radiation processing of natural rubber latex for indonesia
Radiation processing of natural rubber latex
The technology is called radiation vulcaniza- tion of natural rubber latex, or RVNRL. It uses high-energy gamma radiation (it also can use electron beams) to initiate vulcanization, a process that chemically bonds molecules to produce rubber elasticity and strength.

Investigation of Radiation Vulcanization of Natural Rubber
The radiation dose for better cross-linking of natural rubber latex with six parts per hundred rubber (phr) n-BA was 15 kGy absorbed dose according to the research. The results also show that addition of 0.3 parts per hundred rubber (phr) urea to the latex before irradiation caused the crosslinking density and tensile strength increase respectively.

Natural Rubber / Latex – Production of Natural Rubber
Processing of Natu ral Rubber. Then a final rolling is performed using a textured roller and the resultant rubber sheet is dried. Following this, the rubber is ready for export of further processing. This type of natural rubber accounts for about 90% of natural rubber production. Figure 3. Final rolling of the latex sheets using a textured roller.
