Rubber duck

A rubber duck or rubber ducky is a toy shaped like a stylized duck, generally yellow with a flat base. It may be made of rubber or rubber-like material such as vinyl plastic. Rubber ducks were inventeread more...d in the late 1800s when it became possible to more easily shape rubber, and are believed to improve developmental skills in children during water play. The yellow rubber duck has achieved an iconic status in Western pop culture and is often symbolically linked to bathing. Various novelty variations of the toy are produced, and many organisations use yellow rubber ducks in rubber duck races for fundraising worldwide.read less...

Rubber toughening

Rubber toughening is a process in which rubber nanoparticles are interspersed within a polymer matrix to increase the mechanical robustness, or toughness, of the material. By "toughening" a polymer itread more... is meant that the ability of the polymeric substance to absorb energy and plastically deform without fracture is increased. Considering the significant advantages in mechanical properties that rubber toughening offers, most major thermoplastics are available in rubber-toughened versions; for many engineering applications, material toughness is a deciding factor in final material selection.read less...

Rubber-tyred metro

A rubber-tyred metro or rubber-tired metro is a form of rapid transit system that uses a mix of road and rail technology. The vehicles have wheels with rubber tires that run on rolling pads inside guiread more...de bars for traction, as well as traditional railway steel wheels with deep flanges on steel tracks for guidance through conventional switches as well as guidance in case a tyre fails. Most rubber-tyred trains are purpose-built and designed for the system on which they operate. Guided buses are sometimes referred to as 'trams on tyres', and compared to rubber-tyred metros.read less...

Rubber (2010 film)

Rubber is a 2010 English-language French independent horror film about a tire that comes to life and kills people with psychokinetic powers. It was directed and written by Quentin Dupieux. The film waread more...s produced by Realitism Films. It was shown at the Cannes Film Festival in 2010, where it received positive reviews from critics.read less...

Rubber and PVC fetishism

Rubber fetishism, or latex fetishism, is the fetishistic attraction to people wearing latex clothing or, in certain cases, to the garments themselves. PVC fetishism is closely related to rubber fetishread more...ism, with the former referring to shiny clothes made of the synthetic plastic polyvinyl chloride (PVC) and the latter referring to clothes made of rubber, which is generally thicker, less shiny, and more matte than latex. PVC is sometimes confused with the similarly shiny patent leather, which is also a fetish material. Latex or rubber fetishists sometimes refer to themselves as "rubberists". Gay male rubberists tend to call themselves "rubbermen".read less...

Rubber elasticity

Rubber elasticity refers to a property of crosslinked rubber: it can be stretched by up to a factor of 10 from its original length and, when released, returns very nearly to its original length. This read more...can be repeated many times with no apparent degradation to the rubber. Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and technological importance. Elastomers have played a key role in the development of new technologies in the 20th century and make a substantial contribution to the global economy. Rubber elasticity is produced by several complex molecular processes and its explanation requires a knowledge of advanced mathematics, chemistry and statistical physics, particularly the concept of entropy. Entropy may be thought of as a measure of the thermal energy that is stored in a molecule. Common rubbers, such as polybutadiene and polyisoprene, are produced by a process called polymerization. Very long molecules (polymers) are built up sequentially by adding short molecular backbone units through chemical reactions. A rubber polymer follows a random, zigzag path in three dimensions, intermingling with many other rubber molecules. An elastomer is created by the addition of a few percent of a cross linking molecule such as sulfur. When heated, the crosslinking molecule causes a reaction that chemically joins (bonds) two of the rubber molecules together at some point. Because the rubber molecules are so long, each one participates in many crosslinks with many other rubber molecules forming a continuous molecular network. As a rubber band is stretched, some of the network chains are forced to become straight and this causes a decrease in their entropy. It is this decrease in entropy that gives rise to the elastic force in the network chains.read less...
