Differences between Ding Qing gloves, PVC gloves and latex gloves

With the outbreak of the epidemic, the market demand for disposable protective gloves has also increased dramatically. In fact, disposable gloves can be divided into Ding Qing gloves, PVC gloves and latex gloves according to the material. So what's the difference between them? Today, Xiao Bian leads us to distinguish.
First of all, from the material point of view, nitrile gloves are NBR, a kind of synthetic rubber, mainly composed of acrylonitrile and butadiene; PVC gloves are made of PVC; Latex gloves are made of natural latex (NR). What are their advantages and disadvantages?
The material of Ding Qing gloves is degradable, it will not be allergic to wear, it can add pigment, and the color is bright. The disadvantage is that the elasticity is poor, and the price is higher than that of latex gloves; PVC gloves have the advantages of low price and can add pigments to create bright colors. The disadvantages are that they contain high plasticizers, which are internationally recognized as public enemies of health. They are easy to volatilize harmful gases when heated, and they are non degradable; As for latex gloves, their advantages are degradable and elastic. However, some people may suffer from skin allergy if they wear latex gloves for a long time.
What about their anti-static performance? ESD refers to the anti-static performance of products. It is generally believed that nitrile rubber products have anti-static performance, while PVC and latex do not have anti-static performance, which is not applicable to ESD areas.
In fact, the anti-static property of Ding Qing gloves also depends on the formula made of glue. The ESD performance of products made of glue from different manufacturers is different, which has little to do with glove manufacturers. Even products made of the same glue have different performance. Therefore, Ding Qing gloves can be used as general anti-static gloves, but their performance is lower than that of professional anti-static gloves.

Attention shall be paid to wearing Ding Qing gloves:
1. Do not wear rings or other jewelry;
2. The fingernails should be trimmed regularly and not too long to avoid damage to the fingertips of gloves;
3. Prevent piercing by sharp objects, such as needles and toothpicks;
4. To take off gloves, you should slowly withdraw from the wrist, not from the fingers;
5. Pay attention to the size when selecting. Too small will cause blood flow disorder, and too large will easily fall off;
6. Regular inspection is required, and it can not be used again if it is damaged.
Precautions for PVC gloves:
1. Disposable PVC gloves do not have high temperature resistance and insulation properties. It shall not be used in high temperature workplaces or as insulating gloves.
2. Once the disposable PVC gloves are cut, the protection effect will be affected
3. The disposable PVC gloves should be kept dry and ventilated during storage to prevent moisture and mildew.
4. When using disposable PVC gloves. Do not touch corrosive substances.
Precautions for latex gloves:
1. Contact with chemicals such as acids, alkalis and organic solvents should be avoided.
2. If you are dealing with infectious substances, you should choose powder free and low protein latex gloves. Powder free and low protein latex gloves can reduce the risk of allergy. But the so-called hypoallergenic latex gloves can not reduce the risk of latex allergy, but can only reduce the allergic reaction caused by chemical additives in latex gloves.
3. Firmly implement the code of practice to reduce the opportunities for latex hazards. For example:
1) Do not use oily hand cream or make-up water when wearing latex gloves, as it may cause deterioration or damage of latex gloves.
2) After removing or removing latex gloves, wash your hands with mild soap and completely dry your hands.
3) The disposable latex gloves shall not be worn repeatedly (because the gloves may have lost the ability to prevent harmful substances).
According to data statistics, 417 billion disposable protective gloves were used worldwide in 2017, accounting for about 64.7% of medical gloves. Among medical gloves, 72% were nitrile and latex gloves. As latex may cause skin allergy and high price for some people, the use proportion of PVC and nitrile in the medical field will gradually increase, latex gloves will decrease in the long term, and nitrile gloves will be the main demand in the future
