Immunology. Latex allergy is a medical term encompassing a range of allergic reactions to the proteins present in natural rubber latex. [1] It generally develops after repeated exposure to products containing natural rubber latex. When latex-containing medical devices or supplies come in contact with mucous membranes, the membranes may absorb ...
Medical glove. Medical gloves are disposable gloves used during medical examinations and procedures to help prevent cross-contamination between caregivers and patients. [1] Medical gloves are made of different polymers including latex, nitrile rubber, polyvinyl chloride and neoprene; they come unpowdered, or powdered with corn starch to ...
Rubber is a natural polymer of isoprene (polyisoprene), and an elastomer (a stretchy polymer). Polymers are simply chains of molecules that can be linked together. Rubber is one of the few naturally occurring polymers and prized for its high stretch ratio, resilience, and water-proof properties.
Tractor tires have substantial ribs and voids for traction in soft terrain. A tire (British spelling: tyre) is a ring-shaped component that surrounds a wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide traction on the surface over which the wheel travels.
In natural rubber, each cross-link produces a network node with four chains emanating from it. It is the network that gives rise to these elastic properties. Because of the enormous economic and technological importance of rubber, predicting how a molecular network responds to mechanical strains has been of enduring interest to scientists and ...
Vibration isolation. Vibration isolation is the prevention of transmission of vibration from one component of a system to others parts of the same system, as in buildings or mechanical systems. [1] Vibration is undesirable in many domains, primarily engineered systems and habitable spaces, and methods have been developed to prevent the transfer ...
Ramsay grease is an old composition of paraffin wax, vaseline and natural rubber, usable up to about 25 °C, for low vacuums to about 1 Pa. Krytox is a fluorether-based vacuum grease, useful from −75 to over 350 °C, not flammable even in liquid oxygen, and highly resistant to ionizing radiation. Polyphenyl ether greases
Styrene-butadiene or styrene-butadiene rubber (SBR) describe families of synthetic rubbers derived from styrene and butadiene (the version developed by Goodyear is called Neolite[1]). These materials have good abrasion resistance and good aging stability when protected by additives. In 2012, more than 5.4 million tonnes of SBR were processed ...
