Among the combinations of safety shoe sole materials on the market, double-layer soles have become the most convenient and best solution. The wear-resistant and non-slip properties of the outsole can protect the sole of the foot, and the light and soft characteristics of the midsole can be used to protect the sole. To achieve comfort when walking, reminder: This article does not discuss rubber soles.
The current best combination method is RU/PU. Rubber (RU) is used to make the outsole, and polyurethane (PU) is used as the midsole. Then the outsole is made by adhesive or chemical adhesion and the adhesion function of PU itself. Glue it to the midsole.
There is also a combination of sole materials, PU/TPU (polyurethane/thermoplastic polyurethane). The outsole made of thermoplastic polyurethane is extremely tough and wear-resistant. The midsole is made of polyurethane, which is comfortable and convenient to wear. The outsole made of thermoplastic polyurethane meets the needs of contemporary designers. This is because the sole made of TPU can produce colors. Bright soles, and the carving craftsmanship on the soles can also be varied
The soles can be made into a single color or two colors. It mainly depends on the market positioning and design concept of the safety shoe developer. Do not choose safety shoes based on the color. It depends on the needs of the work. It is best to choose the best from the company’s budget. It is best to be in the working environment in advance. After trying it on, choose the appropriate variety. Puqibeian provides anti-smashing and anti-puncture safety shoes, anti-static safety shoes, acid and alkali resistant safety shoes and other categories of try-on trial services.
The other is a double-layer sole made of PU/PU (polyurethane/polyurethane) material combination. Both the outsole and the midsole are made of polyurethane. For the outsole, a particularly dense polyurethane material must be used to maintain the abrasion resistance and method characteristics of the outsole; for the midsole, for comfort considerations, foamed polyurethane must be selected
