What are the differences between anti-static PU shoes and anti-static PVC shoes?
Static shoes, also known as anti-static shoes, anti-static work shoes, are a kind of work shoes for the production of dust-free workshops and laboratories in the fields of electronic semiconductor devices, electronic computers, integrated circuits, etc. to reduce or eliminate static electricity. The static shoes can lead the static electricity of the human body to the earth, thus eliminating the static electricity on the human body, and at the same time effectively suppressing the dust that the workers walk in the clean room.
Anti-static shoes generally use the material of PVC or PU foam to make the sole, which is integrally formed with the upper, and then is reinforced on the upper line to effectively discharge static electricity. The full name of PVC is "polyvinyl chloride", which is a type of plastic. The full name of PU is "polyurethane", which is a type of synthetic leather. PVC and PU materials are commonly used materials for making anti-static shoes. What is the difference between them?
One: From a chemical point of view, PVC and PU are all one of polyvinyl chloride plastics, but the manufacturing process of these two products is different. PU is more complicated in manufacturing process than PVC.
Two: the difference in performance: PVC material's anti-electricity performance is better than PU material's anti-electricity performance; PU sole is resistant to twists and turns, soft and comfortable, good foot feeling, can reduce the fatigue of the staff. The anti-static shoes made of PVC material are thin and hard, and are not suitable for workers who need to stand for a long time.
Three: the difference in price: the price of PU materials is relatively high, and the price of PVC materials is relatively low.
Four: burning smell: After the fire, the taste of PU is much lighter than the taste of PVC.
The above is the introduction of the difference between the PU bottom and the PVC bottom of the anti-static shoes. In the process of purchasing, you can choose the corresponding materials according to your actual needs.
