TPR means thermoplastic elastomer. Beef tendon sole is also a common name for plastic sole. Some places call the tendon bottom TPR, or good leather. Some TPR shoes are made of soles.

TPR material is a mixed modified material with thermoplastic styrene-butadiene rubber (such as SBS and SEBS) as basic raw material, resin (such as PP and PS), filler, plasticizing oil agent and other functional additives.

Beef tendon soles can be made of rubber or plastic, and thermoplastic rubber (TPR) is the most convenient one. At first, it started with rubber beef tendon. At that time, it was mainly to connect this color with other materials after making sandals, which is called beef tendon color.

This kind of sole is most suitable for leisure sports shoes, which are very soft and elastic, very comfortable to wear, strong in fastness and silent when walking.

The bottom of rubber tendon will turn white after a long time, and there is a layer of foggy secretion on the surface; Cut a little with a blade and ignite it with fire to black ash, leaving a little white solid, which is difficult to drop when burning, and there is a little black smoke in the rubber stench.
