Thinner glove materials sacrifice chemical resistance to offer the best touch sensitivity and dexterity. Because surgical gloves are so thin, the material is easily stretched over the hand, allowing better sensitivity. But this stretching also leaves bigger spaces in the glove material at a molecular level. These larger spaces allow a chemical to permeate through very quickly, limiting the amount of time it can be worn. Some surgical nitrile gloves offer limited splash protection from chemicals. These gloves are not intended for complete immersion in chemicals, and should only be used for a very limited time period.
