting the rubber in a dry form is a specialized process in itself. The raw is concentrated, i.e., its % rubber content is increased and proportion of non-rubber constituents is reduced by processes such as centrifuging and creaming.
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.
