Can ESD anti-static shoes pass the test of high temperature sterilization?
Anti-static shoes, labor insurance shoes, their sole materials are generally divided into three types, SPU, PU and PVC. Of these three materials, SPU is generally used for anti-static slippers. It can be molded at one time and is relatively light. The difference between PU and PVC is relatively easy. From the corner, the base fabric of PU is much thicker than PVC, and there are also differences in hand feel. PU feels softer; PVC feels harder; The smell is much lighter than that of PVC. Sometimes, just by looking at the real thing, you can see the difference. But what I want to say today is a dangerous factor that everyone will ignore when using this type of product: high temperature resistance!
Enterprises that purchase anti-static shoes and dust-free shoes have many dust-free workshops in their production workshops, some of which are of high specifications, and even the clothes and shoes of the staff must be sterilized in a professional high-temperature disinfection room. However, they often ignore one of the most important points, what is the high temperature resistance of these three kinds of shoes?
The sole of PVC has no fixed melting point and has a large polydispersity. The molecular weight increases with the decrease of the polymerization temperature. It starts to soften at 80-85°C, becomes viscoelastic at 130°C, and turns into a viscous fluid state at 160-180°C. . The high temperature resistance of SPU soles is between 80-150 degrees. The high temperature resistance of PU soles is the best among the three types, injection melt temperature: 190-210°C injection mold temperature: 20-40°C extrusion melt temperature: 180-210°C, Vicat softening point 120-190°C , the shrinkage rate is 1-2%, so how to achieve high temperature resistance?
Through research, special PU rubber material is used to achieve: heat insulation, flame retardant, waterproof, anti-stab, anti-oil, anti-skid, steel bottom plate, anti-chemicals, and electrical insulation effects. There are many styles of anti-static shoes. For workshops that require high-temperature operation, or customized labor insurance shoes and anti-static shoes at high temperature, please contact us.
