Natural Rubber and Synthetic Rubber Preparation and Properties

Natural rubber. These are the elastomers which are obtained naturally. It is made up of solids particles suspended in milky white liquid, called latex that drips from the bark of tropical and subtropical trees. This latex rubber is mainly found in the countries like Brazil, India, Indonesia, Malaysia and Sri Lanka.

31.5: Natural and Synthetic Rubbers - Chemistry LibreTexts

Natural rubber is an addition polymer that is obtained as a milky white fluid known as latex from a tropical rubber tree. Natural rubber is from the monomer isoprene (2-methyl-1,3-butadiene), which is a conjugated diene hydrocarbon as mentioned above. In natural rubber, most of the double fonds formed in the polymer chain have the Z configuration, resulting in natural rubber's elastomer qualities.

COMPARING STRENGTH PROPERTIES OF NATURAL AND SYNTHETIC

The natural rubber is the most often used type of mixture of the rubber industry nowadays which is produced from the milk-like fluid (from latex) of certain tropical trees. The latex is a colloid state dispersion, the rubber is precipipated (killed) by acetic – or formic acid from it then is washed, pressed, dried or

Properties of synthetic rubber

In contradiction to natural rubber polymers, the synthetic rubber polymer has a short length and a low molecular weight. The flexible middle part of the molecule chain, also called an elastomer, is more stable with respect to ageing than its natural counterpart.

Preparation of Synthetic Rubber

3 Part 1. This preparation of Thiokol rubber is a two-step process. The first step is the preparation of sodium polysulfide by the reaction of sulfur, S8, with a strong base, sodium hydroxide, NaOH. S8 + 2 NaOH → Na2S8 At room conditions, sulfur is normally in the form of S8 rings and chains.

Natural Rubber / Latex – Production of Natural Rubber

Background. Natural rubber comes from the Havea brasiliensis tree, which grows in tropical regions. They typically reach 20-30 metres in height on rubber plantations, and are able to produce commercial quantities of latex at about 7 years of age, depending on climate and location. Economical life span of a rubber tree is between 10...
