Chemical resistant gloves and
liquid-resistant gloves are suitable to use for protection against intentional
contact—i.e., long-term exposure to significant amounts—with acids, alkalis,
and various other aqueous solutions. Depending on the particular chemical or
solvent used in the application, these types of gloves are available in a
variety of materials, including:
-
Nitrile:
Also known as nitrile butadiene rubber (NBR), this material is capable of
withstanding exposure to oils, greases, and acids. However, industry
professionals advise against using this material with ketones, strong
oxidizing agents, and organic nitrogen-based compounds. Nitrile gloves may
also be treated or lined with additional materials, such as neoprene, for
additional insulation and safety sealing purposes.
-
Polyvinyl Chloride (PVC): Commonly known
as vinyl chloride plastic, this waterproof material is suitable for use
when handling a range of detergents and aqueous solutions. PVC coated
gloves are commonly formulated to be germ resistant and may be used for
handling diluted oxidizing agents and oil-soaked components, but they are
not recommended for use with concentrated agents or solvents.
-
Butyl and Neoprene: Combinations of
these synthetic rubbers are used to produce gloves that are resistant to
various oils and petroleum. Neoprene is also suitable for protection
against alcohols, alkalis, and an array of hydraulic fluids and oil types,
while butyl resists oxidation and is commonly used for processes with
highly corrosive acids and solutions, such as nitric and sulfuric
substances.
-
Latex: Commonly used for light-duty
operations and medical and laboratory procedures, this type of glove is
suitable for complex and intricate operations as they are less bulky than
other, more durable and heavy-duty materials. Latex gloves are considered
multi-purpose gloves and are often used in cleanrooms and for processes
involving acid, ketone, and salt solutions. Additionally, they may be
treated with a polyurethane coating for cleanroom applications.
-
Polyethylene: Commonly used for
food handling operations, this material is used to fabricate thin,
disposable gloves for operations similar to those of latex. Manufacturers
also fabricate variations of these gloves that include liners for
sensitive skin types.
