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.
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 ...
Vytex Natural Rubber Latex (NRL) is a brand of natural rubber latex produced and marketed by Vystar Corporation. Vytex NRL is an alternative material to petroleum-based synthetics and traditional (Hevea) natural rubber latex. Protein test results show that Vytex NRL typically has 90% fewer antigenic proteins than Hevea natural rubber latex.
Hevea brasiliensis is a tall deciduous tree growing to a height of up to 43 m (141 ft) in the wild. Cultivated trees are usually much smaller because drawing off the latex restricts their growth. The trunk is cylindrical and may have a swollen, bottle-shaped base. The bark is some shade of brown, and the inner bark oozes latex when damaged.
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 ...
A rubber band (also known as an elastic, gum band or lacky band) is a loop of rubber, usually ring or oval shaped, and commonly used to hold multiple objects together. The rubber band was patented in England on March 17, 1845, by Stephen Perry. [1][2][3] Most rubber bands are manufactured out of natural rubber as well as for latex free rubber ...
An alternative source of latex that is hypoallergenic, unlike the normal Hevea rubber, can also be extracted. [4] While Castilla elastica was the most widely used rubber source of Mesoamericans in pre-Columbian times, guayule was also used, though less frequently. [5] [6] The name "guayule" derives from the Nahuatl word ulli/olli, "rubber". [7]
FITkit is a method for quantification of the major natural rubber latex (NRL) specific allergens: Hev b 1, Hev b 3, Hev b 5 and Hev b 6.02. [ 1] The sum of four major allergens shows the allergenic potential of NRL products like gloves, condoms, teats, balloons, etc. These tests are based on the enzyme immunometric assay technique and use ...
