When you buy safety shoes, you will see many different soles, so some people will ask: Which kind of safety shoes sole material is better? How to choose the most suitable sole material? Today I will talk to you about this issue and introduce to you the 7 materials commonly used in safety labor protection shoes to help you understand more.
1. Rubber (RB): The advantage of natural rubber is that it is very soft and has excellent elasticity. It can be used for various sports and plays a shock-absorbing role. However, its disadvantages are also obvious, namely, oil resistance and ozone aging resistance. And poor resistance to thermal oxygen aging.
2. Polyurethane sole (PU): Compared with ordinary rubber soles, polyurethane soles have the characteristics of light weight and good wear resistance. Polyurethane soles use polyurethane resin as the main raw material, which solves the problem that domestic plastic soles and recycled rubber soles are easy to break and the rubber soles are easy to peel off.
3. Imitation leather bottom (PVC): With the development of man-made technology, it has replaced natural leather in most areas of life due to its various performance materials and other characteristics of natural leather. It is currently widely used in making bags and clothing. , shoes, vehicles and furniture and other decorations. There are outstanding special needs in terms of touch, elasticity and visual effects.
4.MD sole: MD sole is also called PHYLON sole, commonly known as flying dragon, which can reduce the burden on the feet. The midsole for general shoemaking is a mixed material made of heated and compressed EVA foam (it is an EVA secondary high-pressure molded product). It has the characteristics of light weight, elasticity and good earthquake resistance.
5. TPR sole: The TPR material of the sole is actually a thermoplastic rubber material. This material has very good elasticity, and its weight is relatively middle among many kinds of materials. The price is also relatively moderate, not very expensive, so it is widely used. Used on a variety of shoe soles.
6. EVA sole: EVA sole: The sole has high resilience and tensile strength, high toughness, good shock-proof and buffering properties, excellent heat insulation, thermal insulation and cold-proof and low-temperature properties, can withstand severe cold and exposure, closed cell structure, non-absorbent, It has good moisture-proof and water-resistant properties, is resistant to chemical corrosion such as grease, acid, alkali and other chemicals, and is antibacterial, non-toxic, odorless and pollution-free.
7. Polycarbonate bottom (PC): Polycarbonate (PC) resin is a thermoplastic engineering plastic with excellent performance. It has outstanding impact resistance, good creep resistance and dimensional stability, heat resistance, low water absorption, Non-toxic, with excellent dielectric properties, PC bottom has the characteristics of good weather resistance, beautiful appearance, impact resistance, high light transmittance and strong plasticity.
The above is an introduction to the 7 commonly used sole materials for safety labor protection shoes. It can be seen that the 7 materials have different advantages and disadvantages. It is best to consider factors such as price, performance, use environment, cost, and raw material prices. Today I will explain so much to you. I hope it can help you.
