TPR shoe material has the characteristics of high elasticity and low temperature resistance of rubber. It has the advantages of low temperature resistance, strong bending, good air permeability, low density, high bonding strength, and waste recyclability. It is a new type of high-performance and easy-to-process material. The tpr material of the sole is actually a thermoplastic rubber material. This material has very good elasticity, the sole is non-slip, and the weight is also in the middle of many materials. The price is also moderate and not very expensive, so it is widely used in a variety of soles.
TPR is a thermoplastic elastomer plastic, which is a functional elastomer plastic modified by compounding with SBS as the base material. The density of TPR material is 0.85~1.2 g/cm3, the hardness range is Shore 0-100A, and the appearance is transparent, translucent or natural round particles or diced particles. TPR material is also called thermoplastic rubber because it has the elasticity and physical properties of rubber. Thermoplastic rubber, that is, it can be melted and plasticized when heated, formed while hot, and the finished product is obtained after cooling, without the need for vulcanization and cross-linking like natural rubber and synthetic rubber to have performance. Some people in the industry also call TPR TPE, which is actually a matter of habit. TPE, which is often mentioned in the elastomer industry, is an elastomer material modified by compounding with SEBS as the base material. Therefore, TPR and TPE are slightly different in material microstructure, which is reflected in the material properties. Since TPR is modified from SBS material containing unsaturated bonds, its chemical resistance, temperature resistance and hydrolysis resistance are not as good as TPE. The surface of TPR raw materials is bright and easy to make into various brightly colored products. TPR is easy to stick to glue and easy to spray and screen print. It can be used as the raw material of beauty and hairdressing equipment, various toys, spray and screen printing toys, and shoes. TPR can also be used as the raw material of sports equipment, handles, handgrips, handicrafts, and sex toys. The base material SBS for producing TPR can be used as the raw material of ink and coating. In short, TPR is a new type of environmentally friendly soft rubber material, non-toxic, halogen-free, phthalate-free, and meets ROHS, REACH (SVCH), EN71, PAHS, NP, FDA environmental testing standards. It is the preferred raw material to replace environmentally unfriendly PVC raw materials. TPR is easy to process and has a short molding cycle. It can replace rubber and be used for rubber parts, etc. TPR materials are widely used in toys and crafts, tool accessories, automotive industry, medical industry, wires and cables, daily necessities, etc.
