The latex vessels in the bark run at an angle of
3-5
0
to the right
and therefore a cut from high left to low right will open greater number of latex vessels. Hevea latex in the latex vessels of tapped trees contains 30-40 per cent rubber in the form of particles.

How do you harvest rubber from a rubber tree?
Rubber is harvested from rubber trees, which are a family of trees that belong to the family Euphorbiace; Hevea brasilienisis or Sharinga trees are the most common. Natural rubber is extracted by method called tapping,
by making incisions into the bark and collecting the fluid into vessels attached to the rubber trees
.
Why rubber tree tapping should be done carefully and with skill?
Tapping rubber tree. Each night a rubber tapper must remove a thin layer of bark along a downward half spiral on the tree trunk. If done carefully and with skill, this
tapping panel will yield latex for up to 5 years
. … The work is done at night so the latex will run longer before drying out.
Why Rubber tapping is done in the morning?
The work is done at night or in the early morning before the day’s temperature rises,
so the latex will drip longer before coagulating and sealing the cut
. Depending on the final product, additional chemicals can be added to the latex cup to preserve the latex longer.

How do you process natural rubber?
Rubber processing consists of four basic steps: (1)
mastication
, when the elastomer is sheared and the molecules are broken down to give easier flow, (2) mixing, usually carried out immediately after mastication, when additives are incorporated, (3) shaping of the viscous mass, for example, by extrusion or molding, and …
Why does the rubber tree produce latex?
The rubber tree can only thrive in hot, damp regions near the equator, so 90% of true rubber production today occurs in these areas. Within the rubber tree, latex is found. Distinct from the sap,
latex serves as a protective agent, seeping out of and sealing over wounds in the tree’s bark
.

use a whistle that mimics a local bird as they move from rubber tree to tree
. They say they use it to disguise themselves in the forest so they won’t startle the wildlife.
What is tapping in geography?
Rubber tapping is the process by which latex is collected from a rubber tree. … Rubber tapping is not damaging to the forest, as it does not require the tree to be cut down in
order
for the latex to be extracted. Jungle rubber is essentially old secondary forest, strongly resembling the primary forest.

amber rectangle on a Rubber Tree’s trunk
and, while holding the Treetap, right click that section of trunk. 1-3 pieces of rubber will then pop out of the tree.
What do the rubber tappers want?
Let Us Continue Our Sustainable Way of Life Since rubber tappers want to continue making a living from the rainforest, they need to
stop the widespread clearing of trees
. Therefore they have asked the govern- ment of Brazil to create protected reserves within the rainforest.
How does rubber affect the environment?
Decomposition and Leachates
As it decomposes, the chemicals in the rubber leach into the soil and nearby water sources. Many of these chemicals, as well as heavy metals, are dangerous to plants, soil and aquatic systems.
How do rubber tappers defend their position?
rubber tappers defend their position
byt saying that they have worked there for longer than most (not all) of the other interest groups
. They also say that their way of life doesn’t hurt the rainforest. So they can get the rubber out of the tree without hurting it.
