How Latex Is Made Into Rubber

What is latex? lates is a milky white fluid from the rubber tree (hevea brasilienesis),wherein the rubber particles are dispersed in water.The tree secretes it is a protective fluid below the bark of the tree.It is a natural rubber which denser when compared to plastic foam like furniture foam or plastic foam.Generally, the bark is cut into thin layers for the latex to exude from the bark that gets collected in the collection vessel over a period of time (in hours).Properties some of the important properties of rubber are: dust proof mite resistant hypo-allergic long lasting applications of the below mentioned applications, more than half of the rubber is used in the adhesive industry.Dipped goods like gloves (both, industrial and household), surgical goods, balloons etc.Adhesives for shoes, labels, pressure sensitive tape, and envelopes molds for plaster, wax, cryogenic materials, cement manufacturing process like any other agribusiness industry, the gestation period for setting up a rubber industry is long.It takes 5-7 years for the tree to exude latex from the bark.The manufacturing and processing natural is a complicated task and time consuming.It involves botany chemistry and also expertise in harvesting the rubber trees.Here's how latex is made into rubber involving the following steps: planting the high-grade rubber trees seeds are sown in the nursery and the sapling is grown in the nursery up to 12 - 18 months.After this, bud grafting is done, by grafting a new bud with the rubber sapling.The grafted sapling is transplanted in the field followed by the sprouting of the bud.Emerging as a young rubber tree.150 trees per acre or 375 per hectare are planted and the is ready for harvest after 7 years tapping from 6 - 7 years of planting the rubber trees the tapping process begins for harvesting latex.It requires dexterously skilled labor to shave off a thin layer of the exuding bark about 0.84 cm deep.Irreparable damage is caused to the tree if the cut is too deep.The cut should be optimum that even a shallow cut will not secrete the maximum amount of latex from the bark.Now, the leaking latex is collected into the collection cups.Tapping is done for three times on consecutive days until scar of the bark reaches 1 foot from the ground level.The cut lump (the one that oozes first time after every cut for the day) constitutes the coagulated latex and then comes the liquid latex both of which are sent for processing by the factories.Liquid concentrate production the water is removed from 10% of the latex collected to produce liquid concentrate.This increases the volume of rubber by 60%.It done through a process called creaming wherein a chemical agent is added to the latex for it to swell and come up to the liquid surface.This concentrate is used for adhesive purposes.Dry stock production the remaining latex is coagulated with dilute acid like formic acid and led into the extrusion dryer to remove water.It produces 1816 kg of rubber per hour sheet formation the rubber is diluted in aid to form smoked sheets.The rubber coagulates and the excess liquid is removed using rollers.The rubbers sheets are dried for about a week before it is shipped.
