Anti-static shoes protect the safety and health of production workers and ensure the quality of the products. So if anti-static shoes sole yellowing phenomenon, will not affect the performance of anti-static shoes it?
In fact, the cause of anti-static shoes yellowing is the material of the sole. This material is PU material. U is a polyurethane material that is easily degraded when exposed to air. It takes a long time to become yellow and hydrolyzed, and gradually becomes light yellow. As the use time goes by, the sole becomes more and more yellow. The anti-static shoes, the color of the soles of the shades of yellow, is due to people wearing different habits.
PU material is the main material for making anti-static shoes. It has the advantages of low density, soft texture, good elasticity, comfort, and light weight. It is suitable for staff who need to stand for a long time. The disadvantage is that the sole is easy to yellow, which does not affect the anti-static performance of anti-static shoes. If the sole is yellow, you can still use it safely.
