Nitrile gloves have become a popular choice across various industries due to their impressive chemical resistance and durability. Made from nitrile butadiene rubber, these synthetic gloves provide a reliable barrier against a wide range of substances, including oils, fuels, and many solvents. Unlike latex gloves, nitrile gloves are hypoallergenic, making them safer for users with latex allergies. However, while they offer significant protection, it’s essential to understand their limitations, particularly against certain chemicals like ketones and strong acids. In this article, we’ll explore the composition, resistance capabilities, and best practices for using nitrile gloves to ensure optimal safety and effectiveness in your specific applications.
Nitrile gloves are made from a synthetic rubber called nitrile butadiene rubber (NBR). This material is a copolymer formed by combining acrylonitrile and butadiene. The acrylonitrile part gives nitrile its chemical resistance, while butadiene adds flexibility and strength. The balance between these two components affects the glove's durability and resistance to chemicals.
Because nitrile is synthetic, it contains no natural rubber proteins. This means it doesn't cause latex allergies, making it safer for many users. The manufacturing process also allows nitrile gloves to be produced in various thicknesses and textures, depending on their intended use.
Synthetic rubber like nitrile offers several benefits over natural rubber. It resists degradation caused by oils, fuels, and many solvents better than latex. This is because the polymer chains in nitrile are less likely to break down when exposed to harsh chemicals. The material also resists punctures and tears better, which is crucial in protecting hands during work involving sharp or abrasive objects.
The synthetic nature allows manufacturers to modify the glove's chemical composition to improve resistance to specific substances. For example, increasing acrylonitrile content improves resistance to oils and solvents but might reduce elasticity. This customization makes nitrile gloves versatile for many industries.
● Latex gloves come from natural rubber and offer excellent elasticity and comfort. They provide good protection against biological hazards but are less resistant to oils, fuels, and certain solvents. Also, latex can cause allergic reactions in some users.
● Vinyl gloves are made from polyvinyl chloride (PVC). They are inexpensive and suitable for low-risk tasks. However, vinyl gloves have poor chemical resistance and lower durability compared to nitrile and latex.
● Nitrile gloves strike a balance by offering superior chemical resistance, puncture resistance, and hypoallergenic properties. They are less flexible than latex but more durable. Compared to vinyl, nitrile gloves provide much better protection against chemicals and physical hazards.

This table helps highlight why nitrile gloves are often preferred for chemical handling and industrial use.
When selecting gloves, consider the specific chemicals and tasks involved to choose the best material and thickness for protection and comfort.
Nitrile gloves resist many common chemicals, making them a popular choice across industries. They handle oils, fuels, and greases well, which is why mechanics and automotive workers favor them. Weak acids and bases, such as diluted sulfuric acid or sodium hydroxide, are also manageable by nitrile gloves. Many household detergents and cleaning agents pose little threat to these gloves. They protect against vegetable oils, petroleum products, and some alcohols in low concentrations.
However, nitrile gloves don't resist all chemicals equally. They struggle against ketones like acetone and methyl ethyl ketone, which can permeate the material quickly. Strong acids, especially concentrated sulfuric or nitric acid, break down nitrile rapidly. Halogenated hydrocarbons (e.g., chloroform, methylene chloride) and aromatic hydrocarbons (such as benzene and toluene) also degrade nitrile gloves fast. For these chemicals, alternative glove materials are necessary.
Three key criteria help evaluate nitrile gloves’ chemical resistance:
● Degradation: This shows physical damage to gloves after chemical exposure, such as swelling, cracking, or softening. Detecting degradation early is critical since it compromises protection.
● Breakthrough time: The time between chemical contact on the glove’s surface and its detection inside the glove. Longer breakthrough times mean better protection. For example, a breakthrough time over 480 minutes is excellent for extended exposure.
● Permeation rate: The speed at which chemicals pass through the glove once breakthrough occurs. A slower rate offers more time before harmful amounts reach the skin.
Temperature, exposure duration, and hand movement affect these factors. Manufacturers test gloves under controlled conditions, but real-world use may vary. Always check chemical resistance charts and select gloves based on your specific chemicals and exposure times.
Nitrile gloves have limits. They are not suitable for prolonged contact with ketones, strong oxidizers, or concentrated acids. Even with chemicals they resist, extended exposure can degrade gloves faster. Thin disposable gloves offer splash protection but are not for immersion or long-term use.
Glove thickness influences protection. Thicker gloves provide longer breakthrough times and slower permeation rates but reduce dexterity. For heavy chemical handling, thicker or reusable nitrile gloves are better. For light tasks, thinner gloves may suffice.
Remember, no glove protects against every chemical. Always assess your hazards, consult compatibility charts, and replace gloves immediately if damaged or degraded.
Always consult chemical resistance charts before selecting nitrile gloves to ensure they match your specific chemical exposure and task duration.
Thickness plays a major role in how well nitrile gloves resist chemicals. Thicker gloves offer a stronger barrier, making it harder for chemicals to pass through. This means longer breakthrough times and slower permeation rates. For example, a glove that’s 8 mils thick will usually protect longer than one that’s 4 mils thick. However, thicker gloves can reduce your sense of touch and dexterity, making delicate tasks harder. So, choosing the right thickness depends on balancing protection and flexibility for your job.
Disposable nitrile gloves often come in thicknesses from 4 to 8 mils. For light chemical exposure, thinner gloves may be enough. But for heavy-duty work or longer contact, thicker gloves are better. Some reusable nitrile gloves can be even thicker, offering extra protection for harsh chemicals or prolonged use.
Glove size affects chemical resistance more than many realize. If gloves are too small, they stretch too much, thinning the material and weakening protection. Overstretching can cause micro-tears or make chemicals permeate faster. Gloves that are too tight also reduce comfort and increase hand fatigue.
On the other hand, gloves that are too large may bunch up, creating folds where chemicals can pool and penetrate. Poor fit can also reduce grip and control, increasing the risk of accidents.
The best approach is to choose gloves that fit snugly but comfortably. This ensures the material maintains its protective barrier and lets you work efficiently. Always check sizing charts from manufacturers and try different sizes if possible.
Environmental conditions impact nitrile gloves’ chemical resistance too. Temperature is a key factor; higher temperatures can speed up chemical permeation and glove degradation. For instance, a glove tested at room temperature may not perform as well in hot environments. Cold temperatures can make gloves stiffer and more prone to cracking.
Humidity and exposure duration also matter. Wet or sweaty hands inside gloves may weaken the material over time. Long exposure to chemicals, even those nitrile resists well, can eventually break down gloves.
Physical stress from hand movements, abrasion, or punctures can reduce resistance. Gloves under strain or damaged are less effective barriers.
To maximize protection, store gloves in cool, dry places away from sunlight or ozone. Replace gloves frequently during long tasks and inspect for signs of wear or damage.
Always select nitrile gloves with appropriate thickness and fit for your specific chemical exposure and environment to ensure optimal protection and comfort.
Nitrile gloves are widely used in healthcare because they provide excellent protection against bloodborne pathogens and many chemicals found in medical settings. They create a strong barrier during exams, surgeries, and lab work. Since nitrile is latex-free, it reduces allergy risks for patients and staff. Medical professionals rely on nitrile gloves for tasks like administering injections, handling medications, and cleaning wounds. Their puncture resistance helps prevent accidental exposure to infectious materials. Plus, nitrile gloves offer good sensitivity, allowing precise movements during delicate procedures.
In automotive repair and industrial work, nitrile gloves protect hands from oils, greases, fuels, and solvents. Mechanics prefer them because they resist tearing and chemical damage better than latex or vinyl. Nitrile gloves shield workers from hydraulic fluids, lubricants, and cleaning agents used in factories and workshops. Their durability stands up to rough surfaces and sharp parts. Industrial workers handling machinery or performing maintenance tasks benefit from nitrile’s strong barrier against contaminants and irritants. The gloves’ textured fingertips improve grip on oily or slippery tools, enhancing safety and efficiency.
Chemical plants and processing facilities often expose workers to hazardous acids, bases, and solvents. Nitrile gloves provide reliable protection against many of these substances, especially oils and diluted acids. They resist chemical breakdown better than latex, making them suitable for handling various chemicals safely. However, nitrile gloves are not ideal for all chemicals; strong ketones or concentrated acids require specialized gloves. In manufacturing, nitrile gloves help prevent chemical burns and skin irritation during mixing, transferring, or cleaning tasks. Their resistance to punctures and tears reduces the risk of accidental exposure in these demanding environments.
Always match nitrile gloves to your specific industry needs by checking chemical compatibility and selecting gloves with appropriate thickness and texture for the task.
Before putting on nitrile gloves, always inspect them closely. Look for holes, tears, or any discoloration that might indicate damage. Even tiny punctures can let chemicals through, so never skip this step. Make sure gloves fit your hands well — too tight stretches the material, making it thinner and easier to break. Too loose, and gloves bunch up, creating folds where chemicals might pool. A snug but comfortable fit keeps the protective barrier intact and lets you work efficiently.
Removing gloves properly is just as important as wearing them. Avoid touching the outside surface when taking gloves off to prevent contaminating your skin. Peel each glove off inside-out, holding the removed glove in the other gloved hand. Then slide fingers under the wrist of the remaining glove and peel it off over the first glove. Dispose of used gloves immediately in designated waste bins for hazardous materials. Never reuse disposable nitrile gloves; they lose their protective qualities after one use or if damaged.
After removing gloves, wash your hands thoroughly with soap and water. Gloves can have tiny leaks or become contaminated during removal, so handwashing eliminates any chemicals or pathogens you might have picked up. Use hand sanitizer if soap and water aren’t available, but soap is preferred. Maintaining good hand hygiene reduces the risk of skin irritation, infections, or chemical exposure even after glove use.
Always inspect nitrile gloves for damage before use, ensure a proper fit, and follow safe removal steps to maximize chemical protection and prevent contamination.
When choosing nitrile gloves, first think about the job. Different tasks require different levels of protection and dexterity. For example, healthcare workers need gloves that offer sensitivity for delicate procedures. Mechanics or industrial workers might need thicker gloves that resist oils and solvents better. Identify the chemicals you’ll handle and how long your hands will be exposed. For brief contact or splash protection, thinner gloves (around 4-6 mil) may work. For longer exposure or harsher chemicals, thicker gloves (8 mil or more) provide better resistance. Also, consider if you need disposable gloves or reusable ones for repeated use.
Not all nitrile gloves are created equal. Quality ratings help you pick gloves that meet safety standards. Look for certifications like EN 374 or ASTM F739, which test gloves against chemical permeation and degradation. These tests provide breakthrough times and permeation rates for specific chemicals. Gloves rated “Type A” under EN 374 resist more chemicals for longer times, suitable for heavy-duty work. Also, check manufacturer specs for thickness, tensile strength, and puncture resistance. Higher quality gloves last longer and protect better, which is crucial in hazardous environments.
Chemical resistance charts are valuable tools. They show how nitrile gloves perform against various chemicals, often using ratings like Excellent, Good, Fair, or Not Recommended. Find the chemicals you expect to encounter and check the glove’s rating. For example, nitrile gloves usually score “Excellent” against oils, fuels, and weak acids but “Poor” or “Not Recommended” for ketones like acetone. Remember, these charts are based on lab tests under controlled conditions. Real-world factors like temperature, glove thickness, and exposure time can affect performance. Always choose gloves rated for your specific chemicals and replace them regularly.
Always match nitrile gloves to your exact chemical exposure and task by checking quality ratings and resistance charts to ensure maximum hand protection and comfort.
