Abstract:
Natural rubber (NR) gloves manufactured from NR latex are widely utilized in various applications as a personal protective device due to their exceptional barrier characteristics in infection control. However, the use of NR gloves was associated with concerns about an NR protein allergy. With comprehensive leaching procedures now a common practice in NR latex glove factories to eliminate latent rubber proteins and chemical allergens, occurrences and complaints of protein allergy from medical glove users have decreased drastically over the past two decades.

Abstract:
Glove tear or perforation is a common occurrence during various activities that require gloves to be worn, posing a significant risk to the wearer and possibly others. This is vitally important in a clinical environment and particularly during surgical procedures. When a glove perforation occurs (and is noticed), the glove must be replaced as soon as possible; however, it is not always noticeable.

Abstract:
Hevea brasiliensis natural rubber (NR) latex is a very important commercial source of elastomers. It is not only a source for dry NR rubber but also the feedstock for the latex glove dipping industry. The particles of freshly tapped latex are known to be stabilized by proteins and lipids that come with the latex from the tree. These non-rubbers [, especially proteins and lipids, confer to the rubber and latex excellent properties unsurpassed by any synthetic latex [. Recent structural studies of NR revealed that the NR molecules comprise of 2 trans-isoprene units connected to a long-chain cis-

Abstract Polypeptides of natural rubber latex (NRL) that elute from surgeon's gloves and other manufactured rubber products can sensitize exposed individuals and elicit severe hypersensitivity reactions. Previously, we showed that prohevein is a major allergen in NRL, the source material for rubber manufacturing. To analyze which region of the molecule carries the main IgE-binding epitope(s), we purified prohevein and its C-domain from NRL by gel filtration, reverse phase chromatography, and electroelution. In immunoblotting, prohevein bound IgE from 15 of 20 (75%), and the prohevein C-domain

However, poor elastic recovery of nitrile glove to compressive force also creates an aesthetic issue for customers with high levels of wrinkling after removing from glove box.

Abstract The radiation and peroxide vulcanizations of natural rubber latex are sharing the same problem which is low mechanical properties on their latex. This makes it unsuitable to be use in the production of premium latex products such as surgical glove. Moreover, there are some cases where the use of sensitizers in radiation vulcanization and activators in peroxide vulcanization tends to produced latex film with unpleasant smell and darken color respectively during the drying process. For this study, radiation of latex formulations based on 0.1 pphr of tert-butyl hydroperoxide and 0.06 pph

Abstract:
In 1987, when the U.S. Centers for Disease Control and Prevention recommended the use of universal precautions in response to the HIV/AIDS epidemic, the demand for medical gloves dramatically increased. Unfortunately, the manufacturing techniques for the most widely-used gloves—natural rubber latex—also changed, in order to expedite production. These changes resulted in an increase in latex allergies, because excessive residual proteins that cause allergies remained on the gloves and became airborne with the gloves’ high level of powder. This allergy concern is especially relevant in the schoo
