Quality and Relationship You Can Trust


Accelerated Aging   To derive an aging performance different from realtime aging, which is not practical for assessing product stability, accelerated aging is often applied. For gloves, accelerated aging as applied in ASTM D3578 standard specification requires the glove samples to be heated to 70 +/- 2 degree C for 166 +/- 2 hours and then tested for its tensile properties (tensile strength and ultimate elongation).
Accelerators   Accelerators are chemicals that help speed up the process of vulcanization. Typical accelerators used in glove manufacture are zinc diethyldithiocarbamate (ZDEC) and zinc dibutyldithiocarbamate (ZDBC).
Activators   Activators initiate reactions. They are essentially to kick-start the vulcanization processes. In glove manufacture, zinc oxide is the common activator used.
ADA   This is the acronym for American Dental Association. The ADA encourages the distribution of high quality dental products and offers a scheme whereby distributors may apply for their products to be tested to meet their stringent standards. Upon passing, such products may be allowed a seal of approval. ADA seal may be used domestically in the United States or internationally.
Aging   Process of glove deterioration. Antioxidants are added during compounding to improving aging characteristics of gloves. To extend shelf life, keep gloves in its original packing and away from heat, direct sun and fluorescent lighting.
Allergenic Proteins   These are proteins that cause allergy in some users. Some of these proteins are able to survive the glove manufacturing process. Currently the known ones are Hevein b1, b3, b5 and b6.02. These proteins are also called latex allergens.
Ambidextrous   That which can be used on either hand without compromising its function. Examination gloves are produced generally as ambidextrous, although there are some contoured exam gloves in the market. Due to the very flexible nature of the gloves and its short duration usage, ambidexterity is a common and accepted feature.
Anti-oxidants   Although natural latex contain some natural anti-oxidants to slow down its deterioration, artificial anti-oxidants may be added to enhance the storage life of the gloves. Still, the general precaution for glove storage is to avoid heat and direct sunlight and fluorescent lighting.
Antigenic Proteins   These represent the total protein, including those that are non-allergenic. As you can see, not all proteins cause allergy.
AQL   This is the acronym for Acceptable Quality Level and is most commonly used in reference to the pinhole level of a consignment of gloves tested or bought. For pinholes of medical gloves, the AQL is typically 1.5 or better.
ASTM   This is the acronym for American Society for Testing and Materials, which set standards and specifications of testing and devices. For example, rubber examination gloves are standardized using ASTM’s standard no. D3578.
Biocompatibility   Over the years of widespread glove usage, especially of latex gloves, a number of users have developed chemical and protein allergies to them. Biocompatibility involves testing the products to satisfy the requirement of NIL sensitization and irritation in accordance to a set protocol using the relevant regulations of the Consumer Product Safety Commission and the ASTM Standard F-720-81 (Re-approved 1986).
CE   This is a mark that is found on all products destined to the European Union. A ‘CE’ marking implies the product has been registered with the Competent Authority in which the product is exported into and that it is safe for use. Every ‘CE’ marked product need to be supported with a technical file. Gloves is currently classified as a class I medical device with minimal risks and may be self-declared to conform to EU Directive 93/42.
Chlorination   A process of making powder-free gloves by treating gloves with chlorine in solution. The process modifies the rubber surface making it non-tacky. It also removes surface protein to a negligible level. Chlorinated powder-free glove is the most common variant of powder-free gloves in the market.

Latex gloves are typically double chlorinated to ensure both glove surfaces receive sufficient treatment. Double chlorination also requires additional rinsing of the gloves, thereby making them cleaner. Double chlorination is carried out off line.

Chlorination may also be carried out online but this is done only on one surface and there is no multiple rinsing of the gloves. Single chlorinated gloves are not truly powder-free as the other surface, in contact with the mold, is not washed.
Compounding   A process of blending chemical slurries into stabilized latex to create a mixture called compounded latex. Chemical slurries typically contain sulfur, zinc oxide, ZDEC, ZDBC, titanium dioxide and anti-oxidant.
Contoured   This is also called hand-specific or anatomical which means that a left-handed glove may only be worn on the left and not on the right, and vice versa. Surgeon’s gloves are contoured to ensure they fit well over the hands to minimize fatigue. This requirement is very crucial during surgical operations where accuracy and control are important.
Cuff   Cuff is the open end of a glove through which the hand and fingers are inserted. Cuffs are usually beaded although non-beaded types are available but in lesser quantities. Beaded cuffs allow for easier wearing, as there is a ‘handle’ for the user to hold during donning. Cuffs also allow the glove to be opened more readily.
