The formal definition of a thermoplastic rubber or elastomer (TPE) is “a polymer blend or compound which, above its melt temperature, exhibits a thermoplastic character that enables it to be shaped into a fabricated article and which, within it’s design temperature range, possesses elastomeric behaviour without cross-linking during fabrication. Polymers with pendent bulky side groups, on the other hand, will undergo strain softening because radical recombination reactions are less likely to occur due to steric hindrance. N.p., 08 Dec. 2014. Main Difference – Plastic vs Rubber. Though "elastomer" is synonymous with "rubber", it is more formally a polymer that can be modified to a state exhibiting little plastic flow and quick or nearly complete recovery from an … Rubber is an example of an elastomer type polymer, where the polymer has the ability to return to its original shape after being stretched or deformed. Following its introduction, the usage of Viton spread quickly to other industries including the automotive, appliance, chemical, and fluid power industries thanks to its natural resistance to both fuel and oil. Thermoplastic elastomers (TPEs) are biphasic synthetic polymer materials consisting of a continuous soft rubbery matrix physically cross-linked by glassy plastic domains [1, 2] ().Such materials have the elasticity of a conventional rubber but are suitable for high-throughput plastic-processing techniques such as injection molding and melt extrusion without requiring a curing process [3, 4]. They have lower creep resistance than thermoplastic materials. A polymer is a macromolecule that is made out of many repeating units. All rights reserved. Rubber, for example, is a natural polymeric material that has been used for thousands of years. Elastomers are rubber like polymers and generally extensible, compliant and return to the original shape after deformation. Elastomer rubber compounds are made from five to ten ingredients, each ingredient playing a specific role. This causes reduction of plastic flow and allows the polymer to return to its original shape when stretched and released. They are lightly cross-linked and amorphous with a glass transition temperature well below room temperature. The difference between elastomer vs polymer is that elastomers are a unique polymer with unique characteristics and properties. Also known as thermoplastic rubber, a thermoplastic elastomer is a blend or compound of polymers that melt and form into plastic when heated. On a broad scale, polymers are described by molecular characteristics to include the repeat unit composition, chain shape (coiling, twisting, etc. It can be cured with sulfur or peroxide systems. A polymer is a giant molecule which is built out of small units called monomers. Plastic and elastomer are types of polymers.

Elastomers are a… Today, more than 32 synthetic rubbers are known, the most important ones are listed here.. Modern elastomeric sealing compounds generally contain 50 to 60% base polymer and are often described simply as “rubber.” Synthetic polymers are used daily in products all around us: clothing and carpets are made from polyester fibers, foam cushions and upholstery in furniture are made of polymers, polyethylene cups, pipes and valves, plastic bags, medical devices, cookware, rubber for tires and tubing, paints, electronic components, adhesives, and so on, are all examples of polymers. The basic core polymer of an elastomeric compound is called a rubber, produced either as natural gum rubber or manufactured synthetically by the chemical industry. Enclosed gas cells within the plastic will cause even dense polymers to float. In natural rubber, most of the double fonds formed in the polymer chain have the Z configuration, resulting in natural rubber's elastomer qualities. A = wt. Gel elastomers are highly viscoelastic polymer gels that have excellent shock absorption and damping characteristics. Plastic is a synthetic polymer whereas rubber is found as a natural polymer. Elastomer - definition, properties and examples of elastomer. In other words, the shape of an elastomer would momentarily change when a stress is applied, but it would obtain its original shape once the stress is relieved. Elastomer is a group that has been categorized according to its physical properties. Rubber vs. What is a Polymer Polymer is any giant molecule made out of repeating units. O-Ring Elastomers . The flexibility of a thermoset elastomer, like all thermosets, is limited to a degree with regard to reprocessing and recycling. Polymers can be either amorphous or semi-crystalline.

[99]. Vulcanization is the process where sulfur cross-links are introduced to natural rubber. The Polymer is defined as the macromolecule of organic compounds that are made up of many smaller subunits called monomers; on the other hand, elastomers are defined as the type of polymers that have the property of elasticity. Some polymers are synthetic whereas other polymers are naturally occurring compounds. Their versatility and usefulness make the application of elastomers popular in a wide variety of everyday products, from skateboard wheels and the soles of sneakers, to gaskets and electronic cabling and wire insulation. With this new hose we now have a lightweight hose that is 30-40% lighter than traditional rubber hose. However, thermoset plastics polymer chains are bonded via the stronger covalent bonds, which unfortunately will burn the polymer before the covalent bonds are broken. However, there is a need for more elastomers that perform at very low temperatures. Thermal coefficient larger than other elastomers, so seal housing size may need modifying. They can be envisaged as one very large molecule of macroscopic size. The basic core polymer of an elastomeric compound is called a rubber, produced either as natural gum rubber or manufactured synthetically by the chemical industry. Rubber would be a type of elastomer, nylon is a thermoplastic and epoxy is a thermoset. High cost, so generally used when no other elastomer is appropriate. From the simple usage of wood and cement to the invention of metal, mankind has really made great progress to become what they are today. Whether an amorphous polymer is a thermoplastic or an elastomer depends on its glass transition temperature, or T g. This is the temperature above which a polymer becomes soft and pliable, and below which it becomes hard and glassy. 1 The term is often used interchangeably with the term rubber.
