At present, the universal isolation protective gloves are mainly divided into natural latex gloves, PVC gloves, nitrile gloves and other synthetic latex gloves, etc. The existence ratio has been stable at 5.5: 3: 1: 0.5 (latex: PVC: nitrile). Next, let¡¯s briefly analyze the advantages and disadvantages of various gloves in terms of function and scope of use:
1. The problem with latex gloves is human allergies caused by natural latex gloves. There have been cases of death due to allergies in foreign countries, which limits the promotion of latex gloves. At the same time, the price of natural latex continues to rise, leading to rising costs. Therefore, the future trend of latex gloves is that the market share is gradually replaced by PVC and nitrile gloves.
2. PVC gloves have good performance. The production process of this kind of gloves is simple, the price is low, and the strength is large. At the same time, PVC gloves have good isolation performance, acid and alkali resistance, and do not contain substances that cause human allergies. They can be widely used Medical, electronics, health protection, home care, beauty salons and many other industries, but the elongation rate of this kind of gloves is not good. At present, latex gloves with added elastomer have been introduced to improve this performance.
3. Nitrile latex and neoprene latex gloves: use nitrile latex and neoprene latex as raw materials. These two kinds of gloves have high strength, high elongation and good hand feeling. They are ideal substitutes for natural latex gloves. It should be noted that the residual toxic acrylonitrile and chloroprene content in the gloves should be strictly controlled, so production control The cost is high, and the environment will be polluted during the production process. The cost of environmental protection treatment is relatively high. These two kinds of gloves also have allergic problems, but they are not serious.
4. Polyurethane latex gloves: Using polyurethane latex as raw material, it is produced by dipping. This kind of glove has high strength, good elasticity and hand feel, and is more comfortable to wear. Its performance is similar to that of natural latex gloves. However, the price of such gloves is high, the cyanide produced during burning is highly toxic, and the use is also restricted.
5. PE gloves: use PE film as raw material, produced by hot melt. This kind of glove is cheap, but it has low strength, low elongation and bad hand feeling. It is generally only used in daily life and ordinary work, and its application in medical operations and medical examinations is very limited. The outstanding advantage of this kind of glove is that there is no allergic problem and it is an absolutely safe glove.
The future development trend of protective gloves in the world requires gloves to be more environmentally friendly in selection of materials and better in performance. Through the analysis of the functions of various gloves, it can be seen that the market pattern of gloves in the future is that the share of latex gloves is gradually decreasing, replaced by PVC and The share of nitrile gloves and other latex gloves has increased, among which PVC gloves have the most promising development prospects.
