(noun) “a natural or synthetic polymer having elastic properties”– Oxford Languages
Elastomers are materials that regain their original shape and size after the removal of a load or stressor. These materials are able to stretch extensively without breaking and have a wide range of temperature resistance. The term elastomeric is used to describe any material that contains the properties of an elastomer.
Other elastomeric properties vary based on the type but generally involve:
- Compression Set
- Tensile Strength
- Abrasion Resistance
- Tear Strength
- Gas Permeability
- Elongation at Break

(noun) “a tough elastic polymeric substance made from the latex of a tropical plant or synthetically.”– Oxford Languages
Rubber is an elastic, durable, and waterproof substance created from both natural and synthetic materials.
Natural rubber is created through natural sources. Natural rubber is present within nature through different types of plants, including Hevea Brasiliensis (the “rubber” tree), the Panama rubber tree, rubber figs, and even common dandelions. However, Hevea Brasiliensis has long been the top source of natural rubber, as it is extracted from the tree in the form of latex.
Synthetic rubber is artificially produced through the polymerization of monomers into polymers. Due to this process, there are several different types of synthetic rubber that can be produced.
(noun) “any of a class of synthetic materials which are polymers with a chemical structure based on chains of alternate silicon and oxygen atoms, with organic groups attached to the silicon atoms.”– Oxford Languages
Silicone is a product manufactured from silicon, an element found in sand. It has both rubber- and plastic-like properties and can be shaped or formed, softened or hardened into basically anything. Silicone has many benefits including tolerance to low and high temperatures, thermal stability, excellent insulation properties, and resistance to water. It also carries flame-retardant properties and is less prone to deterioration than other materials.
(noun) “a synthetic material made from a wide range of organic polymers such as polyethylene, PVC, nylon, etc., that can be molded into shape while soft and then set into a rigid or slightly elastic form.”– Oxford Languages
Plastics are a wide range of polymer-based materials that are lightweight, durable, flexible, typically inexpensive to produce, and easily molded, extruded, or pressed into various shapes. There are different types of plastic, categorized by their structure, how they respond to heat, and whether they are naturally or synthetically derived.
Plastic is made through polymerization in chemical plants. Petroleum, natural gas, or crude oil undergo a process called fractional distillation to produce hydrocarbons. The hydrocarbons then undergo polymerization and receive additives for color, stability, and/or additional plasticity. Finally, the material is shaped by injection molding, blow molding, extrusion, or calendaring.

(adj) “denoting substances (especially synthetic resins) that become plastic on heating and harden on cooling, and are able to repeat these processes.”– Oxford Languages
Thermoplastic materials are plastics that become pliable or moldable when heated and re-solidify when cooled.
(noun) “a compound that softens when initially heated, but hardens permanently once it has cooled”– Oxford Languages
Thermosets are plastics that have been irreversibly hardened during the manufacturing process. In contrast to thermoplastic materials, thermosets cannot be melted for reshaping.
