Latex vs. Nitrile Disposable Gloves

　　Let me explain the pros and cons of disposable latex and nitrile gloves, and which one is superior!

　　1. Raw Material Differences

　　Disposable latex gloves, also known as rubber gloves, are made from natural raw materials derived from rubber tree sap. Natural latex is a microbial product. Due to variations in plants, environmental conditions, and climate, its composition can vary significantly. Hydrocarbons only account for 20%-40% of the total output; the rest is non-hydrocarbon components and water. Non-hydrocarbon components include proteins, lipids, glycogen, and inorganic substances; some combine with rubber particles, while others dissolve in the whey protein or form non-rubber particles. Nitrile rubber is a synthetic rubber produced from acrylonitrile and butadiene, and is a key raw material in chemical and pharmaceutical industries.

　　2. Classification Differences

　　Latex gloves are classified into powdered general-purpose and powder-free sterile types, with smooth and textured surfaces. Nitrile gloves are classified into palm-textured, fingertip-textured, and fully-textured types, generally powder-free.

　　3. Allergy Resistance

　　Latex gloves are rich in proteins, making them prone to causing allergic reactions. Nitrile gloves are free of proteins, methyl compounds, and harmful substances, resulting in significantly fewer allergic reactions.

　　4. Degradation

　　Both latex and nitrile gloves are biodegradable and easily disposed of, benefiting the environment.

　　5. Puncture Resistance

　　Latex gloves have slightly lower plasticity and wear resistance compared to nitrile gloves. Nitrile gloves have three to five times the puncture resistance of latex gloves. Their durability makes them ideal for dentists working with sharp instruments, providing a safer barrier during patient interaction.

　　6. Plasticity

　　Latex gloves are soft and durable, with better plasticity than nitrile gloves.

　　7. Dexterity

　　The single butadiene component in nitrile gloves allows for a flexible rubber, providing wearers with better tactile sensitivity. In addition, its good heat transfer properties contribute to better dexterity, which is particularly important for medical professionals or those handling small components or specialized tools.

　　Disposable latex gloves are categorized into three levels:

　　1. Powdered disposable latex gloves, mainly used in industries, require the addition of powder during production to prevent the gloves from sticking together and facilitate donning. The quality of the cornstarch is crucial.

　　2. Powder-free disposable latex gloves, mainly used in electronics and medical device industries, are cleaned with tap water during manufacturing.

　　3. A type of disposable latex glove mainly used in precision industries and the pharmaceutical industry for sterilization. These are powder-free latex gloves that have been cleaned with warm water and then further cleaned with chlorine, achieving a cleanliness level of 1000.
