What is TPR??
Thermoplastic rubber (TR or TPR), one of the most common materials for making footwear out-soles, has been in use in the footwear industry since the 1960s. TPR is a form of synthetic rubber which is thermoplastic – meaning it melts into liquid form when heated and becomes solid when cooled.
There are a number of reasons for its popularity as a soling material, not the least of which is its ease of molding. As a thermoplastic it is readily injection and molded to form out-sole units, typically at a temperature of around 180 °C. Just a couple of minutes later the TPR will have solidified and the out-sole can be removed from the mold. Other advantages include: slip resistance of TPR solings which is superior to almost every other common soling material; flexing resistance is also very good, performing particularly well at very cold temperatures; it can be made in a wide variety of colors, even translucent; good adhesion strength to upper/mid-sole materials can usually be achieved, if the bonding surface is properly pre-treated using halogenation - a process which adds chlorine to the polymer structure.
