Characteristics Of Rubber Polymer

The first synthetic manufactured plastic was bakelite created in 1909 for telephone casing and electrical components.

Characteristics of rubber polymer.

Polymers range from familiar synthetic plastics such as polystyrene to. Charles goodyear accidentally discovered that by mixing sulfur and rubber the properties of the rubber improved in being tougher resistant to heat and cold and increased in elasticity. As nouns the difference between polymer and rubber is that polymer is organic chemistry a long or larger molecule consisting of a chain or network of many repeating units formed by chemically bonding together many identical or similar small molecules called monomers a polymer is formed by polymerization the joining of many monomer molecules while rubber is. This article reviews the composition structure and properties of both natural and synthetic elastomers.

Natural rubber also called india rubber latex amazonian rubber caucho or caoutchouc as initially produced consists of polymers of the organic compound isoprene with minor impurities of other organic compounds plus water thailand and indonesia are two of the leading rubber producers. Due to their broad spectrum of properties both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Natural rubber is still an important industrial polymer but it now competes with a number of synthetics such as styrene butadiene rubber and butadiene rubber which are derived from by products of petroleum and natural gas. Starch can be a polymer as is cellulose in wood.

Rubber tree latex and cellulose have been used as raw material to make manufactured polymeric rubber and plastics. However the majority of polymers or plastics used for engineering design are synthetic and often they are specifically formulated or designed by chemists or chemical engineers to serve a specific purpose. Natural polymers include such materials as silk shellac bitumen rubber and cellulose. Types of polyisoprene that are used as natural rubbers are classified as elastomers.

The elastic properties arise from the its ability to stretch the chains apart but when the tension is released the chains snap back to the original position. Natural rubber is an addition polymer that is obtained as a milky white fluid known as latex from a tropical rubber tree.
