The advantages and disadvantages of various materials chemical resistant gloves


2020-06-12


Chemical laboratory workers often face various hand safety risks during experiments, such as contact with various chemicals and hot objects. To protect these risks, you must choose and use chemical protective gloves correctly. The protective gloves of different materials have different performances, advantages, and disadvantages. Zhengzhou Ann Kang Trading Co., Ltd introduces them, hoping to provide some help for you to choose protective gloves.

The advantages and disadvantages of various materials chemical resistant gloves

Natural rubber chemical resistant gloves

Natural rubber latex gloves are usually unlined and come in a variety of styles, including clean styles and sterile styles. These gloves can provide effective protection against alkalis, alcohols, and various chemically diluted aqueous solutions, and can better prevent the corrosion of aldehydes and ketones.

Advantages: low cost, good physical properties, heavy-duty models have good cut resistance and excellent flexibility.

Disadvantages: Poor protection against oils and organic compounds, risk of protein allergy. Easy to decompose and aging.

Nitrile rubber chemical resistant gloves

Nitrile rubber chemical resistant gloves are generally divided into disposable gloves. Medium-sized unlined gloves, and light-weight lined gloves, which can prevent the corrosion of grease, xylene, polyethylene, and aliphatic solvents. It also prevents most pesticide formulations and is often used in the use of biological ingredients and other chemicals.

Advantages: Wide range of use, and scratch resistance, puncture resistance, wear-resistance, and cutting resistance. Excellent physical properties, good flexibility, low cost, and other advantages.

Disadvantages: poor protection for many ketones, some aromatic chemicals, and moderately polar compounds.

Polyvinyl chloride (PVC) chemical resistant gloves

The thickened and treated surface (such as rough surface) can also prevent general mechanical wear, and the thickened type can also protect against cold. The operating temperature is -4℃~66℃. It can be used in a dust-free environment.

Classification standard of PVC gloves:

A grade product, no holes on the surface of the glove (with powder PVC gloves), the amount of powder is uniform, and there is no obvious powder. The size and physical properties of each part are in line with customer requirements.

Grade B products, slightly yellow in color, severe nail prints, cracks, the size, and physical properties of each part do not meet the requirements.

Advantages: Strong chemical corrosion resistance, can protect almost all chemical dangerous goods. Low cost, good physical properties, and the lowest risk of allergic reactions.

Disadvantages: Some organic solvents will wash off the plasticizer on the gloves. Some black spots or black holes may be left on the gloves, resulting in rapid penetration of chemicals and endanger the wearer's hand safety.

Leather gloves

Good mechanical wear resistance. The thick skin protects against heat, and the outer layer is aluminized to protect against high temperature and heat radiation. Spray leather is wear-resistant and anti-fouling. General protection against cold, heat, spark splash, wear, cut, puncture.
