Most rubber gloves are made from one of four materials: natural rubber latex, nitrile rubber, vinyl (PVC), or neoprene. The material determines how the glove feels, what it protects against, and who can safely wear it. Which one you encounter depends on the setting, whether that’s a hospital exam room, a chemistry lab, or under your kitchen sink.
Natural Rubber Latex
Natural rubber latex comes from the sap of the Amazonian rubber tree, Hevea brasiliensis. Workers score the bark in a process called tapping, and the milky fluid that seeps out is collected, stabilized, and shipped to glove factories. This raw latex is a complex mix of rubber particles, water, proteins, and lipids. The proteins are what give natural latex its excellent stretch and strength, but they’re also responsible for latex allergies.
Latex gloves have been the standard in medicine and food handling for decades because the material offers outstanding elasticity, comfort, and tactile sensitivity. The rubber molecules arrange themselves in an almost perfect structural pattern that lets the material stretch to several times its length and snap back. No synthetic material has fully matched that combination of strength and feel.
The downside is allergy risk. The proteins naturally present in the rubber can trigger an immediate immune reaction (Type I hypersensitivity) in sensitized individuals, causing hives, swelling, or in rare cases anaphylaxis. This is a separate problem from the skin rashes caused by chemical additives in the manufacturing process, which involve a slower, delayed immune response (Type IV hypersensitivity). Both reactions are well documented in healthcare workers who wear gloves daily.
Nitrile Rubber
Nitrile gloves are made from acrylonitrile butadiene rubber, a fully synthetic material with no latex proteins. Two chemical building blocks, acrylonitrile and butadiene, are linked together into long polymer chains. The acrylonitrile content typically ranges from 18% to 50%, and that ratio shapes the glove’s properties. Higher acrylonitrile means greater strength, heat resistance, and hardness, while lower levels improve flexibility in cold conditions.
The acrylonitrile component is what gives nitrile gloves their strong resistance to oils, fuels, and many solvents. This makes them a go-to choice in automotive shops, laboratories, and medical settings where chemical exposure is a concern. They’re also the default option for anyone with a latex allergy. Nitrile gloves have largely replaced latex in many hospitals and clinics for this reason, though they tend to feel slightly stiffer on the hand.
Vinyl (PVC) Gloves
Vinyl gloves are made from polyvinyl chloride, a rigid plastic that needs to be softened before it can work as a glove. On its own, PVC is hard and inflexible. Manufacturers add plasticizers, chemical compounds that wedge between the polymer chains and make the material soft and pliable. Common plasticizers include several types of phthalates, such as DEHP, DINP, DIDP, and DBP.
Vinyl gloves are the cheapest option and work fine for low-risk tasks like food service, light cleaning, or brief patient contact where barrier protection matters more than chemical resistance. They don’t stretch or conform to the hand as well as latex or nitrile, and they offer significantly less puncture resistance. For tasks involving solvents, oils, or sharp instruments, vinyl is not the right choice.
Neoprene
Neoprene, also called polychloroprene, is one of the oldest synthetic rubbers, first developed in 1930. It’s made by polymerizing chloroprene, a molecule whose chlorine atom gives the finished rubber unusual chemical resilience. Neoprene gloves resist hydraulic fluids, gasoline, alcohols, organic acids, and alkalis, making them a staple in labs and industrial settings where workers handle hazardous chemicals for extended periods.
Compared to natural rubber, neoprene is stronger, harder, and far less sensitive to temperature swings. Natural rubber can turn brittle in the cold and sticky in the heat, while neoprene stays stable across a wider range. It also resists degradation from ozone, sunlight, and weathering. Lab workers tend to favor neoprene for its combination of chemical protection and finger dexterity, which many thicker industrial gloves sacrifice.
Synthetic Polyisoprene
Synthetic polyisoprene is essentially a lab-made version of natural rubber. Its molecular structure mimics natural latex closely, with about 95 to 98% of its chains in the same arrangement found in rubber tree sap. The key difference is that it contains no plant proteins, eliminating the risk of Type I latex allergy.
This makes synthetic polyisoprene popular for surgical gloves, where the stretch and sensitivity of latex are hard to give up but allergy risk is unacceptable. The tradeoff is performance. Natural rubber benefits from the proteins and lipids embedded in it, which act as natural reinforcing agents. Without them, synthetic polyisoprene has noticeably lower tensile strength and doesn’t stretch as far before breaking. For a surgeon who needs the closest feel to latex without the allergy concern, though, it’s the best available compromise.
How Rubber Gloves Are Made
Regardless of the material, nearly all disposable rubber gloves are produced through a dipping process. Hand-shaped molds, called formers, move along a production line and pass through a series of tanks. First, the formers are coated in a coagulant, a chemical that causes the liquid rubber to cling and solidify on contact. Then they’re dipped into a tank of compounded latex or synthetic rubber. The rubber grabs onto the coagulant-coated mold and forms a thin, even layer.
After dipping, the gloves are dried and then go through a leaching step, where they’re rinsed in hot water to wash away residual chemicals and, in the case of latex gloves, excess proteins that could trigger allergies. The gloves are then vulcanized, a heat-curing step that cross-links the rubber molecules and transforms the soft, fragile film into a strong, elastic glove. Finally, the finished gloves are stripped off the formers, tested, and packaged.
Chemical Additives in the Curing Process
Raw rubber, whether natural or synthetic, is too weak and sticky to use as a glove on its own. Vulcanization fixes this, but it requires chemical accelerators to speed the process to a commercially practical pace. The most common accelerator families are thiurams, benzothiazoles, and carbamates. These are the chemicals responsible for Type IV contact allergies, the delayed skin rashes that some glove wearers develop over time.
Beyond accelerators, the rubber compound may include activators, antioxidants to prevent degradation, pigments for color, and fillers to adjust thickness and cost. Each of these adds a potential allergen or irritant, which is why “hypoallergenic” gloves are formulated to minimize or eliminate certain accelerator classes. If you develop a persistent rash from wearing gloves, a patch test can identify which specific chemical is the culprit.
The Ban on Powdered Gloves
Gloves were traditionally dusted with cornstarch powder to make them easier to pull on. In December 2016, the FDA banned powdered surgical and examination gloves in the United States, effective January 2017. The powder posed serious risks: when it contacted internal body tissue during surgery, it could trigger severe airway inflammation, hypersensitivity reactions, and the formation of granulomas (clusters of immune cells) or adhesions (scar tissue) that led to surgical complications. The powder also acted as a carrier for latex proteins, launching them into the air and increasing allergy risk for everyone in the room. Modern gloves use polymer coatings or chlorination to achieve a smooth interior instead.
