Identification of sole materials for anti-static shoes
When buying anti-static shoes, we are most concerned about anti-static performance and wearing comfort. Then you should have some understanding of the anti-static sole material in order to buy anti-static shoes that meet the requirements. How to distinguish common anti-static shoe soles? Let's take a brief look at it below.
At present, the main materials for the soles of anti-static shoes on the market are three kinds of TPR (thermoplastic elastomer, also known as thermoplastic rubber, which is a material with both rubber and thermoplastic properties), PVC (polyvinyl chloride, made of vinyl chloride in the initiator) Under the action of polymerized thermoplastic resin), PU (polyurethane, an emerging organic polymer material). Of course there are also soles of other materials. So here is a simple way to distinguish these three types of soles by weight.
Among the three, PU bottom anti-static shoes are the lightest and most wear-resistant. Of course the price is also the most expensive. The sole of the PU material is easy to recognize, light in the hand, and the holes on the back of the sole are round.
There are many people who can't tell the difference between PVC and TPR soles. In fact, these two materials are very easy to recognize. The sole of PVC material is heavier than TPR in the hand. The elasticity of the sole of TPR material is better than that of PVC. The easiest way is to hold the sole firmly and fall down naturally. If it can bounce, it is TPR. The sole of PVC material is cheaper than TPR, but the quality is not good, especially in winter, it is easy to break the sole.
When purchasing anti-static shoes, you should always pay attention to the weight of the sole. Over time, with more contact, it is easy to tell what material the sole is.
