Acrylonitrile improves chemical resistance
Butadiene creates flexibility and tear resistance
The ceramic, hand-shaped formers are run through water and acid to clean them and remove residue. The formers are then dried to remove any remaining liquids.
The formers are dipped in a mixture of calcium carbonate and calcium nitrate to help the nitrile to solidify around the formers. The formers are then dried again.
The formers are dipped into a tank of NBR compound, which may include other additives and colors.
The NBR coating must be heated at a high temperature to form the gloves as they dry.
Gloves are then dipped in water tanks to remove all residues and extractable chemicals. This is crucial for medical and food-grade gloves.
Once leaching is compete, the cuffs are rolled to make the glove easier to remove and less likely to tear near the wrist. Gloves may undergo leaching again after beading.
At this point, gloves are treated to be easier to don. Traditionally, glove manufacturers used powders. These days, they are moving away from powdered gloves, which will be explored in the powder section To create a glove for easier donning, nitrile gloves undergo one of two processes:
This involves exposing the gloves to chlorine to make the material harder and slicker.
This lubricates the glove surface by adding a layer of polymer.
This is the final stage of production. Once the gloves are finished, workers remove them from the formers by hand.
