In the laboratory, people need to conduct various experiments, and each experiment is accompanied by risks. Therefore, in order to better protect themselves, people will protect each part of the body by using different labor protection products.


As the most vulnerable part of the external injury, the hand needs people to protect it. Therefore, when choosing hand protection gloves, people are more cautious.


According to the understanding of Yangyue Security, in the laboratory, commonly used labor protection gloves are divided according to materials, which can be divided into: natural latex, nitrile rubber, natural rubber, PVC (polyvinyl chloride), PVA (polyvinyl alcohol coating on the surface ), polybutylene rubber, butyl rubber, leather, cloth, etc.


So, with so many categories of laboratory gloves, how should people choose?


In fact, no matter what kind of labor protection gloves are used in the workplace, they need to be adapted to local conditions and selected according to actual needs.


Therefore, when choosing laboratory gloves, people can start from two aspects, one is the danger faced by the hands during the experiment, and the other is the laboratory gloves of different materials, what are the advantages and disadvantages. Only need to pass these two points, I believe that people can choose the right laboratory gloves.


So, what are the advantages and disadvantages of laboratory gloves of different materials?


The advantages and disadvantages of labor protection gloves of different materials in the laboratory


1. Natural latex:


Advantages: It has anti-skid grip, heat insulation, tear resistance, puncture resistance, abrasion resistance and anti-cutting properties. It also has good protection for water-based chemical products (such as acid and alkaline aqueous solutions), and it can be worn Comfortable and flexible, it is often used in oil-free working environments.


Disadvantages: The protection against organic solvents is not good enough, and it is not resistant to oil. At the same time, it may cause allergies in some people because some users will be allergic to milk protein.


2. Nitrile rubber


Advantages: This is the most common material in laboratory protective gloves. Not only can it prevent the corrosion of grease (including animal grease), xylene, polyethylene and aliphatic solvents, but it can also be waterproof and resistant to acid, alkali and Alcohol solvent has the advantages of high abrasion resistance, good heat resistance, low chemical residue on the surface, good flexibility and good sensitivity.


Disadvantages: Can not resist most ketones, aromatic chemicals, can not be used in high-temperature workplaces, nor can it be used as insulating gloves.


3. Natural rubber


Advantages: It has an effective protective effect on alkalis, alcohols and various chemically diluted aqueous solutions (such as dilute acids and dilute alkalis), and can better prevent the penetration of aldehydes and ketones. Therefore, it is often used to clean laboratory utensils and instruments.


Disadvantages: Poor protection against oils and organic compounds, and insufficient flexibility and sensitivity when wearing gloves.

4. PVC


Advantages: It has strong anti-chemical corrosion performance, and it also protects a large number of water solvent chemicals (such as acids, alkalis, amines, peroxides, etc.).


Disadvantages: It does not protect against organic solvents. If PVC gloves are used in organic solvents, the plasticizer in the gloves will dissolve, allowing chemicals to penetrate the hands quickly. If PVC gloves are used at high temperatures, the gloves will decompose and produce vinyl chloride (VCM).


5. PVA


Advantages: It has good chemical resistance, scratch resistance and abrasion resistance. It is also suitable for organic chemicals such as aliphatics, aromatic hydrocarbons, chlorinated solvents, fluorocarbons and most ketones (except acetone), esters and ethers. Play an effective protective role.


Disadvantages: When contacted with water, it will be quickly decomposed by water, so do not use it in water or water-based solutions.

6. Neoprene


Advantages: Good protection for petrochemical products, anti-slip agents, acids, alkalis, hydrocarbons, alcohols, phenols and other substances, so it is widely used in the chemical and petrochemical industries.


Disadvantages: cold resistance is relatively poor, so it is not suitable for low temperature operation environment.

7. Butyl rubber


Advantages: Not only protects acetone, acetonitrile, dimethylformamide, dimethyl sulfoxide and other substances, but also has excellent resistance to acids and oxidation-reduction solutions other than strong oxidizing concentrated acids, so it is more suitable for use Used to deal with toxic substances in the laboratory.


Disadvantages: poor protection against non-polar solvents.


8. Cloth


Advantages: It can prevent medium and low mechanical wear. The thickened cloth gloves can be used for heat and cold resistance, so it is more suitable for heating utensils in the laboratory.


Disadvantages: Can only be used for general protection, not for chemical protection.


9. Leather


Advantages: It has a certain protective effect on cold, heat, spark splash, wear, cut, and puncture, and it has good mechanical wear resistance. If it is thick leather gloves, it can prevent heat, if it is coated with aluminum on the outer layer, it can prevent High temperature and heat radiation. Therefore, it is often used in liquid nitrogen operation and welding operations.


Disadvantages: Can only be used for general protection, not for chemical protection.

The above are the advantages and disadvantages of the commonly used glove materials in laboratory gloves. I hope it will be helpful for everyone to choose the correct labor protection gloves.
