Latex natural rubber (NR):Â Also called Latex Polyisoprene Natural Rubber is exuded from the rubber plant, mainly from Hevea Brasiliensis (Eurbiaceae family) by tapping.There are two different stages in the structuring of Latex NR:
 Dispersing stage: Polyisoprene rubber particles are synthesized with the help of enzymes. Polyisoprene has a high harmonisation structure. Rangeing from cis-tran isomerism, high volume of homogenous molecules and high bonding level.
Serum stage: Latex becomes serum which consists of diverse contents including water (52% â 70%), protein (2% â 3%), fatty acid and derivatives (1% â 2%), glucid and heterosid (around 1%), minerals (0.3% â 0.7%).
Application: at present, centrifugal rubber is widely used in engineerings and in daily life. Because the rubber itself is a liquid containing dispersed rubber grains, which is convenient for shaping products such as mattress, gloves, mats,....
