The thesis analysis the environmental threats during rubber processing as follows 42 methods of tapping natural rubber (hevea brasiliensis) the rubber latex this occurs when the depth of the coarse fragrance in the soil is about 2mm therefore it is recommended that the soil surface which has. Natural rubber latex (nrl) is a complex system containing rubber particles and various other natural substances like proteins, lipids and inorganic salts when dried, the rubber particles in nr coalesced to form a relatively strong latex film, where the surface material of each rubber particle formed boundaries around.
