elastomer

(ĭlăs`təmər), substance having to some extent the elastic properties of natural rubberrubber,
any solid substance that upon vulcanization becomes elastic; the term includes natural rubber (caoutchouc) and synthetic rubber. The term elastomer is sometimes used to designate synthetic rubber only and is sometimes extended to include caoutchouc as well.

. The term is sometimes used technically to distinguish synthetic rubbers and rubberlike plastics from natural rubber.

elastomer

[i′las·tə·mər]
(materials)
A polymeric material, such as a synthetic rubber or plastic, which at room temperature can be stretched under low stress to at least twice its original length and, upon immediate release of the stress, will return with force to its approximate original length.

elastomer

A macromolecular material (such as rubber or a synthetic material having similar properties) that returns rapidly to approximately the initial dimensions and shape after substantial deformation by a weak stress and release of the stress.

elastomer

(ELASTic pOlyMER) A soft, compliant, rubber-like material. See elastomeric connector.

As it is observed, in PDMS membranes as rubbery polymers, selectivity of larger gases over smaller gases increases with enhancement of feed pressure.
At rubbery polymer of PDMS in comparison with glassy polymer of PES, penetrant solubility coefficient is more important than diffusion coefficient.
The distribution of strands, p(n), in an unfilled rubbery polymer is characterized by a relatively small standard deviation [[SIGMA].
Conversely, addition of a rubbery polymer such as the EO copolymer decreases the stiffness but increases the elongation at break and provides improved impact resistance.
Topics of the 17 papers include glassy and rubbery polymers, highly permeable polymers, glassy polymers, substituted polyacetylenes, perfluoropolymers, polyimides, zeolite membranes, carbon membranes, polymer membranes for organic liquids, solid-state facilitated transport membranes for the separation of olefins/paraffins and oxygen/nitrogen, using a unified approach to membrane permeation using a solution-diffusion model, and using such methods as positron annihilation lifetime spectroscopy for free volume evaluation in polymers.
Polymers and other organic materials are typically much more compliant compared to the metallic and ceramic types of materials to which instrumented indentation mainly has been applied, with modulus values ranging from a few GPa for common glassy polymers to a few MPa or lower for rubbery polymers and many biological materials.
Biomed structures Chemists synthesized new gelatinous and rubbery polymers that may serve as superior dressings for wounds (162: 20) and as scaffolds for artificial organs and tissues (161: 323,408; 162: 93).
And rubbery polymers, while robust, have so far performed poorly as carriers of current.
The amine functionalized rubbery polymers can be utilized in tire tread rubbers where the rubbery polymers may provide desirable wear properties without substantially sacrificing other performance characteristic(s), e.
Since polyurethanes chains easily form hydrogen bond, these polymers can be very crystalline, so they are frequently used to compose block copolymers (having the properties of thermoplastic elastomers) with soft rubbery polymers.
