Study of basic properties of NR latex
Hevea latex is originally composed of spherical particles. Some of these particles become attached to each other to form groups or chains. Table 2 demonstrates that the particle size of rubber particles from whole fresh NR latex is relatively smaller than that from centrifuged latex, deproteinized latex and saponified latex. The size of the small rubber particles from the serum phase is smallest as 189 nm. As expected, the NR particles obtained from centrifuged, deproteinized and saponified latex rapidly combined together due to the removal of the protein and phospholipid layers.
