latex gloves vs nitrile gloves,what is the difference between them?

Time:2021-05-15 15:27

During the novel coronavirus epidemic, front-line medical staff must be in close contact with a large number of patients every day. In addition to wearing professional protective masks, a pair of safe and durable nitrile medical gloves is also an important line of defense to protect them. Medical gloves can be divided into nitrile gloves, PVC gloves and latex gloves according to their materials. Nitrile gloves are made of nitrile latex, which has excellent fit and durability, stretch rate and excellent oil resistance, and the made gloves have more obvious advantages in organic solvent resistance and puncture resistance . Compared with PVC and latex gloves, nitrile gloves are stronger and more breathable. In addition, since nitrile gloves do not contain protein, they are unlikely to cause allergic reactions in allergic people.
Let's first understand, what are latex gloves and nitrile gloves?
Latex gloves
    Latex gloves are made of natural rubber collected from rubber trees. These gloves are thin and comfortable to wear. They conform to the shape and fit of your hand. This makes them very comfortable to wear. Because of their fit, they provide a high degree of flexibility. Wearing latex gloves will not feel discomfort or restricted hand movement. Latex gloves are indispensable hand protection products in household, industrial, medical and beauty industries. Latex gloves are made of natural latex and processed with other fine additives. After a special surface treatment, they are comfortable to wear and have a wide range of applications in industrial and agricultural production, medical care and daily life.

Nitrile gloves
    Nitrile gloves (ie, NBR gloves) are synthesized from acrylonitrile and butadiene. The production of nitrile gloves stems from the allergies of natural rubber and the limitations of raw materials. It is an intermediate product between latex gloves and PVC gloves. Nitrile gloves and latex gloves are widely used in electronic processing, mechanical processing, food processing and other industries. Because they are disposable gloves, many people do not know how to buy gloves when they buy gloves. Let us focus on this. Two pairs of gloves introduce the difference between them. Nitrile latex is a liquid synthetic latex with a milky white luster. It has excellent stretchability and oil resistance. It is mainly used for synthetic rubber products, such as medical glove materials.

    Nitrile and latex gloves are widely used in industry, medical and other industries, but because they are both disposable gloves, many people do not know the difference between the two. Let's take a look at the essential differences between them and how they should be distinguished.
We can distinguish by the following nine methods.
1. Material difference
    Latex gloves are also called rubber gloves. Latex is a natural material extracted from the sap of rubber trees. Natural latex is a biosynthetic product. Its composition and structure usually vary greatly depending on the type of tree, geology, climate and other related conditions. In the fresh latex without any substance, rubber hydrocarbons only account for 20% to 40% of the total, and a small amount of non-rubber components and water remain. Non-rubber components include proteins, lipids, sugars and inorganic components. Some of them form a composite structure with rubber particles, while others dissolve in whey or form non-rubber particles.

    NBR is a kind of synthetic rubber, mainly synthesized from acrylonitrile and butadiene, and is a key material for organic synthesis and pharmaceutical intermediates. First, the rubber is extracted from the rubber tree. It is then converted into latex rubber, and then processed again until it becomes a nitrile compound material. Nitrile gloves have good chemical properties, flexibility and tear resistance, so they are often used in daily life, chemical experiments and other applications.

2. Classification differences
    Latex gloves are divided into ordinary powder type and powder-free purified type, with a smooth and sunken surface.
    The models of nitrile gloves are divided into palm numb non-slip surface and hand tip numb non-slip surface. The overall numb non-slip surface is usually free of dust.
3. Anti-allergy
    Latex gloves contain protein and are not suitable for allergic skin and long-term wear.
    Nitrile gloves do not contain protein, amino compounds and other harmful substances, rarely cause allergies, and are more suitable for most people (less than 1% of allergic people).
4. Degradability
    Both latex and nitrile gloves are biodegradable, easy to handle and environmentally friendly.
5. Puncture resistance
    The toughness and abrasion resistance of latex gloves are higher than that of nitrile gloves.
    The puncture resistance of nitrile gloves is three to five times higher than latex. For dentists who need to use sharp tools, use durable nitrile gloves to form a safer barrier when in contact with patients.
6. Agile
Latex gloves: better flexibility, abrasion resistance, acid and alkali resistance, grease resistance than nitrile rubber, slightly better acid resistance than nitrile rubber
Nitrile gloves: less elasticity, better abrasion resistance, acid and alkali resistance, antistatic
7. Suitable for hand shape
    Since nitrile gloves contain butadiene monomers, they can be soft rubber so that the wearer can experience the best touch. In addition, the fit of the hand is also attributed to its good thermal conductivity, which provides excellent flexibility, which is especially important for medical professionals or those handling small parts or tools.
8. Price
    Nitrile gloves are more expensive than latex products because the material has better chemical, acid and alkali resistance than latex.
9. Color
    Nitrile materials can add pigments and brighter colors. It can reduce the tension of the patient.
    In addition, nitrile gloves have certain antistatic properties due to their non-siloxane content, low surface chemical residues, low ion content and small particle content. They are suitable for strict clean room environments.
    In general, gloves are not absolutely good or bad, and people can choose the right gloves according to their needs. Whether it is latex gloves or nitrile gloves, they have their own characteristics, and their biggest feature is "degradable" environmental protection gloves. Green and environmental protection are the greatest concern for our planet.
