Is obtained from the tree Hevea brasiliensis or caoutchouc tree. Natural rubber is a milky fluid latex which exudes when the trunk of the tree is cut, (tapped) and coagulates on exposure to the air. When it dried, the latex is treated with sulphur at high temperatures in a process known as vulcanization to increase the desirable properties of the final product; It has long shelf storage life, including elasticity, strength and stability.
The "Standard Ammonia Concentrate" (HA), is the most common grade of latex used and is processed using centrifuge methods; After its compounding has wide applications in manufacture of finished products like medical gloves, industrial gloves, rubber thread, balloons, condoms; It is also used as an adhesive in different types of industrial applications because It contain 60 percent of certificate dry rubber.
The low ammonia latex concentrate (LATZ) It is processed by the centrifuge system which is preserved with low quantity ammonia, and with other preservatives. The ammonia content of (LATZ) is not exceeding 0.29%; has several advantages which include better quality and lower cost of production; also can replace (HA) Latex in all normal latex applications, with a little adjustment in compounding.
Is a modern marketable form of natural rubber and was developed to compete with synthetic alternatives; Is used for making tyres, tubes, rubber mats, for upholstery and packing, Conveyor Belts, shoe Foot Wear and various other rubber products. Is a general purpose Rubber graded by precise technical standards and not by visual characteristics; Some standards may vary marginally based on the origin country.
The grades between "RSS 1" and "RSS 3", are mainly used for manufacture of for medical products, pharmaceutical and engineering. The lower grades of "RSS 4" and "RSS5" are generally used for the manufacture of automobile tyres, re-treading materials and all other general products.
