An elastomer is a polymer with viscoelasticity, which simultaneously exhibits the properties of a very thick fluid and a flexible solid.Thermoset elastomers are a class of polymers that are cured by cross linking molecular chains during the molding process, which requires the right amount of pressure and temperature to set the part into its permanent shape. Unlike plastics, which can break under pressure or melt in intense heat, rubber and elastomers hold up well to dynamic operating conditions, temperature variations, and harsh environments.
Rubber is the common name used for a variety of elastomers, but natural rubber is one of the least commonly used materials in industrial applications. When selecting the right elastomer for the application, our chemists and engineers consider such factors as the part’s operating conditions and the material’s ability to resist such environmental hazards as contact with oil and other fluids, abrasion, and temperature fluctuations, as well as the material’s cost.
In preparing a rubber compound for a specific application, we develop a recipe of the proper elastomer plus a mix of specialized additives to address such issues as resistance to UV, ozone or oil, bonding, and electrical conductivity.
