Unreferenced date December 2006 Context date October 2009 Rubber technology is the subject dealing with the transformation of rubber s or elastomer s into useful products, such as automobile tire s.The materials includes latex , natural rubber , synthetic rubber and other polymeric materials, such as thermoplastic elastomer s. Vulcanization Most rubber products are vulcanized , a process which involves heating with a small quantity of sulphur or equivalent cross linking agent so as to stabilise the polymer chains, over a wide range of temperature. This discovery was made by Charles Goodyear in the 1844, but is a process restricted to polymer chains having a double bond in the backbone. Such materials include natural rubber and polybutadiene . The range of materials available is much wider however, since all polymers become elastomeric above their glass transition temperature . However, the elastomeric state is unstable because chains can slip past one another resulting in Creep deformation creep or stress relaxation under static or dynamic load conditions. Chemical cross links add the stability to the network that is needed for most practical applications. Processing of Rubber Methods for processing rubber include mastication and calendering , both processes being essential to bring crude rubber into a state suitable for shaping the final product. The former breaks down the polymer chains, and lowers their molecular weight so that viscosity is low enough for further processing. After this has been achieved, various additions can be made to the material ready for cross linking. Rubber may be masticated on a two roll mill or in an internal mixer, such as a Banbury mixer . Rubber is first compounded with additives like sulphur, carbon black and accelerators. It is converted into a dough like mixture which is then milled into sheets of desired thickness. Rubber may then be extruded or molded before being cured. DEFAULTSORT Rubber Technology Category Rubber Category Manufacturing ... more details

Smart rubber is a polymer that is able to heal when torn. The edges of a tear can be held together, and they will simply re bond into apparent solidity. How it works This is done by producing a polymer that depends only on hydrogen bond ing to hold itself together, rather than also on covalent bond ing and ionic bond ing, which are present in normal rubber. Unlike the latter two types, hydrogen bonding can occur simply by pressing two faces of a substance together. Real world versions Materials of this type are still in development, for example a type invented at the Industrial Physics and Chemistry Higher Educational Institution ESPCI in Paris, France . Their translucent, yellowish brown rubber is synthesized from fatty acid s and urea . It is still too soft for most anticipated practical applications, like rubber gloves and shoe soles http technology.newscientist.com channel tech dn13354 smart rubber promises selfmending products.html?feedId online news rss20 . Among the potential problems of the material is that it would also bond to itself any other way it came into contact, like upon closing the fingers or hand of a glove. This may be solved by coating objects made from the rubber with some other polymer, so that the smart rubber is only exposed when torn. chemistry stub polymer stub Category Rubber Category Smart materials ... more details
Image Gummihose 6.jpg thumb 250px Rubber pants about 1950 Rubber pants or rubber panties were the predecessor to plastic pants and served the purpose of a diaper cover, replacing the woolen garment. However, rubber pants is still a generic term for any pull on or snap on incontinence protective garment. Lacking a fly front, the traditional variant is a true panty. As an infants garment they had fallen out of favor in the 1950s, but were still the primary adult incontinence protective garment and in that role were called rubber bloomers . Rubber pants for infants wear over cloth diapers fell into two categories. Some were made of natural rubber and had rubber gathers at the waist and legs. The rubber pant itself was sized generously so the stretchy characteristic of rubber was not utilized and some air circulation took place within the oversized pants. Some were made of latex rubber that utilized the stretchy characteristic and fit very snugly over the diaper, leaving no air space. Perhaps the best known of these stretchy latex pants were introduced by Playtex . Playtex baby pants stretched over the diaper much like rubber gloves are stretched over a hand. Undersized leg holes and waist opening allowed the stretchy latex rubber to seal against the skin to contain diaper wetness and therefore protect what ever the baby was placed upon. Ventilation was supposedly provided by two slots holes in the front of the pants up near the waist but they did little more than allow leakage onto the bed when baby slept on its stomach. Stretchy, molded latex pants for adults are mostly limited to the fetish market, being supplied primarily as wear for rubberist s , who enjoy wearing rubber and latex.
