Polymer Latex in medical gloves

The latices used in the dipping process are almost exclusively natural rubber (NR), polyisoprene rubber (IR), acrylonitrile butadiene rubber (NBR) and chloroprene rubber (CR). The word latex formerly indicated the white, milky sap collected from the rubber tree, but with the marketing of CR emulsion polymerisation products, the term also came to be applied to dispersions of fine rubber particles in a liquid consisting primarily of water.

NR latex is an opalescent, viscous liquid secreted when the bark of the rubber tree is injured. It is an emulsion of rubber particles dispersed in aqueous solution as a colloid (particle size: 0.3-2.0 mm); as well as 35-50% of rubber, it contains small amounts of protein, resin, sugars, etc. The rubber particles are negatively charged and the disperse phase is positive.

On the other hand, latices of IR, NBR and CR, known collectively as synthetic rubber latices, consist of 0.1-1.0 mm polymer particles dispersed in water by virtue of a protective layer of surfactant, etc.

Ruico, as a listed chemical company in China, we have formulated a nitrile latex for surgical examination nitrile gloves...

RF-9619 is a butadiene-acrylonitrile copolymer emulsion designed for disposable medical examination gloves.

RF-9619 has high tensile strength, high chemical resistance used for supported glove applications like medical examination gloves.
