What functions must the soles of protective shoes have?

          Protective shoes have many kinds of soles according to different functions. Although many friends wear different protective shoes, most people are confused about the materials of soles. They don't know what materials and functions they have. Today, Lai Aime protective shoes will take you to know what soles protective shoes have and what functions they must have.

The soles of protective shoes mainly include rubber soles, polyurethane soles, EVA soles and MD soles.

The rubber sole is wear-resistant, anti-skid, oil resistant, acid and alkali resistant, and water resistant. It has good softness, good shrinkage and elongation. It does not contain water, but it is heavy. It is easy to wear leather for a long time. Rubber is also the main material of tires, so it is also called tire bottom.

The polyurethane PU sole has soft texture, good elasticity, comfortable wearing, and is resistant to abrasion, bending, high and low temperatures, and chemicals. Although there are many advantages, there are also many disadvantages. The main one is good water absorption, which is easy to turn yellow and affect the appearance after wearing, and it is relatively easy to break. Especially, the air permeability is not good, and the anti-skid performance is slightly poor.

The EVA sole is light, elastic and flexible. It is suitable for various climates and environments, but it is also easy to absorb water, and it is not easy to degrade after recycling. It is easy to wear dirty. In many cases, it is extremely dirty after wearing for several hours. The bigger problem is that the EVA sole is easy to be scratched by gravel, iron filings and sharp objects on the ground, and it is not durable.

The MD sole is also light, elastic, soft, easy to clean, and has good hardness, tension and extension. It is also not easy to degrade. It is easy to wrinkle and shrink at high temperatures, and the air permeability is not good after a long time of use. The MD sole is generally EVA+rubber sheet, which has both the soft elasticity of EVA and the oil resistance, water resistance, acid and alkali resistance, anti-skid, wear resistance and other properties of rubber sheet. But the price is relatively more expensive.

Protective shoes are not official names, so the scope is not particularly clear, if it refers to labor protection shoes or safety shoes. Then the sole of protective shoes should have anti-skid function.

Because of the new national standard GB21148-2020 for safety shoes, there are data requirements for anti-skid of safety shoes, that is, a pair of protective shoes that meet the national standard must have anti-skid function no matter what the sole is. This is what each protective shoe sole must do. Do you have any problems with protective shoes? Welcome to contact our Lianchi protective shoes manufacturer.
