The difference between nitrile gloves and latex gloves

Nitrile rubber is produced by emulsion polymerization of butadiene and acrylonitrile. Its products have excellent oil resistance, high abrasion resistance and good heat resistance. It is made of high-quality nitrile rubber with other additives and refined and processed; it does not contain protein, has no allergic reaction to human skin, is non-toxic, harmless, durable, and has good adhesion. Nitrile gloves are widely used in housework, electronics, chemicals, aquaculture, glass, food and other factory protection, hospitals, scientific research and other industries.

Different from latex gloves, nitrile gloves are insoluble in non-polar solvents, (it can effectively withstand alkane, cycloalkane non-polar reagents, such as n-pentane, n-hexane, cyclohexane and other reagents are mostly marked as green It should be noted that for aromatic hydrocarbons, the protective performance of nitrile gloves is quite different. For example, in benzene, degradation grade P, the overall grade of degradation and penetration of gloves is marked as red. In toluene, degradation grade F, penetration time 34 minutes, the permeability F, the label is yellow. In xylene, the degradation grade G, the permeation time 96 minutes, the permeability F, the label is green. 50% sodium hydroxide, 10% hydrochloric acid, 47% sulfuric acid (battery Use acid), 30% hydrogen peroxide, etc. are all marked as green, degradation grade E, penetration time>360 minutes. Alcohols such as methanol, ethanol, n-propanol, pentanol, cyclohexanol, etc. are also marked as green. Butyronitrile Gloves have poor protection against dimethylformamide, acetone, methyl ethyl ketone, tetrahydrofuran, chloroform, dichloroethane, chlorobenzene, phenol, benzaldehyde, and ethyl acetate, and are marked in red.

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’s focus on this. Two gloves, respectively, introduce the difference between them. The advantages and disadvantages of nitrile gloves and latex gloves

Nitrile gloves material: NBR, a synthetic rubber of nitrile gloves, the main components are acrylonitrile and butadiene Advantages: no allergies, degradable, can add pigments, brighter colors

Disadvantages: poor elasticity, higher price than latex products, nitrile material has much better chemical resistance and acid and alkali resistance than latex, so it is more expensive

Latex gloves Material: natural latex (NR) Advantages: good elasticity, degradable Disadvantages: sensitization of some people The difference between nitrile gloves and latex gloves

(1) Material

Latex gloves are also called rubber gloves. Latex is a natural material, derived from rubber tree sap. Natural latex is a biosynthetic product. Due to differences in tree species, geology, climate and other related conditions, its composition and colloidal structure will often appear huge difference. In the fresh latex without any substance, the rubber hydrocarbon only accounts for 20%-40% of the total amount, and the rest is a small amount of non-rubber components and water. Non-rubber components include proteins, lipids, sugars and inorganic components. Some of them form a composite structure with rubber particles, and some are dissolved in whey or form non-rubber particles.

Nitrile gloves are the popular name for nitrile gloves. Nitrile is a kind of rubber and is a key raw material for organic synthesis and pharmaceutical intermediates. Mainly synthesized from acrylonitrile and butadiene. Nitrile (jīng): A type of organic compound with a special odor and decomposes when exposed to acid or alkali. 

(2) Characteristics

Latex gloves: Compared with nitrile gloves, the toughness and abrasion resistance are slightly inferior, but the elasticity is better, the abrasion resistance, acid and alkali resistance, and grease are slightly worse than nitrile, and the acid and alkali resistance is slightly better than nitrile. But it is not suitable for allergic skin and long-term wear. Nitrile gloves: The material is relatively hard, the elasticity is poor, the abrasion resistance is better, acid and alkali resistance (some nitrile gloves can not prevent acetone, strong alcohol), anti-static, and will not cause skin allergies, suitable People who are prone to allergies and wear it for a long time.
