What Does Elastomeric Mean?

Elastomeric refers to the rubber-like properties of a polymer, i.e., a material being able to regain its original shape when a load is removed from the material. It is related to having the properties of elastomers.

Materials possessing elastomeric properties include both natural and synthetic rubber, urethane, polyurea and polymeric coatings.

Elastomeric materials are degraded by sunlight, ozone and oxygen. These three agents can seriously affect the properties and appearance of many elastomeric materials. These weathering agents can cause surface cracking, discoloration of colored stocks, and serious loss of tensile strength, elongation and the other rubber-like properties of elastomeric materials.


Corrosionpedia Explains Elastomeric

An elastomer is a rubber-like polymer that demonstrates an elastic behavior at the time of loading. In elastomeric materials, polymer molecules have weak interaction among them. Therefore, they regain their original shape after the removal of loads. This can be seen when stretching a coiled chain, which uncoils and snaps back to its original coil state when the force is removed. An elastomeric material has high tear strength, is dimensionally more stable in storage, highly waterproof and corrosion resistant. It has a wide field of applications such as paints, coatings, linings and roofing.

Elastomeric materials are used to protect against corrosion. They can be used as the lining of vessels or tanks, coatings of materials and water-resistant roofing.

Elastomeric materials are used to produce a variety of products, for example: hoses, cable insulation, o-rings, seals and gaskets, belts, vibration mounts, flexible couplings, expansion joints, electrical parts, and automotive and airplane parts.

Elastomeric or rubber materials are also used extensively as membranes in acid-brick lined vessels to protect the steel shell from corrosive attack. This lining also protects the elastomer from abrasion and high heat. Additionally, these materials are used for lining ponds and basins to prevent pond contaminants from seeping into the soil and causing groundwater and soil contamination.

Concrete paint is produced by mixing varnish with dissolved elastomeric materials. This paint is preferred where the combination of moisture and alkali cause the disintegration of ordinary paints and varnishes. These paints also provide a high degree of protection against corrosion when applied to steel.
