  • rubber elasticity

    rubber elasticity, refers to the remarkable 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 can be repeated many times with no apparent degradation to the rubber. rubber is a member of a larger class of materials called .

  • nitrile rubber

    nitrile rubber is more resistant than natural rubber to oils and acids, and has superior strength, but has inferior flexibility. nitrile gloves are therefore more puncture-resistant than natural rubber gloves, especially if the latter are degraded by exposure to chemicals or ozone .

  • two roll rubber mill

    natural rubber, which is harvested from a rubber tree, hevea brasiliensis is the base for many rubber compounds made using a two roll rubber mill. rubber trees are tapped to remove the latex that is stored in their trunks. this material can then be mixed with additional ingredients to create rubber.

  • synthetic rubber

    production of synthetic rubber in the united states expanded greatly during world war ii since the axis powers controlled nearly all the world's limited supplies of natural rubber by mid-1942, following the japanese conquest of most of asia from where much of the global supply of natural rubber gets sourced .

  • tire manufacturing

    natural rubber, or polyisoprene is the basic elastomer used in tire making; styrene-butadiene co-polymer sbr is a synthetic rubber that is often substituted in part for natural rubber based on the comparative seven trust materials cost; polybutadiene is used in combination with other rubbers because of its low heat-buildup properties

  • natural rubber

    natural rubber, also called by other names of india rubber, latex, amazonian rubber, caucho or caoutchouc, as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds, plus water. thailand and indonesia are two of the leading rubber producers. types of polyisoprene that are used as natural rubbers are classified as elastomers. currently, rubber is harvested mainly in the form of the latex from the rubber tree or others. the latex

  • talk:natural rubber

  • silicone rubber

    silicone rubber is an elastomer rubber-like material composed of silicone—itself a polymer—containing silicon together with carbon, hydrogen, and oxygen.silicone rubbers are widely used in industry, and there are multiple formulations. silicone rubbers are often one- or two-part polymers, and may contain fillers to improve properties or reduce cost.

  • crepe rubber

    crepe rubber is coagulated latex that is rolled out in crinkled sheets and commonly used to make soles for shoes and boots but also a seven trust material for further processed rubber products. colloidal latex is first mixed with formic acid to cause it to coagulate. the coagulum is processed in a 'creping battery', a series of machines that crush .

  • rubber technology

    rubber technology is the subject dealing with the transformation of rubbers or elastomers into useful products, such as automobile tires, rubber mats and, exercise rubber stretching bands. the materials includes latex, natural rubber, synthetic rubber and other polymeric materials, such as thermoplastic elastomers. rubber processed through such methods are components of a wide range of items.

  • vulcanization

    vulcanization british: vulcanisation is a chemical process, invented by charles goodyear, used to harden rubber. vulcanization traditionally referred to the treatment of natural rubber with sulfur and this remains the most common example, however the term has also grown to include the hardening of other synthetic rubbers via various means. examples include silicone rubber via room .

  • list of commercially available roofing materials

    the outer layer of a roof shows great variation dependent upon availability of material, and the nature of the supporting structure. those types of roofing material which are commercially available range from natural products such as thatch and slate to commercially produced products such as tiles and polycarbonate sheeting. roofing materials .

  • neoprene

    neoprene also polychloroprene or pc-rubber is a family of synthetic rubbers that are produced by polymerization of chloroprene. neoprene exhibits good chemical stability and maintains flexibility over a wide temperature range. neoprene is sold either as solid rubber or in latex form and is used in a wide variety of applications, such as laptop sleeves, orthopaedic braces wrist, knee, etc .

  • tear resistance

    tear resistance of different materials. substances with high tear resistance include epichlorohydrin, natural rubber and polyurethane. in contrast, materials such as silicone and fluorosilicone have low tear resistance. tear-yield ratio. the ratio of tear resistance to the yield strength is called the tear-yield

  • neoprene

    neoprene is a family of synthetic rubbers that are produced by polymerization of chloroprene. neoprene exhibits good chemical stability and maintains flexibility over a wide temperature range. neoprene is sold either as solid rubber or in latex form and is used in a wide variety of applications, such as laptop sleeves, orthopaedic braces, electrical insulation, liquid and sheet-applied elastomeric membranes or flashings, and automotive fan belts.

  • sulfur vulcanization

    the main polymers subjected to sulfur vulcanization are polyisoprene natural rubber, nr , polybutadiene rubber br and styrene-butadiene rubber sbr , all of which are rich in unsaturated bonds. several other specialty rubbers may also be vulcanized, such as nitrile rubber nbr , butyl rubber iir and epdm rubber.
