Natural latex gloves

In the last few years, sensitizations to latex proteins have been found with increasing frequency (Rustemeyer et al. 1994 Wrangsjo et al. 1994 Munksgaard et al. 1996 Field 1997). In particular, powdered, natural latex gloves are considered to cause latex sensitization by exposure to aerosolized natural latex proteins (Field 1997)- Notably, powder contamination of dental implant sites may impair the long-term results and success of dental clinical procedures (Field 1997). 

In addition to the soHd form of natural mbber it is available as a soHd suspended in water, known as latex. Synthetic mbbers are also available in latex form. Latex has become an important commodity used in the manufacture of dipped goods for health and disease protection. The principal uses of natural mbber are as follows tires and retreading, 70% latex (gloves, balloons), 12% mechanical goods, 9% load-bearing components, 4% and other, 5%.

Latex gloves, balloons, condoms, and other elastomeric products are produced by dipping metal molds into a latex that can consist of either natural or synthetic rubber. The mold is pretreated with a chemical that causes the latex to coagulate on the mold. Then the latex-covered mold passes through an oven where the elastomer cures (crosslinks). A modem factory can produce on the order of a million latex gloves or balloons a day. 

Human natural killer (NK) lymphocytes are vital to immune system defense against viral infection. They are also crucial in protecting against primary tumor formation. In vitro exposures to low levels of two organotin pesticides, tributyltin (4.76) and triphenyltin (4.19), and two carbamate pesticides, maneb (0.62) and ziram (1.23), produced significant loss of cytotoxic function of NK cells after 6 days of exposure. The toxicities of the pesticides also increased very significantly with exposure durations J51 It should be noted that exposure to ziram can come from other sources. It is used as an additive in rubber products such as latex gloves. 

As a second example, latex, used to produce latex gloves, is a natural ingredient produced from tree sap, which varies in consistency with weather conditions and geographic location. Each batch of latex must be analyzed to determine its properties and then adjusted to get a more consistent performance. This is an example of a feed-forward control mechanism. One cannot set an operating window on the amount of solids added because it depends on the batch of latex. One cannot set an operating window on the percent solids in the latex initially because nature cannot be controlled. However, a control mechanism can still be established that ensures that the product will consistently meet requirements. Again adjustment mechanisms are required. 

Allergy to natural rubber latex, first reported in 1989 in the United States, is a common cause of occupational allergy for health care workers. Natural rubber is a processed plant product from the commercial rubber tree, Hevea brasiliensis. Latex allergens are proteins found in both raw latex and the extracts used in finished rubber products. Latex gloves are the largest single source of exposure to the protein allergens. ...

Elastomers, sometimes called rubber, are thermoplastic materials that become slightly crosslinked during their formation. Because of this, they stretch and bounce. Natural rubber (latex) is classified as an elastomer along with its synthetic counterparts. These types of poljmiers are used for things like latex gloves and rubber bands and b ls. 

Latex gloves are made of natural rubber. They are very flexible and thin and have excellent resistance against aqueous solutions, including acids and bases of modest concentration. They are not generally resistant to organic compounds. Their use over the years has decreased significantly since latex-based allergies are now more common. 

When one hears the word latex , one usually thinks of latex gloves. The natural mbber latex used in making gloves is one of the many different kinds of latexes present in common household products, including latex paints, floor polishes, paper, carpeting, nonwoven textiles, and adhesives. Latexes are often added or applied to commercial products with the intention of enhancing specific performance characteristics, including durability, chemical resistance, and dimensional stability (373). Latexes are also known as emulsion polymers, polymer dispersions, or polymer colloids. 

Natural rubber latex gloves plus inner gloves of plastic, nylon or cotton material reduce the risk of contact dermatitis and urticaria caused by latex rubber gloves. 

Natural rubber latex gloves plus latex or plastic gloves reduce the risk of blood-borne infections and/or chemical permeation.
