Elastomers.A useful reference chart, rating each of 16 traditional and advanced elastomers on hardness, tensile strength, elongation, heat resistance, chemical resistance and other properties, is available from the company. The chart, "Properties of selected elastomers," rates each elastomer elastomer (ĭlăs`təmər), substance having to some extent the elastic properties of natural rubber. The term is sometimes used technically to distinguish synthetic rubbers and rubberlike plastics from natural rubber. on a four-step scale from excellent to poor. Among the elastomers listed are natural rubber, synthetics in common usage such as EPDM EPDM Ethylene-Propylene-Diene-Monomer EPDM Enterprise Product Data Management EPDM Ethylene Propylene Dimonomer (industrial/commercial piping/plumbing components) EPDM Engineering Product Data Management , silicone, urethane urethane (yoor´ithān´), n ethyl carbamate used as an anesthetic agent for laboratory animals, formerly used as a hypnotic in humans. and polysulfide pol·y·sul·fide n. A sulfide compound containing at least two sulfur atoms per molecule. , and some of today's more exotic synthetic rubbers, such as fluoroelastomer and fluorosilicone. The chart is intended to be a single, convenient guide for chemists, designers and engineers for designing or specifying elastomers. Pelmor Laboratories www.pelmor.com |
