[tips] What are the materials used in labor insurance shoes?

First, the sole material

There are common rubber, vulcanized rubber, or polyvinyl chloride. The function of the sole is mainly abrasion resistance, chemical resistance, heat insulation and oil resistance, but due to the different characteristics of various materials, the function is also different. The shoes of the safety shoes are equipped with steel sheets on the mezzanine to prevent the soles from being nailed or hard objects piercing. In addition, soles made of certain materials can reduce the generation of static electricity or relieve the speed of electrostatic discharge. This controls the potential for static electricity to cause an explosion or fire.

Second, the body of the shoe

Commonly there are leather, artificial leather, polyvinyl chloride and synthetic fibers. These materials have their own advantages. For example, the leather body is more durable and more comfortable to wear, but its anti-corrosive liquid damage function is not good. Artificial leather can be applied in the case of waterproof, corrosive chemicals or other contaminants, but if the surface is depleted, the function will be affected. PVC is most suitable for use in wet conditions and is also easy to clean but can be decomposed by some chemicals. Synthetic fiber shoes are easier to clean and resist chemical decomposition.
